What are flu symptoms?
When the flu symptoms start to appear from the General intoxication of the organism. Almost immediately, sharply raises the temperature and starts an inflammatory process in the respiratory tract. Every year, from early November to late April is a viral disease sets in, causing a lot of worries and concerns to physicians and patients.
Almost everyone in their lifetime at least once sick with the flu. Illness does not choose anyone in particular: can get sick and young and old people, a man and a woman.
The flu is not particularly dangerous disease. But the complications to which it might lead, take a lot of trouble to the patient. The most common among them are: bronchitis, tracheitis, pneumonia, inflammation of the maxillary sinuses and the middle ear. Heavier acute cardiac failure, swelling of the brain and lungs.
What is this disease?
Influenza refers to acute respiratory diseases of viral origin. Infection occurs through the respiratory, that is, through the breath (the causative agent enters through the respiratory system). This is the most common disease among diseases of infectious etiology. In a short period of time the flu virus affects a great many people. It is stored at low temperatures and relatively high humidity, so has a season from November to April. In very severe frosts, the outbreak doesn't spread. For him, it's bad.
Influenza virus several varieties. Every year, health statistics record the incidence of virus A, which is the most virulent and contagious. After about 3-4 years recorded increased number of cases of virus B. In institutions frequently registered type C.
Influenza C does not change its form, so they can recover only once for the whole life. Influenza B is changing, but quite rare, and A constantly and dramatically changing. Sometimes you can hear the opinion that of influenza A have more severe. But this is a false statement. For the patient there is no difference what type of virus has infected it. Such grading is only important for doctors, who track the spread of the disease. The virus is A more common due to the fact that is constantly changing.
If a person is sick with a certain virus, then again he will not be exposed to him. But new viruses can overcome a person each year. And even if the patient has already undergone, after your modification may again threaten person.
disease">the Body would be easier to deal with it, as in a modified virus still has components of the previous type.
If in a certain locality no less than 5% of the population registered with the manifestations of influenza, it is declared an epidemic in this city. The same applies to district, region and even the country.
If the incidence is mass (more than half the population infected) in the territory declares a pandemic, that is, following the epidemic phase spread of the disease.
According to who, every year more than 250 thousand people die from the flu. Among them are a large number of children and the elderly, because these groups of people have weakened immune system.
Why is a person infected with the flu?
As causes of infection doctors consider the following:
- diseases of the respiratory system;
- negative bacteria that live in the nose, mouth, trachea and bronchi: to a certain period they do no harm, as they are pathogenic, but given the current favorable environment start its malicious action.
All these features reduce the protective functions of the body. If a person in this condition deals with cases of influenza, then he is infected. A weakened body cannot fight off the pathogen.
The virus enters the bloodstream via the upper respiratory tract. The patient's body is suffering from toxins that excrete virus. Toxic substances affect the nervous system and cardiovascular. Their functioning is disturbed. Then starts crashing in metabolism. This, in turn, also causes low immunity. And low body resistance opens the way for penetration of the virus.
The immune system can be weakened by poor nutrition, unhealthy lifestyle or chronic diseases. Therefore, Contracting the flu may not always. If a person has a healthy body, it is less exposed to any virus, including the flu. As with any virus or respiratory disease, the flu prevention is important.
What are the symptoms in adults?
The disease manifests itself in different ways depending on the shape and course of the disease. The incubation period for the flu lasts up to 2 days. The flu clinic is divided into typical and atypical; the flow - light, moderate and heavy; for complexity - complicated and uncomplicated.

What are the features of the disease in childhood?
Kids get the flu. This does not apply to newborns. This group of children protected by immunity received from mother (if she has the relevant antibodies in the blood). Growing up, the baby loses this protection and is at risk of becoming infected.
Have kids and teenagers the opportunity to pick up an infection is high as they often are in groups where there may be patients (kindergartens, schools). And while at home, the child is at risk: the virus can go from parents, from siblings, from any memberfamily.
The main signs of influenza in children: sudden onset of fever, chills, weakness, dizziness, pain in the joints, muscles, head. Children become lethargic and overwhelmed. This occurs from the toxins produced by a virus. They have a negative effect on the nervous system, causing this condition.
The highest temperature observed in the first days of the disease - about 39 degrees. Fever and chills lasted 4-5 days. The temperature begins to decline. But a possible re-surge of improvement. The main symptoms of flu in children:
- headache in the temporal region;

Annually in medical institutions is carried out mass vaccination, capable to protect from the incidence of the alleged type of the flu virus. Modern medicine uses 2 types of vaccines: products, manufactured based on killed viruses, and the drugs obtained from attenuated live viruses. The second is more efficient because it creates the best protection to the immune system.
Recommended preventive measures. They are the same as with any respiratory or viral illness: healthy life, feasible physical activity, proper nutrition, and the like.
