Causes of influenza
Influenza is caused by a virus of several types (the most famous types of the virus - A, B and C). Viruses of type A are strong activators of influenza epidemics. So from 1889 to 1892 there were 500 million people suffering from the "Russian head cold", "Spanish flu", of which 22 million have died. We may recall the "Asian flu" of 1950, about half the world's population suffered from this infection.
People of all ages are subject to flu, but the elderly are sick it harder than young.
Treatment of influenza
People get a flu vaccinations in all countries. Immunisation protects against infection in about 80% of cases. However, influenza viruses are constantly changing, and the active substances are used previously for vaccination, lose effectiveness. So every time when there is a new influenza virus, it is necessary to create a new serum drug. As a rule, annual forecasts are created, and a vaccine against a possible epidemic is already ready for the fall. Vaccination protects against influenza is about 1-2 years. For additional protection, vaccination against the disease should be done every fall. But if a person is ill, then the flu virus will not have the proper effect. You can only help ailments, which is caused by the disease.
