Information about the test

Influenza is an acute infectious disease of the respiratory tract caused by the influenza virus of type A, B or C. Type B of the virus is more resistant and is not characterized by such high variability as type A.

Influenza is transmitted from a sick person through the air with droplets of saliva, mucus or sputum. Infection can also occur through household items (personal hygiene items, dishes, toys). Influenza is prone to rapid (epidemic) spread in a fairly short period of time due to its following properties:

  • The infection has a short incubation period (10-48 hours) and is mostly mild;
  • Air-droplet transmission;
  • High susceptibility;
  • Risk of re-infection - immunity is specific only to a certain serotype, and not to all influenza viruses.

Also, a feature of this viral infection is that patients in the incubation (asymptomatic) period or with minor symptoms of the respiratory system practically do not pose an epidemiological danger.

When the flu virus enters the body (or after the vaccination), B-lymphocytes begin to produce special protective proteins - antibodies, which are called immunoglobulins. First, IgM antibodies appear, and then IgG. The latter can circulate in the blood for many years after the infection.

However, the flu can develop again. Nevertheless, IgG immunoglobulins during repeated contact even with a different subtype of the influenza B virus can cause the disease in a milder form without the complications development.
