Flu 2017: Symptoms and Treatment

Autumn-winter period is the time of seasonal diseases, the most common of which is the flu. What awaits us this year, how to prevent the epidemic and cure it?

Influenza is one of the varieties of ARVI, but it is characterized by serious complications that can lead to death. According to the World Health Organization, 3-5 million people suffer from seasonal influenza every year. people, and 250-500 thousand cases end in a lethal outcome.

The disease is transmitted by airborne droplets with a distance between healthy and donor not more than 3 meters. You can get infected and through the objects on which there are aerosol particles of the patient's coughing. Getting into a healthy body, the virus weakens the defenses of the immune system, opening the way for other diseases.

World Flu 2017 - already on the threshold

The beginning of the epidemic is projected for the last months of autumn and the beginning of winter, that is, for the first colds.

The global flu of 2017, according to many experts, will begin with China. This is due to the increased population density, a large population of pigs and birds. Proceeding from this, it can be concluded that again we will have to face H2N2, which unlike in 1957 will be strongly mutated and modified.

Infection with such strains is also possible:

• California - affects both people and animals, transmitted from sight to sight. This virus spread widely in 2009, provoking outbreaks of swine flu around the world. Characterized by permanent mutations. On the symptomatology it is similar to cold, but quickly progresses, accepting the pathological form.
• Brisbane is an Australian virus that spreads quickly. Its peculiarity is that in 25% of cases it causes serious complications.
• Switzerland is a mutated form of the California virus H1N1 type A, which passed into the form of H3N2. On the symptomatology it is identical to the Californian version to which respiratory signs are gradually connected. With timely and correct treatment does not cause complications.
• Yamagata is a relatively safe strain when compared to pork or avian influenza. Rapidly spreading, requires urgent treatment. If the patient is carrying the disease on his legs, then this can lead to serious complications, the most frequent of which are cardiac and pulmonary pathologies.
• Phuket is an unstable virus that is constantly evolving. Frequent mutations lead to a change in the usual symptoms of the disease. It is difficult to diagnose.

Scientists do not exclude the emergence of new types of deadly viruses. To prevent influenza 2017, vaccination is carried out from previously known strains.

The flu epidemic 2017

Every year we are cautious about the flu season. And this is not surprising, since viruses constantly mutate, complicating the process of diagnosis and treatment. According to the scientists' forecasts, this year seasonal illness can turn into a real epidemic of the flu of 2017, which is associated with exacerbation of pneumococcal infections and changes in many strains.

The human body can not develop permanent immunity to influenza, since the virus is extremely variable. To date, there are three serotype types of the disease: A, B and C, which differ in antigenic spectrum and the location of fragments of ribonucleic acid. Each serotype contains a certain subtype - a strain that can change its genetic data under the influence of external factors, that is, mutate.

• And - these are the most severe forms of influenza. This type is divided into several subtypes by the combination of proteins and features of hemagglutinin. Causes disease in humans, animals and birds, with the possibility of transmission of the virus between all species. 2-3 times a year provokes epidemics, active and antigen-unstable serotype.
• B - causes epidemics of a local nature, affecting several neighboring countries. It may be preceded by an outbreak of serotype A. Most often affects children, has a moderate symptomatology.
• C - proceeds in mild form and causes single cases of the disease. Mostly affects children and people with a weakened immune system. It only circulates in the human population, it is antigen-stable.

Having had a single flu serotype, you can immediately get sick with another. This is due to the fact that cross immunity between different strains is very weak.

Flu in 2017 in Russia

The Ministry of Health of the Russian Federation began preparations for the flu in 2017. In Russia it is expected for the beginning of winter - November-January. But already work is underway to create a three-component seasonal vaccine, which will include a strain of the virus B, H1N1 and H3N2. Vaccines are developed for adults and children, which will allow to carry out the prevention in full. Immunization of the population will begin with megacities, since they contain the main transport hubs and a large flow of people.

According to the doctors, the epidemic will not cover the whole country at the same time, that is, the flu will gradually move through the territory of Russia. The virus can come from both China and southern neighbors, that is, from European countries. If we consider the strain structure, then H3N2 (a subtype of the influenza A virus) will be dominant. The main symptoms of the disease are: a sharp increase in temperature, head and joint pain, weakness, runny nose. The treatment will not differ from the therapy of last year's strains. With regard to complications, they are possible with the progression of the pathological condition due to late diagnosis or improper treatment. In particularly severe cases, death is not excluded.

Flu 2017 in Ukraine

According to medical statistics, every 35-40 years, the epidemiological situation with seasonal diseases is significantly exacerbated. Flu 2017 in Ukraine is expected at the beginning of winter, that is, January-February, and flares are also possible in February. This is due to the circulation of air currents that carry the disease from one area to another. According to experts, the virus will come to us from Russia, and to them from the neighbor-China.

Scientists are preparing to meet with mutated H3N2, which can lead to serious complications and death. But do not panic and trust the forecasts, just listen to them.

In order to protect yourself from seasonal diseases it is recommended to get vaccinated. Also, do not forget about preventive measures aimed at strengthening the immune system. When the first symptoms of the disease (weakness, fever, runny nose, headaches and muscle pains), you need to seek medical help. Timely and correct treatment, will avoid influenza complications.

Flu 2016-2017: special risk groups

Like any disease, the 2017 flu has high-risk groups that are divided according to the medical and epidemic factors.

Medical:

• Patients over 65 years of age and newborns.
• People with chronic diseases: bronchopulmonary and cardiovascular system, kidney damage, endocrine pathologies, kidney, liver and blood diseases.
• Pregnant women and women planning a pregnancy.
• People who are in special groups (homes for the disabled and the elderly, boarding schools)

Epidemiological:

• People in contact with a large number of potentially infected (workers in the service sector, trade, public transport and others).
• Medical workers, teachers.
• Babies attending kindergarten or school, students.

The chance of contracting significantly increases with a weakened immune system. To prevent seasonal influenza vaccination is recommended, and compliance with preventive measures.

Influenza 2017 season - the infection is already in the air

With the advent of the first cold weather, the issue of infectious and catarrhal diseases takes on special urgency. And this is not surprising, since from year to year a mutating virus affects more and more people, causing many painful symptoms and serious complications. The danger of the disease in this period is due to the weakened body. Seasonal virus is in the air and summer time, but the chances of catching it are minimal. This is due to the fact that the body receives solar energy and vitamins, which increase resistance and increase the immune status.

In itself, the flu is not dangerous, in contrast to its atypical form, which is characterized by rapid development and the risk of death. Also, do not forget about the new strains, the spread of which in large areas causes epidemics, paralyzing the lives of many people and even entire countries. The disease spreads by airborne droplets, and in different climatic zones at different times, but always with the appearance of colds. Let's consider in more detail the pathogenesis of influenza:

• Penetration into the respiratory tract and reproduction in epithelial cells.
• Passage of factors of nonspecific airway resistance.
• Gradual destruction of affected cells.
• Catarrhal syndrome, toxemia.
• Restoration and formation of immunity.

In order to get infected, just a few minutes in the same room with the patient. The disease has a short incubation period, so the first symptoms can appear a couple of hours after infection. According to medical statistics, every eighth adult and every fourth child are sick during the epidemic.

According to its symptoms, the season of influenza 2017 will not differ from previous ones. Infection is characterized by such signs: a sharp fit of chills, drowsiness and fatigue, joint and muscle pain. If there is a fever and a cold, then this is a clear manifestation of seasonal flu. At this stage, the immune system comes into contact with the virus. Discomfort can last for a couple of days, after that, well-being improves. If this does not happen and the disease progresses, then it threatens with serious complications.

Symptoms of the flu 2017

The flu is characterized by an acute onset and a short incubation period of 1-2 days. The clinical picture is accompanied by catarrhal and intoxication syndrome. The disease causes severe headaches, a sharp rise in temperature, a runny nose, coughing, chest pains, it is also possible nosebleeds and sensitivity of the gums. Because of unstable blood pressure, tachycardia and bradycardia may develop. There are painful sensations in the muscles, joints and bones. Cough can be complicated by tracheitis, and hoarseness of voice and violation of breathing point to croup.

Symptoms of influenza 2017 depend on its stage and form:

Light (subclinical)

• Weakness and headaches.
• Raise body temperature to 38 ° C.
• Pronounced hyperemia of the larynx, throat and nose.
• Weak or absent infectious toxicosis.

Medium-heavy

• Severe intoxication (chills, increased sweating, headaches and muscle pains, weakness).
• Body temperature up to 39 ° С.
• Catarrhal symptoms (congestion of soft palate and posterior pharyngeal wall).
• Respiratory pathologies (runny nose, chest pain, cough, larynx and trachea).
• Diarrhea and attacks of vomiting.
• Possible complications (otitis, sinusitis, neuritis).

Heavy

• Body temperature up to 40 ° С.
• Confusion of consciousness.
• Muscle cramps.
• Hallucinations.
• Disorders from the cardiovascular system (nosebleeds, hemorrhages in the soft palate).
• Complications of varying severity (bacterial infections, bronchitis, pneumonia, tracheitis).

Hypertensive

• Severe respiratory failure.
• Hemodynamic disorders and encephalopathy.
• Body temperature is above 40 ° C.
• Hyperthermia (dehydration, rapid breathing, hypoxia).
• Meningism (irritation of the brain or spinal cord).

The latter form in most cases becomes the cause of death. The presence of dangerous cerebral syndromes is due to the neurotropicity of the influenza virus. Encephalic, meningic and convulsive symptoms occur against a background of high temperature. These symptoms can be accompanied by abdominal syndrome, dyspepsia, pain in the digestive tract, attacks of nausea and vomiting.

Features of the flu 2017

Every year, experts of the World Health Organization give a forecast for which strains of influenza will be active in the upcoming epidemic season. According to experts, features of the flu of 2017 will consist in the circulation of three strains: H1N1, H3N2 Hong Kong and Brisbane. Swine flu is known to the world since 2009, so most of the people developed immunity to it. The remaining two strains are new, so an increase in the incidence rate is possible.

The first waves of seasonal illness are already on the way, but its peak is expected for January-February. The rise in morbidity is associated with the arrival of colds and the spread of respiratory viruses. As in previous years, vaccination is the best way to prevent the disease. To vaccinate better in September-November, this will enable the immune system to develop the necessary antibodies and to resist the virus. Timely prevention and proper treatment will prevent various complications of the disease.

Complications of the flu 2017

Incorrect or untimely treatment of acute infectious diseases can cause serious complications. Flu 2017 is capable of provoking such pathological conditions:

1. Complications of the respiratory system are the most common pathologies. Patients face bronchitis, lung abscesses, pneumonia, sinusitis, sinusitis, otitis.
   • Pneumonia can be caused by viruses and bacteria. It is characterized by a sharp increase in temperature, which persists for a long period of time, a dry cough with blood, increased sweating. This condition requires urgent treatment, since without medical assistance leads to death.
   • Sinusitis - inflammation of the maxillary sinuses. Without proper treatment, the infection spreads throughout the body. The patient complains of nasal congestion and thick discharge from the nasal sinuses, headaches and toothaches, discomfort when pressing on the cheek and forehead.
   • Otitis is an inflammatory lesion of the middle ear, which can lead to hearing loss. Patients suffer from shooting pain in the ear, purulent discharge and fever.
2. Complications of the cardiovascular system - shortness of breath, rapid heartbeat, pain in the heart. Very often, the flu provokes inflammation of the heart muscle, which in turn causes heart failure.
3. Diseases of the nervous system - polyneuritis, neuralgia, inflammation of the meninges and other pathologies.
   • Meningitis - headaches, nausea and vomiting, photophobia.
   • Arachnoiditis - raspiruchenie headaches, discomfort in the forehead and nose, attacks of nausea and dizziness.

In order to avoid complications of influenza, it is necessary to follow preventive measures and not engage in self-medication.

What is the difference between a cold and flu?

Light malaise, weakness, fever and chills are the first signs of the disease. What is the difference between a cold and flu if the symptoms of these pathologies and the pathways of infection are similar?

1. Influenza is an acute infectious disease, its virus spreads quickly and mutates, which leads to frequent epidemics.
2. Colds are a disorder that occurs due to hypothermia of the body. The main symptoms are manifested from the respiratory system, gradually developing into more complex forms.

Influenza is an independent disease with acute symptoms, and cold symptoms depend on its localization. That is, it can proceed both acute and lethargic, but it does not cause life-threatening complications. It is very important to distinguish between pathology data. The main risk group for both diseases are people with weakened immune system, children, pensioners, pregnant women. Flu and cold have a similar symptom, but their manifestations have a number of distinctive features:

• Infection - with the virus, the virus spreads abruptly, the symptoms develop very quickly. With a cold, the infection affects the body slowly and sluggishly, the symptoms are progressive.
• The first signs - with the flu, the temperature rises sharply, accompanied by an ache in the body, headaches and intoxication. With a cold, there is a runny nose, a sore throat and a cough, a subfebrile temperature.
• Cough - a cold is characterized by a slight sore throat, which can go into a gross cough. With the flu, cough is accompanied by abundant sputum and chest pains.
• Headaches and muscle pain - the flu causes severe intoxication and discomfort throughout the body. There may be attacks of nausea and vomiting, severe convulsions, and pain in the eyes. For the common cold is characterized by a state of weakness and weakness.
• Recovery - the duration of this period is completely dependent on the immune system. The cold passes faster and does not cause complications. The flu is characterized by a prolonged recovery, which is accompanied by weakness and drowsiness.

Knowing the main differences between flu and cold, you can independently determine the onset of an acute seasonal disease. This will allow to take appropriate medical measures and reduce the risk of complications from the disease.

How to treat the flu in 2017?

The main danger of an acute infectious disease is a rapid development. Knowing the symptoms of the virus and how to treat the flu 2017 can prevent its complications. At the first signs of malaise, it is recommended to consult a doctor. Self-medication for influenza lesions is unacceptable, especially for children and people of advanced age.

For treatment of seasonal influenza infection 2017, it is necessary:

• Abundant drink, healthy food and rest - the patient needs rest, hot drinks in the form of herbal teas, morses, natural juices and a full balanced diet.
• Antipyretics - to facilitate the condition, it is recommended to take Paracetamol, Acetylsalicylic acid, NSAIDs.
• Vasoconstrictors for the relief of nasal breathing and medicines for liquefaction and sputum discharge.
• Antitussive medications are prescribed to relieve pain in the chest caused by a strong, crampy cough. Most often, patients are appointed with Percussin, Libexin, Tusuprex, various herbal preparations for wet and night cough.

All medications should be prescribed by a doctor. It is better to treat flu after consultation with a therapist.

How to prevent the flu in this season 2016-2017?

Autumn is in full swing, so the prevention of viral diseases is quite urgent. In order to prevent the flu in this season 2016-2017 it is necessary to adhere to such recommendations:

1. Strengthening the protective properties of the immune system

• Full nutrition and sleep.
• Physical activity.
• Admission of vitamin and minerals.
• Hardening.
• Rejection of bad habits.

1. Vaccination is recommended for people with chronic diseases, for children, the elderly, pregnant women. Vaccination is necessary for everyone, whose work is connected with a large number of people (sellers, social workers, teachers, doctors, military and many others).

Allocate such types of vaccines:

• Live all-virion - they include a living virus, which when ingested creates an immune system to a specific strain. May cause adverse reactions and has many contraindications.
• Whole-virion - contain the killed, purified virus. They have fewer drawbacks than living ones, but they are still very rarely used.
• Split vaccines - they include internal and surface antigens, which due to special purification have a minimum of adverse reactions and contraindications.
• Subunit - contain surface purified virus proteins. Much safer than split-vaccines are used to prevent seasonal diseases.

All of the above vaccines have different indications for use and a number of contraindications. That is why anti-influenza immunization should be carried out only in the medical field.

1. Personal hygiene - since the flu is transmitted by airborne droplets, compliance with basic hygiene rules will prevent infection. To reduce the risk of infection, you must:

• Do not contact closely with the patient and use a mask if necessary.
• Frequently wash hands with soap under running water or use alcohol-containing products, napkins.
• Regularly ventilate the living area and carry out a wet cleaning.
• Do not touch the face with dirty hands.

Prevention can also be done with the help of special medications. Typically, this is necessary for people who have come into contact with an infected or have a weakened immune system. To prevent the disease use standard anti-influenza drugs, but in a smaller dosage.

The flu of 2017, like the seasonal epidemics of previous years, can provoke high mortality. The risk of death is associated with the development of dangerous complications of the disease and its improper treatment.

General characteristics of the H3N2 flu and treatment of the disease

H3N2 influenza is a relatively young strain.It is dangerous because of insufficient knowledge. In addition, this variety of the strain of the virus can provoke a person to develop complications with hemorrhagic lesions.

General information about varieties of the influenza virus

The influenza virus belongs to the family Ortomyxoviridae, which also includes Influenza A, B, C. The affiliation of the virus to one of them is determined by the antigenic properties of the virion proteins. More detailed division of different types of viruses is carried out in accordance with the subtypes existing on the surface of the virus of proteins - hemagglutin (NA) and neuraminidase (NA). At the moment, 16 subtypes of HA and 9 subtypes of NA are known.

Specific epidemics for humans are viruses of three types of HA. These subtypes include H1, H2 and H3. Viruses A and B contain NA and HA, which play the role of the main structural components of the virus. The influenza C virus does not have neuraminidase. The viral particle of influenza C contains haemagglutinin-esterase (penetrating) protein.

The strand of RNA, which is a part of the virus, is surrounded by a protein and packed into a membrane consisting of lipoproteins. Virions have the ability to agglutinate erythrocytes and enter into them with the help of virus-specific enzymes.

Influenza A H3N2 is a subtype of influenza A virus.

The name of the species of the virus is based on the names of the recombination of genes.

The influenza virus has a spherical shape, having a diameter of 80-120 nm. At the center of the viral particle are eight fragments of RNA. Each of the available RNA fragments is encapsulated in a separate capsule of lipoproteins, the surface of which has spines. Antibodies produced by the body in response to hemagglutinin (H) and neuraminidase (N), are the basis of the body's immunity against a particular type of virus.

Viral particles have an unusual property, which is uncharacteristic for viral particles, fragmentation of the genetic material and high protein variability. The proteins that make up the virus particles can dramatically change their properties. This phenomenon is called antigenic shift. It leads to the appearance of varieties of virus particles causing a pandemic.

The new form of the virus particle undergoes a slow change in properties, called antigenic drift. This phenomenon contributes to the extension of the emerging epidemic.

Susceptible to influenza virus are all age groups of the population. The source of infection in society becomes a sick person with a pronounced form of the disease.

Symptoms of the H3N2 Influenza Virus

Most often, the clinical picture of the disease manifests itself 12-48 hours after the moment of infection. This strain of the virus is characterized by a very rapid process of reproduction of viral particles in the body in the epithelial cells of the respiratory tract. The disease develops very quickly, literally for several days.

The most vivid symptoms manifested with the development of influenza H3N2 in the body are the following:

• • development of chills;
  • the occurrence of severe headaches;
  • the appearance in the body of a patient of a strong general weakness;
  • the appearance of lacrimation;
  • development of muscle pain;
  • the appearance of aches in the joints;
  • increased sweat production;
  • absence or sharp decrease in appetite;
  • appearance of dryness in the nasal cavity and pharynx;
  • the appearance of a feeling of perspiration in the throat;
  • the appearance of a dry cough;
  • pain in the chest;
  • development of photophobia.

  Sometimes during the development of the disease there is a runny nose. In addition to the characteristic symptoms of influenza in the body when you join the influenza infection of colds, the symptoms of a cold develop.

Carrying out treatment for influenza

The first vaccination against influenza was carried out in the early forties of the last century. Almost until the last period, the treatment of influenza infection was carried out by relieving the emerging symptoms. Treatment is carried out by taking antipyretic, expectorant and antitussive drugs. In addition, to strengthen the immune system is used to take vitamins.

When performing treatment procedures, patients are recommended complete rest, and during the treatment requires the use of a large amount of fluid. During the period of illness, you should stop smoking and drinking alcohol. With the development of a cold that is not complicated by a cold, it is not treated with antibiotics.

Used in the treatment of antiviral drugs affect a certain phase of the development of viral infection of the body. For effective exposure, treatment is required before the onset of the first clinical symptoms of infection in the human body. Late reception of antiviral medications is practically inactive and not effective.

To treat the influenza state, two types of medicines have been developed, which are inhibitors of neuraminidase and inhibitors of M2. A separate group of drugs - means based on interferon, which have antiviral, anti-inflammatory effect. In addition, these medications show immunomodulatory activity.

Preparations with inhibitory properties

Preparations that have proven effective in treating influenza infection are oseltamivir and zanamivir. These neuraminidase inhibiting drugs are effective against most influenza strains, including avian and porcine strains. They contribute to the suppression of the spread of the virus in the human body, while reducing the severity of the emerging symptoms with a simultaneous reduction in the duration of the disease and the incidence of secondary complications.

The use of these drugs, depending on the individual characteristics of the body, can provoke the occurrence of side effects in the body, such as the occurrence of vomiting, diarrhea. Sometimes it is possible to develop mental disorders, hallucinations and psychoses.

The inhibitors of M2 are preparations of amantadine and remantadine, which block proton pumps, which leads to preventing the virus from entering the cell.

Prevention of the occurrence of infection with influenza

The most traditional and one of the most common methods of counteraction is the implementation of vaccination.

The influenza vaccines used can provide moderate protection against the virologically confirmed influenza strain. The effectiveness of the use of vaccination proves its effectiveness for young children.

As a rule, the vaccines used contain antigens of three strains of the virus. Vaccination is considered desirable in at-risk groups, which include children, people in old age and patients with chronic heart and lung ailments. In addition, vaccination is recommended for doctors.

To prevent the spread of infection to strangers in the room where the patient is, regular wet cleaning is carried out using disinfectants.

To disinfect the air, ultraviolet irradiation and special air purifiers are used.

In the case of human infection with influenza in uncomplicated its course, the prognosis is favorable. With the development of complications in the body, there are cases of death for a person.

Influenza A - what is it? Influenza A and B: symptoms and treatment

The flu got its name from the French word "grasp", which characterizes its effect well.

This disease develops rapidly. Since morning, a healthy person starts complaining about health at noon, and by midnight in some cases may no longer have a chance of recovery.

Historical facts

Influenza epidemics periodically cover the entire space of the globe and become a historical fact. For example, from such a type of flu as the Spanish, for 1918 and 1919 people died more than during the entire time of the First World War.

The causative agent, which is considered the cause of the flu, was discovered in 1933 and was subsequently called the virus A.

The year 1944 was marked by the discovery of the virus B, the next - the virus C - was discovered in 1949. Over time, it was determined that the viruses that cause influenza A, B, are heterogeneous, are constantly changing, and as a result of these transformations, a new modification of the flu can appear.

What is the flu

I wonder what the flu A or B. This is an acute infectious disease that begins almost instantaneously. Immediately viruses affect the mucous membrane of the respiratory tract. Because of this, a runny nose appears, the paranasal sinuses become inflamed, the larynx is affected, breathing is disrupted and a cough develops.

With blood, the virus moves through the body and, by poisoning it, disrupts vital functions:

• high fever, often accompanied by nausea and vomiting;
• there are headaches and muscle pains;
• and in some cases hallucinations may occur.

The most severe situations are characterized by intoxication, which leads to the destruction of small vessels and multiple hemorrhages. The consequences of influenza may be pneumonia and heart muscle diseases.

Influenza A and B are types of acute respiratory diseases. When a disease occurs, there is a violation of the human defense mechanism. Under the influence of microbes that are in the upper respiratory tract, cells on the trachea and bronchi die, opens the way for infection in deeper tissues and the bronchial cleansing process becomes more difficult. In this case, the function of the immune system is suppressed. Because of this, a short period is sufficient to initiate pneumonia or to awaken other respiratory viruses.

How is it transmitted

A person is susceptible to a disease such as influenza A and B. This means that the likelihood of getting sick in the second and third time, especially a new subspecies. The disease is transmitted as follows:

• during communication with a sick person, through his droplets of saliva, mucus, phlegm;
• together with food that has not been thermally treated;
• with a direct touch of the hands of the patient;
• through the air, through the dust.

The patient is enveloped by a zone consisting of infected particles, the size of which is from two to three meters. Through any items that were in his hands (for example, the phone, armrest arm, door handle) can catch the flu A.

What is a contagious disease, everyone should know - a person poses a danger to others even during the incubation period, even before he felt unwell. However, on the sixth day from the onset of the disease, he practically does not pose a threat to the health of others.

Influenza A virus

So, the type A flu - what is it? This is one of the most terrible varieties of this disease. Immunity, which is acquired by a person who has had type A influenza, lasts two years. Then it becomes dangerous again.

It is interesting that between human and animal viruses, hereditary materials can be exchanged, and viral hybrids may appear on contact. As a result, the flu can affect not only humans, but also animals.

Approximately, every 35 years, a virus that causes influenza type A also undergoes significant changes. What is it, it is better not to know. After all, mankind does not have this serotype of immunity, as a result of which the disease covers most of the world's population. It flows in a very severe form. And in this case they speak not of an epidemic, but of a pandemic.

Symptoms and peculiarities of percolation

It should be mentioned, telling about the type A flu, that this is a disease that is characterized by rapid spread. The incubation stage lasts from two to five days, and a period begins that is characterized by acute clinical manifestations.

For flu, taking place in mild form, it lasts from three to five days. And after 5-10 days a person recovers. But for another 20 days a person can feel tired, weak, have a headache, be irritable and suffer from insomnia.

Let's list what causes the flu A symptoms in children:

• the temperature rises to 40 ° C;
• the child is shivering;
• the kid stops playing, whines, becomes very weak;
• complains of headache and muscle pain;
• he has a sore throat;
• possible abdominal pain and vomiting;
• begins a dry cough.

Treatment

Treatment includes recommendations not only on the intake of medications, but also on compliance with the regime. Since influenza A and B symptoms and treatment are the same, our advice is suitable for each of them.

During a period of elevated temperature, a person loses a lot of fluid that must be replenished. The first thing you need to do in the period of illness is to drink tea, drinks, decoctions of herbs abundantly. Chicken broth has a good effect on the course of the disease. By increasing the speed of mucus discharge, it reduces the swelling of the nose.

The use of coffee and alcohol causes dehydration of the body, which has already lost a lot of liquid, so it is better not to drink during illness.

What is dangerous about influenza A

What is it - the flu, know almost everything. But the opinion that this is a common disease, which everyone has been ill many times and without consequences, is mistaken. Its main danger is in the consequences that it can cause: pneumonia, rhinitis, sinusitis, bronchitis. It can exacerbate chronic diseases, provoke complications of the cardiovascular system, create problems from the muscular system.

By the way, the type A flu, unlike the disease caused by the B virus, is more dangerous. As a result of this disease, intoxication, hemorrhages into important organs, pulmonary complications, cardiac and pulmonary insufficiency can lead to death.

Prevention

In order not to be among the infected, each of us needs to follow preventive measures that can prevent the flu. And what is it? First of all, you must follow the basic principles of a healthy lifestyle, such as proper nutrition and even physical exercise. It is also important to tempering.

Vaccination helps the body to form immunity to the most expected strain of the virus. The drug is administered 1-3 months before the expected onset of the epidemic.

A cotton-gauze dressing reduces the chance of getting infected through the respiratory tract. The bandage is changed several times a day to avoid getting infected from the bandage itself.

Here are some more tips for prevention:

1. The intake of vitamin preparations increases the protective functions of the body.
2. Garlic reduces the number of microorganisms in the mouth.
3. Avoiding visits to crowded places during an epidemic lowers the likelihood of infection.
4. During the epidemic it is desirable to conduct a wet cleaning of the room daily.
5. Helps protect against microbes treatment of the nasal cavity with oxolin ointment.
6. The use of antiviral drugs protects against the disease.

If the house is sick

Despite some differences, doctors still combine influenza A and B (symptoms and treatment). First of all it is recommended to give the body an opportunity to relax. Due to this, you will help the immune system. The necessary requirement - compliance with bed rest. And most importantly - calling a doctor at home, because it may not be the flu, and what it is - without a specialist's examination is impossible to say.

In order to reduce the possibility of infection of family members, the patient is placed in a separate room or fenced off from the main room. The patient is given separate utensils and hygiene items.

It is necessary and wet cleaning with disinfectants, because thanks to it more than twice the concentration of viruses. A good health effect gives ventilation at least 3 times a day.
