GRIPP 2019 6.Influenza is a heavy infectious process characterized by rapid development, rapid propagation and frequent mutation of the pathogen. In 2019, four strains of viruses - Michigan, "Hong Kong", "Colorado" and "Phuket" were intensified at once. These viruses are striking the human body in a short time and often cause the development of severe complications. Mass outbreaks of influenza from the middle of the autumn are fixed in most regions of Russia, and the final peak of morbidity traditionally occur at the end of February.

The greatest susceptibility The infection is noted in persons with a weakened immune system. Hardly all the flu suffers from a risk group: children, old men, pregnant women, people with chronic pulmonary and heart pathologies, medical workers. It is most often that they are most often developing dangerous complications on the part of the bronchopulmonary structures and hearts flowing in severe form.

Diagnosis of influenza Based on characteristic clinical symptoms. Laboratory studies typically confirm the intended diagnosis. In general blood analysis, signs of viral inflammation appear: leukopenia, lymphocytosis, monocytosis. PCR diagnostics allows you to determine the genetic material of the pathogen in the biomaterial from the patient. Currently, this technique is the main and most accurate as possible.

Physic treatment etiotropic, antiviral. Patients also prescribe pathogenetic, disintellation and symptomatic therapy. With a timely manner, the treatment prediction of pathology is favorable.

GRIPP 2019 7.The classification of the causative agent of infection is its antigenic structure. There are three types of disease: A, B and C. The first two are considered the most dangerous for a person. . Type C is rare, strikes the most weak people, often flows in asymptomatic or light form, does not lead to the development of severe complications. This strain is not included in modern complex anti-infamous vaccines.

  • Type A - Michigan (H1N1). This is the pathogen of swine flu, which is extremely dangerous and actively mutating virus. He is able to resist human immunity, infect the body and cause severe complications. Almost immediately after infection in patients, the temperature of up to 40 ° C sharply rises, weakness, drowsiness, the swelling of the mucous membranes appears. The type of influenza type A is also called pandemic, distinguished frequent deaths.
  • Type A - "Hong Kong" (H3N2). This is the most aggressive strain, capable of very quickly spread among the population. Its epidemics begin violently, develop rapidly and cover large groups of people. This type is characterized by a short incubation. It is able to be transmitted to a person from birds and animals, often hidden under the mask of a banal cold and is complicated by severe pathologies.
  • Type in - "Colorado" and "Phuket". These strains do not cause pandemic, are causes of local flashes of influenza, have similar clinical and epidemiological signs. They are also included in a complex vaccine that protects immediately from all mentioned viruses.

Distribution of influenza infection It occurs airborne droplets with sneezing, cough, close communication with a sick person. In more rare cases, people are infected with contact and domestic paths - through kisses, hugs, household items.

From this article you will learn what a new virus will be this year. Be sure to explore the symptoms of flu 2021 to know when you need to urgently access the doctor.

Influenza in 2021 - This is the epidemic of new virus strains that have already been mutated from past years. Because of this mutation, viruses and bacteria appear, which affect the human body in a short time, with severe complications and a long period of recovery.

Virologist predict at least 3 new strains. In addition, this season with similar symptoms is Coronavirus COVID-19.

  • The main peak of the epidemic falls on the autumn-winter period. In the spring, the second wave of the epidemic is usually covered.
  • But in the fall, you should be careful and carry out preventive measures, although it may not help.
  • How to treat flu in 2021 and what are the main symptoms of the disease this year? Answers to these and other questions are looking below.

What a virus goes now: flu strains 2021

Symptoms of influenza 2021.
Symptoms of influenza 2021.

According to the prediction of virologists, this season, people will suffer from a new type of influenza, which will also include strains of previously known viruses: Brisbane, Michigan and "Hong Kong" and mutating new ones. Scientists predict a real epidemic. It will be difficult to infect this virus, as they mutated, and the virus turned into a dangerous and unpredictable strain. At this time, there are such common strains of influenza disease. These are viruses:

  • Virus A / Guangdong-Maonan / SWL1536 / 2019 (H1N1) PDM09;
  • Mutated from the virus A / Hong Kong / 2671/2019 (H3N2);
  • Mutated from Virus B / Washington / 02/2019 (B / Victoria Lineage);
  • Virus B / Phuket / 3073/2013 (B / Yamagata Lineage).
  • Influenza A - Dangerous Virus . Transmitted from a sick organism healthy. Even your home friend can get sick - a cat, dog and others. This type of influenza has been successfully mutated for many years and becomes resistant to medication.
  • H1N1 (Pork Flu) - 9 years ago, this virus caused a whole epidemic. Complications are manifested in almost every case, and light and bronchi are affected.
  • H5N1 (Bird Flu) - This virus is dangerous by the fact that mortality occurs in 70% of cases. The mutation of the virus continues, so it becomes more and more resistant to medicines.
  • Influenza B. - This virus is not as dangerous as bird or pork strains. It is almost not subject to mutation, easily transferred and treatable.
  • Influenza S. - such a virus is infected by units, therefore the risk of the epidemic is minimal. Proceeds without symptoms and in a light form.

Now, in autumn, the flu epidemic is not yet, but there are isolated cases of the disease. Disease if progresses, then without complications and sharp symptoms. With the onset of cold weather, the picture will change. Therefore, you need to know about the symptoms of the virus, how to deal with it and whether the prevention exists. Read about it below.

Flu symptoms 2021 in adults and children today

The manifestation of the virus this year will directly depend on which strain will progress more. Each type of influenza has an incubation period when diseases are just beginning to show themselves. At this stage, it is important to start treatment and then complication and unpleasant consequences can be avoided. The incubation period usually lasts from 2 to 4 days.

Almost always symptoms of infection with influenza virus in adults and children are similar:

  • Children's organism It is more difficult to transfers the disease due to the end of the developed immunity.
  • Human organism of old age Due to age, it is already weakened and it is harder to fight viruses and bacteria.
  • If an adult middle-aged person can transfer flu "on the legs", the child or old man will lie in bed, without getting up due to the lack of strength to fight with strong virus and bacterial intoxication.

When the flu virus gets inside a person, symptoms will be :

  • High body temperature, fever.
  • Painful sensations in muscles, lubrication in the joints.
  • Weakness, chills.
  • Dizziness, headaches, increase blood pressure.
  • Nausea, vomiting, no appetite.

You should know: If these symptoms do not pass within a week, then the presence of viral or bacterial infection is supposed. Pneumonia, angina and complex concomitant diseases can develop, which are much more difficult to treat than the virus itself.

Remember : When first symptoms appear, immediately contact the doctor to prevent the development of exacerbations!

Forms of influenza in 2021 and their symptoms

High temperature - the main symptom of influenza of different shapes. The main primary symptom Coronavirus COVID-19 In most cases, the loss of smell, sometimes taste. The rest of the symptoms of influenza and coronavirus COVID-19 are similar. However, when coronavirus, with light symptoms, there may be significant lung damage.

There are 4 forms of influenza, which differ from each other by the clinic:

  • Easy - The body temperature does not rise above 38 degrees, there is a decrease in appetite and slightly noticeable headaches.
  • Middle severity - The body temperature is consistently held for 3 days, but does not exceed the mark of 39 degrees. The development of the virus of such a form is accompanied with an edema of the nasal mucosa, pain in the throat and dry cough.
  • Heavy - body temperature up to 40 degrees, fever, nausea, headaches.
  • Hypecoxic - The danger of influenza of this form is that the disease develops very quickly with the advent of a strong runny nose, headaches, cough. It may even be bleeding from the nose, vomiting or simply keeps the sickening condition, hyperemia of the face.

You should know: With some types of influenza, even a digestion disorder may appear, for example, a long diarrhea.

It is necessary to immediately cause a doctor to a house or ambulance if there are such symptoms:

  • Skiddy.
  • The temperature is 40 degrees that holds for three or four days.
  • Strong headache.
  • Red spots, pimples on skin.
  • Cramps.

In 2021, each of the influenza viruses will manifest themselves among each person individually. The immunity of man plays a big role. At risk of developing exacerbations People with chronic ailments in the lungs, heart and vessels.

In the risk group of infection with a particular virus are children, pregnant women, people with chronic diseases, old men, medical workers.

New flu - with temperature, no temperature, mutated intestinal, bird, pig, Hong Kong flu: treatment, latest news

Flu, like many other viruses, is transmitted by air-droplet. On predicting virologists and bacteriologists, In 2021 and early 2022 For a short period of time a large number of people will be affected.

  • A person will feel all the symptoms of the influenza disease, except for one very important - an increase in temperature.
  • The new virus is the infection of the organism that will flow at no temperature.
  • Although the children's organism and the host of the older people can react precisely with increasing temperature.

Latest news: What a virus will be - intestinal, bird, pork or Hong Kong flu, is still unknown. But already experts say that viral infection will flow at no temperature, especially in adults - young and middle-aged people with good immunity. Do not forget that when coronavirus with similar symptoms, the smell disappears most often, a person does not feel smells.

The new virus will evoke such symptoms:

  • Sore throat
  • Aspiced voice
  • Coughing
  • Weakness, driers
  • Nasal congestion
  • Headaches
  • Lomotation in tele

Already when the first symptoms appear, you should immediately begin treatment to avoid exacerbations. Be sure to take antiviral drugs: Kagole, Arbidol, Cycloferon other. Some categories of people well helps to cope with the disease at the first symptoms drug " Rens ".

But when the first signs of complications appear, the doctors prescribe antibacterial drugs:

How to distinguish an ARVI from influenza 2021, Coronavirus COVID-19?

Distinctive features of the virus and conventional cold
Distinctive features of the virus and conventional cold

Influencing disease is easy to confuse with an ordinary cold, as the symptoms are almost similar. The flu appears as a result of the penetration of rinovirus. The cold is a slight inflammation of the mucous membranes of the nose and throat without complications. The virus is more often evolving in winter, as it is active in the cold season. To distinguish the influenza virus from ARVI or Coronavirus COVID-19, attention should be paid to the details:

Symptoms Flu ARVI Coronavirus COVID-19
First symptoms The first symptoms of the virus Notice immediately after infection. The head begins to hurt dramatically, throat. Rubber appears, weakness. Improper treatment can lead to complications and even a fatal outcome. With a cold, the first symptoms There are gradually growing character and a few days after the treatment take place. Loss of smell and possibly taste
What is characteristic of diseases Strong cough, sore throat and chest. Easy cough, campaign and small runny nose. Secondary symptoms in different people may be similar to both influenza symptoms and ORVI
Pain in the head: whiskey, heads, frontal part Migraine Easy pain Migraine
Lethargy Strong discomfort Easy drip Varying degrees
Muscle pain Strongly manifest exactly with influenza Almost not Often severe lubrication in the body
Unpleasant feelings in eyeballs, tear Such symptoms arises due to virus poisoning viruses Almost not Different people may be similar to both influenza symptoms and ORVI
Treatment time Long with complications Disappears within a week without complications From the asymptomatic 2-week quarantine to several months of intense therapy in the hospital.

Usually, on the 2-3rd day, it becomes clear - flu is influenza or ordinary cold or COVID-19. In winter, it is better to begin antiviral drugs on the first day of the disease, "Rens" to prevent the development of complications, because hazardous viruses and bacteria can be progressing in the body.

Remember: Any medicine should only be prescribed by the doctor. Doctors know about the epidemiological situation and on the basis of this, put a preliminary diagnosis, prescribing treatment.

Prevention of influenza and coronavirus COVID-19 in 2021

The main and effective way of prevention is vaccination. But the vaccination must be made no later than October, otherwise the antibodies will not have time to develop in the body and the man in the winter will still get sick, in addition, after the influenza vaccination, it is necessary to be promoted against the coronavirus COVID-19.This it is possible to increase the body's protective forces:

  • Take vitamins with microelements, especially zinc and vitamin A (protects the lungs), C and vitamin D (responding to a large extent for immunity, and in the sun shortage of the Sun has a deficiency of more than 70% of the population).
  • Comply with Hygiene Rules : Wash your hands with soap after a hike to the street, before meal and so on.
  • Lead a healthy lifestyle : Make morning gymnastics or engaged in other exercise, a lot of walking in the fresh air, to eat correctly.
  • Night sleep should be at least 7-8 hours.
  • Improve psycho-emotional background , not nervous on trifles.
  • Minimize contacts with infected people.
  • To refuse from bad habits.
  • Monitor dense, viscosity and oily blood. Contain hemoglobin, cholesterol, protontine . The upper and lower boundaries of the indicators of the norm are undesirable. Golden middle better.

At the first symptoms of influenza, it is better to muffle it immediately in the bud, do not give it to develop in a complete measure with the whole spectrum of complications.

Flu 2021 is a new virus which mutated for many years and in the last with Coronavirus COVID-19. Disease is dangerous and rushes a threat to people with a weak immunity. But still complications and unpleasant consequences can be avoided if the first symptoms appear in a timely manner, to ask for help to doctors and begin treatment. Influenza vaccination 2021 or coronavirus COVID-19 - Best prevention.

Be healthy!

Video: Influenza Symptoms

Flu - Respiratory disease caused by one or more strains of influenza viruses. It is considered one of the most common diseases in the world. Wears seasonal character. Every year, a large number of influenza cases are recorded in Ukraine, as evidenced by statistics.

For example, in the period 10.28.2019 - 11/03/2019 was recorded 147,499 cases Influenza and ORVI. And in 2020 for the interval October 19-25 Influenza And ARVI struck 163,314 people. Both indicator below the epidemiological threshold installed in Ukraine, but this does not mean that we can neglect the rules of prevention and safety.

Each of us is aware of the influenza. But it is always worth using only evidential, correct Information about influenza , Be careful to yourself, as well as know how to help yourself and close in case of illness.

Symptoms and signs of influenza

For some reason, we are very dismissively refer to this viral infection. However, this is a serious illness, which is characterized by severe symptoms, frequent complications, in some cases - lethal outcome.

The first thing we must learn to do is to distinguish the flu from a cold and ORVI. ARZ, to which we are "accustomed" can provoke more than 300 species of various viruses, while the flu is different strains (varieties) of one virus. The course of disease is also different.

Online Moz Ukraine , as well as CDC. There are tables that allow each person to evaluate the symptoms and determine for themselves than, most likely, he fell ill. You always specify the same information at the time of reception for the diagnosis and assessment of the complexity of the process.

Influenza disease

In addition, separately stand out Symptoms signaling about the critical condition of the disease. If you or your loved ones are observed at least one of the signs listed below, you need emergency medical care.

Symptoms of severe flu in children:

  • difficult, rapid breathing;
  • Shinny shade of skin, "blue" lips;
  • Inhalation is accompanied by "pulling" edges;
  • chest pain;
  • The child is difficult to move, strong muscular pain;
  • Signs Dehydration: Dry mucous, crying without tears, lack of urine release more than 8 hours;
  • Excessive lethargy, rejection of interaction during wakefulness;
  • convulsions;
  • body temperature is about 40 ° C;
  • Fever (any) in children under the age of 12 weeks;
  • Episodic cough attacks and temperature rise (swing better / worse);
  • The aggravation of chronic diseases.

Symptoms of severe flu flow in adults:

  • shortness of breath and difficulty breathing;
  • pain and pulling, squeezing feelings in the chest, stomach;
  • lethargy, incapacity, confusion of consciousness, dizziness;
  • convulsions;
  • Long absence of urination;
  • strongly pronounced pain in the muscles;
  • Excessive weakness, "instability";
  • Episodic cough attacks and temperature rise (swing better / worse);
  • The aggravation of chronic diseases.

This is a generalized list of symptoms, in the presence of which you need to immediately consult a doctor or call an ambulance. As with any disease, manifestations can be individual. Therefore, the conclusions about your condition should make exclusively the doctor.

If you suspect or close flu, you should sign up for the therapist or family doctor, children - to the pediatrician. In R + Medical Network, several professionals are received daily, so that you can always get a qualified advice if necessary.

The cause of influenza

Being a respiratory infection, the virus is transmitted by air-droplet - from a sick person to healthy during sneezing, cough or a banal conversation. "Infected" drops fall on the mucous membranes of a healthy person, penetrating there in the epithelium and producing viral protein.

When this protein becomes too much in the same cell, the capture of adjacent cells is carried out. Thus, with an increase in the amount of viral protein, the body includes its protection in the form of immunity, and we feel all the symptoms of the disease.

In fact, the temperature, cough, sneezing, chills are a normal reaction of the immune system to the "invasion".

Influenza spreads With relatively close contact. You must be near the patient at a distance of 1.8 m (6 feet) so that the virus from the sick person fell into your body.

Infection through objects is extremely rare. If for a moment before that, any thing kept the patient with the flu, and immediately handed it to you, be careful. Do not pick up your hands to face, but immediately wash with soap.

How many infectious people sick with flu are infected?

Note that the body's reaction in different people is different. A healthy adult person a few days after infection may not feel any symptoms, but will already be infectious about 1 day before the first signs.

But the total duration of "infectiousness", based on the characteristics of the body, approximately the following:

  • 1 day to the first symptoms and for 3-4 days from the beginning of active illness;
  • 1 day to the first symptoms, during the disease and 5-7 days after it;
  • Small children and people with a weak immunity can stay for a long time.

Grip season Coincides with cold weather. This is usually October-April. Influenza activity and its peak varies annually. It depends mainly on weather conditions, movement of the population inside the country, etc.

Influenza disease indicators

Therefore, you need to be especially careful during this period. Avoid clusters of people, follow the way of life, diet and comply with the rules of hygiene.

If it happened that you still have become infected with the flu, be sure to consult medical attention to avoid unwanted consequences.

What complications gives flu

As practice shows, most patients are recovered for several days, sometimes the disease lasts up to 2 weeks. But in some cases serious develops Complications after influenza :

  • bronchitis;
  • pneumonia;
  • EHA infections and nasal sinuses;
  • myocarditis (myocardial inflammation);
  • Encephalitis (inflammation of the brain);
  • Myositis, Rabbomioliz (inflammation of muscular fabrics).

If you are watching the therapist in R + Medical Network, when the first suspicion of complications after influenza is found, the therapist / pediatrician will send you to a narrow specialist for additional advice and diagnostics.

In the event of the lesion of the ENT organs (otitis, sinusitis, laryngitis, frontit items, etc.) you will need a consultation of a otolaryngologist.

In the presence of shortness of breath, pulling the painful pain, be sure to visit the cardiologist for the cardiogram, the echo of the heart.

With damage to the nervous system, a neurologist will help you. And with permanent pain in the muscles, sensations, when the joint is "cool", sign up for the reception to the rheumatologist.

What specifically the specialist you need, check with your therapist or pediatrician.

When should you consult a doctor?

If you briefly answer this question, then: at the first signs of the disease. As soon as you felt ailment, the body temperature sharply increased, you "breaks", znobit, constantly want to sleep, there is a possibility that it is influenza. So it's time to go to a doctor or sign up for online advice.

If you decide to "watch for themselves" for several days, and the situation is aggravated or does not occur, do not lose time, contact a specialist.

If you are in the risk group, then you should sign up for the therapist or family doctor now.

The risk group includes:

  • people over 65 years old;
  • pregnant women;
  • Children under the age of 5;
  • People with immunodeficiency, onco-scabers;
  • People suffering from chronic diseases (diabetes, cardiopathology, asthma, etc.)

Influenza treatment in R + Medical Network

In the medical centers R + on the street. E. Konovalz, 34a (Pechersk) and ul. V. Kasasi, 2/1 (Teremki) take high professional therapists and pediatricians daily. You can choose to visit any convenient time.

Reception occurs by appointment. To sign up for a consultation, be sure to call our contact center, and you will be offered options available for writing.

During the reception, the doctor carefully examines you, and also surrounds, asking questions about the course of this disease, accompanying, chronic diagnoses, your predispositions and even heredity. We recommend providing detailed answers to all questions. This will help the doctor quickly and correctly determine the tactics of treatment.

In order to confirm the diagnosis of "flu", you may be suggested to pass the express test for influenza. This is a short manipulation in place. For this, an individual test system is used, capable of determining in capillary blood. The presence of influenza a and v. virus.

Further, depending on symptoms, you will be assigned drugs or additional diagnostics.

Note that with a light form, medication therapy is not recommended. You will be prescribed medications aimed at removing symptoms: to reduce the temperature, combat pain in muscles and body, headache and other manifestations.

If the flu flows in medium-wing or severe forms, special antiviral drugs can be used, for example, okeltsamivir, zanamivir, etc. rationality of using medication data, as well as the dosage you will indicate a doctor according to the results of inspection and examination.

For additional diagnostics in our medical centers, everything is provided. You can pass the computer tomography of the lungs, ENT organs, ultrasound, echoCG, ECG, pass laboratory tests, etc.

Our therapist allergist Ganza Tatiana Valerevna claims that the best method of treatment is the prevention of influenza. All therapists and Pediatricians R + are evidential doctors. Therefore, they definitely recommend Make flu vaccinations.

Please note that flu strains in vaccines differ from the season for the season. Therefore, it is always necessary to conduct vaccination before the start of the "Pore of the Influenza" - in the fall.

Our therapists often addate with common issues of flu vaccines. We will be briefly replied to several.

Is it possible to get used from influenza in R +?

Yes, we spend Influenza vaccination All age groups of patients. Previously before the introduction of the vaccine you will definitely examine the therapist / pediatrician, and will determine if there are no contraindications for vaccination.

Is the influenza vaccination is not dangerous?

The answer is unequivocal - not dangerous. Vaccine Contains inactivated (almost dead) virus, which makes the exceptional role of the "simulator" for your immune system.

Temporary minor post-calcinal reactions for 72 hours after vaccination are considered the norm. It can be:

  • pain in the place of injection;
  • feeling of malaise, fatigue;
  • temperature increase;
  • headache.

If you interfere with these sensations - take "reserve preparations" (paracetamol, ibuprofen) in the dosage physician to reduce the temperature or removal of pain syndrome.

Who can be vaccinated from influenza?

There is a very small percentage of people who are contraindicated with flu vaccination. Rather, on the contrary, people with chronic diseases should be vaccinated due to the increased risk of infection with flu and the development of severe complications after it.

And if we generalize: the influenza vaccination is needed to everyone.

Does vaccination guarantee that I can't get 100% influenza?

Unfortunately no. But your body will be a "sign" with a virus and ready to fight him. As you can read in the instructions for any flu vaccine, if after vaccinating you and get sick with the flu, then in a light form and with a low risk of complications.

Complications of influenza

In addition to the desired vaccination, you should perform prophylactic measures every day. Rather, make it in your way of life to stay healthy.

Prevention of influenza

  • Avoid close contact with people, even if they do not have respiratory symptoms. Treat all, especially during the coronavirus epidemic, as a potentially infected;
  • If you feel ailments, stay at home, insulace from others. Use personal protective equipment if you are in the same room with other people without full insulation;
  • use individual dishes, towels;
  • Follow the rules of personal hygiene. Make your hands more often. Do not leave the items that use in publicly available places;

Until 2013, three peaks of viral morbidity were noted annually - late autumn, in winter and early spring, but at one time the disease caused only one strain of the influenza virus, then the other was replaced by another. In recent years, strains A and B are circulated at the same time, several other "colds" viruses causing ARVI. After overgrowing with one infection, you can get another strain and ORVI within a month, and so in a circle.

How long is the flu are sick?

From 5 days to two weeks, everything is determined by the causative agent of infection.

  • It is believed that the first three days clinical manifestations are only developing.
  • The next three days proceeds the "period of acute phase", when all the symptoms have reached maximum development.
  • In the second week, it may be completed or complications begins, and this is the most critical time for the patient.

If the disease occurs, it is necessary to immediately turn to the infectious doctor who leads without weekends and holidays in the clinic "Medicine 24/7". Previously, the beginning of therapy will avoid irreparable consequences.

For their own life, a person has been safely tolerated with flu, if there is no exaggerated response to the introduction of the virus - the "cytokine storm", which is able to bring to death.

How does the flu begins?

From infection until the first symptoms may pass only a few hours, but in most cases - from 2 days to week, this time is called the incubation period.

The disease always begins acutely, almost without preparation. That's just an hour ago, a person felt perfectly and unexpectedly "fell". Suddenly, intoxication is developing with cinema and strongest headache when it hurts even to open his eyes. Weakness increases, dizziness interfts move, break all the muscles and joints. During the few minutes, the temperature exceeds the mark of 38 C.

The infection in the strain can begin gradually, but the symptoms are pronounced quite significantly.

When does flu symptoms appear on the side of the respiratory organs?

In contrast to ARVI with flu, the runny nose appear not earlier than the second day of the disease, and the intensity of the Qatar of the upper respiratory tract is strongly inferior to the symptoms of intoxication. There is no abundant discontinated from the nose, the nasal is expressed, the dry cough prevails, the perfigure and foreigners behind the sternum.

For influenza, a combination of three signs is characteristic:

  • Sudden start;
  • Pronounced intoxication;
  • Fever with cough due to tracheit development.

The clinical symptoms of influenza is more commonly manifested by chills and light-in-friendly with a tearing, a runny nose and a throat.

With the uncomplicated flow of flu symptoms in an adult there is no more than 5 days.

In the clinic "Medicine 24/7", there is a 24-hour examination on high-precision equipment, which allows you to quickly put the correct diagnosis and immediately begin treatment of the influenza virus.

What does the patient look like with the influenza?

Very unimportant, he is not able to stand nor sit. Frightened face, fined. Lips are blue or just pale. Eyes red and visible extended minor vascular. Nasal bleeding is possible, bruises are easily formed, and when the tonometer cuff is removed after measuring the pressure, the vascular stars are formed - petechia.

When the patient's condition should cause serious anxiety?

Signs of the progressive flow of influenza in adults, when dangerous symptoms are developing and inpatient treatment is required:

  • The development of pulmonary heart failure with a deterioration in blood oxygenation when blood pressure decreases, shortness of breath appears at rest or with a slight movement, the chest hurts and the sputum with strengths of blood is distinguished.
  • The defeat of the central nervously system, which is reflected in the mental state and changes consciousness up to the confusion, everything is aggravated and, possibly convulsion.
  • Signs of dehydration in the form of a pressure reduction, a small amount of urine, increasing lethargy when dry skin and mucous membranes.
  • For more than three days, high temperatures can talk about the attachment of a bacterial infection.

In the event of the above described symptoms of deterioration of the course of the disease, it is necessary to immediately turn to the infectious doctor who leads without weekends and holidays in the clinic "Medicine 24/7", the recording is carried out around the clock by phone +7 (495) 230-00-01. Previously, the beginning of therapy will avoid irreparable consequences.

Are complications often arise?

The possibility of the development of symptoms of complications of influenza depends on the aggressiveness of the viral strain and the initial state of human health. On average, each seventh-tenth patient, as a rule, elderly patients and pregnant women are burffined by chronic diseases.

Viral pneumonia begins in the first three days of the disease, by the end of the week viral-bacterial pneumonia develop, and tertiary bacterial pneumonia arises in the second week of flu.

For in influenza, there is a complication from the ENT organs.

When is the recovery?

Not earlier than all the symptoms of intoxication disappear, there is not a single sign of inflammation of the upper respiratory tract, the normal temperature lasts for three days. Weakness can still stay, but every day it will be less and element better.

The whole range of diagnostic events in the "Medicine 24/7" clinic is performed on a guaranteed high professional level, the most effective domestic and foreign techniques of therapy are used, which makes it possible to significantly improve the quality of life of our patients and maintain their activity.

Self-confidence with unhealthy costs very expensive, get help of an infectious examiner in the clinic of infectious diseases by calling: +7 (495) 230-00-01.

The flu epidemic is usually moving from east to west. The incidence of the population is accompanied by three splash - peaks, the first occurs at the end of the autumn and early winter, then in the New Year holidays and the third - on the border of winter and spring.

What influenza pathogens cause epidemics?

The cause of influenza is three viruses: A, B and C. Only strain A is able to exist in the human body, animals and birds, and all of them from time to time are sick. Strains in and C are purely human inhabitants and no more animals from the world.

Today, infectious agents can circulate at the same time, and in one family or institution alone patients with influenza A, others in, and the third - ORVI. After recovery from one infection, the diseases caused by other strains can be transferred.

In the event of a viral disease, it is necessary to immediately turn to the infectious background, which leads the reception without weekends and holidays in the clinic "Medicine 24/7", the recording is carried out around the clock.

How is the name of the virus decryp?

In 2016, the virus A (H1N1) circulated, which caused the high incidence of middle-aged people. It is clear that and denotes the strain, and what is H1N1?

To facilitate the introduction into cells on the surface membrane of the causative agent of strain A, protein processes are located. Some processes consist of hemagglutinin (HA), in total, 18 options for this protein, which helps to be embedded inside the erythrocyte. Other processes are represented by 11 types of neuraminidase enzyme (Na), which helps the viral particle to be selected from the cell outward.

According to what protein proceeds are made, and began to signify the subtypes of the virus. Thus, the name A (H1N1) denotes that on the virus a strain there are spies from 1 hemagglutinin subtype and 1 subtype of neuraminidase.

Do not hope that many times have suffered a viral infection and at the next epidemic, complications will be passed. The body does not become newer, so the flu is not at all the fact that infection in maturity.

How does the influenza virus damage the cells?

The virus is highlighted with microscopic moisture droplets with breathing, with then saliva. The cause of the disease is a viral particle entering the upper respiratory paths of a healthy person. With the help of HA processes, the infectious agent is pierced inside the cell where the process of its division launches. New norinal particles already with Na's processes are selected from the cell outward.

The cell affected by the virus produces protective inflammatory factors, which should destroy the inner enemy, but in this deadly broth, called the "cytokine storm", and the cell itself also dies. The released toxic products violate the biochemical processes in the cells of the heart, lungs, brain, leading to the exacerbation of chronic diseases. After such an attack, immunity decreases, and then the offensive of bacteria and mushrooms begin.

What can be the cause of the death of the influenza virus?

The virus is not very alive, depending on the microclimate, it retains the viability of not more than 8 hours, frost and heat can cause his early death.

It does not endure with high temperatures, it takes a little higher than 75 ° C for his death, so it is enough to quiet the dishes of the patient with boiling water and "please" his lingerie.

The reason for the unconditional viral death is to process the hands and surfaces with alcohol or hydrogen peroxide, conventional soap and ultraviolet radiation. But the iodine solutions of antiseptics work not very actively, it takes long contact and concentration.

Protection against influenza virus

The cause of the disease is to obtain a virus with ducks of saliva infected. With a sick family member or in transport, not only an air-drip transmission is likely, but also a contact method with the transfer of an infectious particle with a blurred hand on the face. The best way to protect yourself from heavy flu and its complications is to make influenza vaccination.

To reduce personal susceptibility to infection follows:

  • To lead a healthy lifestyle, that is, not to overeat, sleep normally, to be physically active.
  • If you have chronic diseases, you need to be observed by a doctor, because exacerbations reduce the body's immune defense.
  • In the epidemic period, drug prevention is possible, especially when contacting patients. Drug emergency and seasonal antiviral prevention, which increases the resistance of the human body to respiratory viruses.

If you have a chronic cause to reduce the resistance of the body, they had contact with the patient or simply want to increase the body's stability to an infectious agent, "Medicine 24/7" experts will select an individual preventive program. Refer to the infectious background in our clinic of infectious diseases for help, call: +7 (495) 230-00-01.

Most people consider each cold with influenza, "I am influenza" - they say with a strong cold with tearing and malaise. Then the flu is not hurt every year, and several times a year carry a variety of respiratory viral infections.

In the clinic "Medicine 24/7", not only in the shortest possible time and with minimal costs will establish the correct diagnosis, but also the influenza virus is optimal treatment for world clinical standards, taking into account the individuality of your body.

Laboratory diagnosis for influenza

The diagnosis of viral disease in adults is simple, quite a medical examination, without analyzing the identification of a specific pathogen. The epidemic season circulate certain strains - types of flu virus viruses, and by and large to any patient is enough to carry out adequate treatment and put it on his feet, and it doesn't matter what strain struck his health.

In favor of influenza infection, says:

  • Specific clinical picture;
  • increased morbidity of the population by viral respiratory infections and influenza;
  • disease in the epidemic season for infection;
  • The causative agent of the disease is expected in advance by the World Health Organization.

When does a doctor assign diagnostics?

The diagnosis of the pathogen is carried out in hospitalization in the event of a severe course of infection and the development of complications. The virus is looking for complex laboratory methods:

  • In any secret - the release of the patient, it does not matter, in the blood or saliva, by the method of polymerase chain reaction (PCR), a particle of the genetic apparatus of the virus - RNA is detected.
  • Blood is taken to carry out the hemagglutination braking reaction (RTHA), at which antibodies to the virus are found.
  • An immuno-immunimal analysis (IFA) and the method of immunofluorescent microscopy reveal signs of the presence of the virus - antigens in a washout from the mucous membrane.

If you have signs of respiratory viral infection, do not attempt to make a diagnosis yourself. A lot of serious diseases in early development takes place under the influenza mask.

Effective influenza prevention

Annually by the beginning of the fall, WHO announces which strains of the pathogen will cause a disease in winter and pharmaceutical manufacturers begin to prepare certain vaccines. Vaccination is not required to everyone, but those who are related to patients, or working in children's teams, can contribute to the spread of infection in a weakened elderly environment. Studies have proven that vaccination is the best prevention of severe illness and its complications, actually reduces the mortality of the population.

Vaccination is carried out either a whole virus or its particles, and causes the formation of immune defenders in the body. Live vaccines are the most effective, but complications cause more. Preparations with a weakened - inactivated virus cause a limited protective reaction, but is better tolerated. Vaccinal immunity arises by the end of the second week and keeps several months.

Only a doctor from all variety of vaccines may pick up the best preparation for you, taking into account possible complications, and predict the optimal immune response. It will not take much time, but will protect you from infection complications. Consult a doctor of the center of infectious diseases. Sign up for infectious source: +7 (495) 230-00-01

How to carry out the prevention of influenza and colds if one of the family members fell ill?

If the family appeared in a sick influenza or ORVI, it is necessary:

  • Separate it in the room or at least behind the screen, so that the meter is not healthy family members;
  • To air and wash the floors daily and wipe the furniture;
  • After washing, it's a patient with boiling water;
  • Hands to wash almost the elbow after each touch to the patient;
  • Mask throw out after 2-hour socks.

Family members can begin prevention with medicines with which the flu is treated.

Your doctor can recommend preparations for prevention. They are selected individually. Some of these drugs have serious side effects, so in no case should you deal with self-medication.

Proper diagnosis allows you to assign optimal treatment and keep the disease under control, in the clinic of infections "Medicine 24/7" a full range of complex research is performed. Sign up for an infectious source at a convenient time for you by calling +7 (495) 230-00-01.

Treatment of adult patients with flu consists of compliance with the regime and nutrition, medication therapy.

Every year on the eve of the WHO epidemic, it is notified which viruses will circulate, which vaccines are effective and what should be taken. For result, regardless of the type of strain, take:

  • Anti-happose drugs that stop reproduction of the viral agent and reduce its circulation in the blood;
  • Additionally, anti-inflammatory agents are needed, non-allowing cells to react too actively to the virus - the suppression of the "cytokine storm";
  • And it is necessary to remove intoxication to limit the formation of free radicals that change the structure of the virus and increasing its aggressiveness;
  • To prevent the Bacteriamia began to begin receiving antibacterial agents on time.

In the clinic Medicine 24/7, there is a round-the-clock survey on high-precision equipment, which allows you to quickly put the correct diagnosis and immediately begin treatment. Contact the center of infectious diseases for help, call: +7 (495) 230-00-01

Specialists in the field of health all over the world are trying to find an explanation for a new riddle, which has brought a growing pandemic of a new coronavirus infection. On her background, there were almost no cases of seasonal influenza in the world, which was confirmed, including the World Health Organization (WHO) statistics, writes the British Daily Mail. According to the estimated estimates, the incidence of flu in the world decreased by 98% compared with the same period last year.

Yaromir Romanov / Znak.com

As the publication notes, many feared that the upcoming winter world will cover the perfect storm - "double epidemic", which will supply a system of medical assistance to the edge of collapse. This is when the second deadly wave of COVID-19 coincides with the seasonal flu epidemic, from which about 10 thousand people die in one of the UK annually. The government worked out by these forecasts launched the largest flu vaccination program in the history of the country: vaccination should receive 30 million people, which is 20% more than last year. According to the latest reports, vaccination has already received the highest coverage among the British older than 65 years and children of younger. There is only one curious problem: it looks like the flu almost disappeared.

Information about this began to appear in March, when the epidemic of seasonal flu was found in the northern hemisphere, but the epidemic of a new coronavirus infection came. In the southern hemisphere at that time, autumn was coming, which usually brings an epidemide for the influenza.

But WHO data indicate that in 2020 this lift did not happen.

For example, in Australia in April, only 14 positive influenza cases were recorded, whereas a year earlier there were 367 (a decrease - 96%). In June, when in Australia, seasonal influenza reaches a peak, there were no new cases at all. In fact, from this time Australia did not report on the cases of influenza disease.

The same picture was observed in Chile, where from April to October, only 12 cases of influenza were revealed. During the same period of 2019 there were almost 7 thousand. In South Africa, the control tests revealed only two cases at the beginning of the season, and the statistics fell to zero next next month. In general, it is 99% less than in the previous year.

Interestingly, from the Britain itself since Coronavirus began distributing in March, it was received in WHO only about 767 cases - compared with almost 7 thousand, which were registered from March to October 2019. With the beginning of the new flu season, this fall has become only 0.7% more than a year ago, when the growth was 10% from September to October.

What challenges brought a new COVID wave and what follows. Interview with academician wounds

Experts exclude the possibility that cases of seasonal flu began to include in the statistics of COVID-19 due to the similarity of two pathogens. The influenza virus and coronavirus are very different, and in the laboratories they know clearly. At the same time, the assumption that the presence of SARS-COV-2, causing COVID-19, somehow "crowded" the influenza virus has received scientific support.

Research says that if a person is infected with one virus, he is less likely to receive simultaneous infection to others. In science language, this is called "viral intervention" and is explained among the number of the mobilization of the human immune system, which, struggling against one virus, will attack the other. At the same time there is a factor in competition between the pathogens themselves: hitting a healthy cell, one virus itself effectively displaces another. Thus, if a sufficient number of people are one virus, other pathogens simply will not be able to spread, researchers believe. "Viral intervention" could well be the reason that, contrary to forecasts in 2009, the world did not encounter a pandemic of "swine influenza". The Government of Great Britain then planned the worst scenario - about 65,000 deaths. But in the end, 392 people were killed.

The Chinese study of the two previous flares of coronavirus, SARS and MERS, showed the same effect. Infection by another virus, such as influenza, to some extent protects against coronavirus infection.

The public health service of England after the study of the samples taken about 20 thousand people during the first four months of 2020, concluded that those who had a conventional seasonal flu, the likelihood of coronavirus infection by 58% lower.

Influenza vaccinations: Five myths that are ashamed (and then hurt) to believe

True, there is an assumption that is more related to behavioral constraints. Picking the flu, the patient remains in bed and thus reduces the chances of contact with another virus. Scientists in the overwhelming majority agree that the anomalous decline in seasonal flu is likely to actually be associated with social distances, washing, insulation, closing schools and shops. In the end, all previous studies, as protective masks and social distance mechanism work, are based on preventing influenza transmission. It is not surprising that it worked on the flu.

Specialists see two problems on this encouraging background. One is associated with confidence in influenza statistics: most of the officials recognize that global influenza incidence data this year will not be reliable this year, since the priority in the laboratories received observation of coronavirus. The second reason is not encouraging too much - the flu season in the most populated northern hemisphere began and what happens next - is still unknown. Some indicate that influenza mortality may be low for a prose: many potential victims from particularly vulnerable groups of population groups have already become victims of coronavirus. Therefore, the installation is preserved for the maximum of the large number of people to have time to instill from seasonal flu, makes Daily Mail.

Elderly people and children react more often and sharper. This year, according to experts, there are 3 species of dangerous infection at once.

"According to health services, coming from the countries of the Southern Hemisphere of the Planet, where the seasonal epidemic of flu has already passed, this year in the northern latitudes, in particular, in Russia, the seasonal epidemic of influenza type A H1N1 and A H3N2 is expected. In general, these are the same subtypes of a seasonal virus that are found from year to year for decades, "says Public Health Specialist and Health Specialist Pavel Stotcko . True, the specialist notes, it is worth understanding that viruses constantly mutate, and their proteins, hemagglutinin and neuraminidase, for which doctors distinguish strains and types of influenza virus, changed this year. "And this means that A H1N1 (Michigan), this is not exactly the virus that was in 2016 (California), and certainly not like that was in 1918 (Spaniard). But all the same the flu remains as dangerous as it was a century ago, "says Stalko. WHO specialists add that the flu virus can also appear in Russia.

Hazards a h1n1

Influenza with H1N1 abbreviation in the people is known as pork. It is a highly infectious disease that is caused by a pandemic type of virus transmitted from a pig to a person. Naturally, from person to man, he is also transmitted, which expands the coverage of the fallen.

Complications of swine flu are dangerous to health.The swine flu virus was opened in 1930 in the United States. From the last epidemics that developed on his background, the world remembers the influenza "California" 2009. According to official data published by WHO, 17.4 thousand people died from influenza and the complications caused by them.

Infection with such a virus occurs in two ways :

  • Air-drip: For example, someone sneezed next to another person, the diameter of the spread of dangerous discharge with 1.5-2 meters;
  • Contact-household: the virus is pretty harvest (it can live outside the body up to 2 hours), therefore, it can be preserved a certain time on different surfaces (buttons of elevators, tables, dishes, office workers, etc.)

Risk group for swine flu are :

  • Children under 5 years old;
  • Older people over 65;
  • Pregnant;
  • People with chronic diseases.

The symptoms of flu h1n1 are quite classic. A person can clearly note the time when he suddenly became sharply, the temperature is rising to high numbers, lubrications are noted in the muscles, light-in-friendly develops. The inxication process may be accompanied by nausea and vomiting. Catarial manifestations can be joined: cough, throat pain, nasal congestion.

It is important to remember that one of the most terrible phenomena at this type of influenza is its complication in the form of pneumonia. Inflammation of the lungs is developing instantly and is not always noticeable for a person: just a couple of days it can almost completely destroy the lungs. That is why this type of influenza virus has a large number of deaths. And that is why the patient must observe a daily doctor who will listen to the lungs every day.

Scary a H3N2.

The second version of the influenza, which is waiting for doctors this winter, - ARVI with abbreviation a H3N2. Or, as it is also called, Hong Kong flu. For the first time he began to speak in the sixties. True, then he was not so heavy. But over time, the virus mutated and became more aggressive, so now this infection is extremely dangerous.

Hong Kong flu is transmitted, as well as California, through air and with hands. Therefore, in the season of epidemics it is worth exercising special caution: do not attend the places of massacre of people and more often wash your hands.

Hong Kong flu is a special danger for :

  • Old people;
  • Young children;
  • Pregnant women;
  • People on a diet, especially if we are talking about a diet for weight loss;
  • People with diabetes;
  • People with lung diseases.

Signs of illness again are characteristic of all other types of influenza. On the one hand, it is for them that you can distinguish the flu right away. On the other, it is not always the flu proceeds along a typical scheme. And then there is a risk of missing time. Among the additional features, Hong Kong can be distinguished the appearance of a feeling of cutting and burning in the eyes, pain in the limbs and a dry cough.

The main hazards of such a variant of influenza are the development of myocarditis, all the same pneumonia in heavy forms, encephalitis and state of shock. Some of the persecuted liver and renal dysfunction were manifested, there were failures in the work of the endocrine gland.

Influenza b brisbane - what hides

WHO experts predict and the appearance of the third type of flu: influenza B - Brisbane. It is a dangerous variety of Hong Kong strain. Of the last epidemics of such a disease there was an outbreak in 2007.

It begins, like all other flu variants, with sharp and lightning symptoms. Fever, chills, headaches, pain in muscles, runny nose, fatigue, etc. - all this indicates the appearance of dangerous pathology in the body. Over time, severe depletion and dehydration begin to manifest, dry cough appears. Custom disorders can also develop.

Dehydration is called one of the terrible complications of such an infection. After all, on this background, the body begins to deny enough quickly. Pneumonia can also develop, which additionally pursues human health.

The flu is very contagious. Therefore, it is worth very careful to behave during the risk of the epidemic.

Personal protection

During the flu epidemic, a number of uncomplicated rules must be observed that will allow to protect against infection. First of all, it is necessary to avoid the accumulation sites of people, if there is a need to be in a dense human stream, it is recommended to apply masks. Be sure to comply with the rules of personal hygiene, wash your hands as often as possible: after the street, after transport, before eating, after visiting the toilet. If there is a patient in the house, it is necessary to isolate it if possible: allocate separate dishes and do not use common towels with him.

You can also regularly rinse the nasal strokes with salt solution to wash the virus with the mucous membrane. In addition, the use of vitamins is recommended. It is desirable to establish a balanced nutrition so that the body has forces to fight viruses. An apartment and office premises should be soaked and carry out wet cleaning.

A separate point is such a personal protection as vaccination. "Specialists know exactly the protein composition of the virus surface shell, which means that they are able to" teach "and immunity to recognize the virus with the help of a vaccine. It includes components of the 3-4 most common strains of the influenza virus, "says Stotko.

The vaccination campaign has already started throughout the country. And now the optimal time to put vaccinations, since the body will have time to develop antibodies to the virus. Chief State Sanitary Doctor of Russia, Head of Rospotrebnadzor of the Russian Federation Anna Popova

The World Health Organization (WHO) presented recommendations on the composition of flu vaccines at the epidemic season of 2017-2018 for the Northern Hemisphere, and the composition of the Trohulant vaccine is recommended to include strains similar to what they were included in the vaccine this year for AH3N2 influenza viruses (Hong Kong ) And for influenza B. At the same time, the pandemic strain A H1N1 2009 (California) is proposed to be replaced by strain A H1N1 (Michigan).

Due to the federal budget, 58.4 million doses of the domestic flu vaccine were purchased with relevant strains recommended by WHO, including 17.8 million doses for children. It is 8 million more than purchased last year. The optimal time of the vaccination against influenza is the period from September to November. It is important that the immunity after the influenza vaccination has managed to be formed before the end of the epidemic raising of morbidity.

Vaccination is recommended to all groups of the population, but especially shown to children since 6 months, people suffering from chronic diseases, pregnant women, as well as persons from professional risk groups: medical professionals, teachers, students, service and transport workers.

According to statistics, the flu causes a high mortality, especially if we are talking about type A H3N2 and H1N1 viruses. Elderly people and children react more often and sharper. This year, according to experts, there are 3 species of dangerous infection at once.
