The influenza virus replicates in the epithelium of the respiratory tract, particularly in trochee, destroying it. Over time, particles of influenza virus, as well as the metabolic products get into the blood stream, which leads to a sharp increase in body temperature. At the low tone of the body, the flu virus is able to infect other systems and organs, it can lead to hemorrhagic syndrome.

The similarity of the primary symptoms of the flu with the symptoms of other respiratory infections complicates the correct and timely diagnosis. In the laboratory it is feasible to identify the influenza virus from swabs from the throat or mucosal epithelium of the nasal passage as well as a blood test.
When non-specific laboratory investigations for diagnosis of influenza virus give direction to the General analysis of blood and urine and a chest x-ray to identify complications from the flu. Without the use of laboratory studies of the influenza virus is generally diagnosed based on epidemiological data, when there is concurrent disease of other members of the settlement.
Treatment of influenza is possible even at home. What the method of treatment of the virus is chosen depends on the extent of the disease, its onlinenote, and the age and condition of the patient. In mild course of flu recommended treatment at home with strict bed rest condition.
In this case, the treatment is based on excessive drinking, consumption of antipyretic medications at temperatures of more than 38C, the means of mitigating severe accompanying symptoms (runny nose, sore throat, cough) and other drugs against influenza. Patients with a very high fever and a severe form of flu, be hospitalized, where treatment with antibiotics under the supervision of a doctor.
