Influenza is an acute viral infection that affects the respiratory system, highly transmissible, globally distributed and with a tendency to spread easily in seasonal epidemics, and may also cause pandemics.

According to the World Health Organization (WHO), cases of influenza vary from mild to severe and can lead to death. It is an acute respiratory infection, caused by types A, B, C and D, with viruses A and B responsible for seasonal epidemics. In addition, the influenza A virus is specifically associated with pandemic events, such as the one that occurred in 2009.

Generally, the incubation period for the influenza virus is two days. The infection can be asymptomatic or trigger severe symptoms. Severe conditions occur more frequently in individuals who have risk factors or conditions for the complications of the infection, infants in the first year of life, children from six months to less than six years of age, pregnant women, the elderly aged 60 years or over and people with non-communicable chronic diseases and other special medical conditions.

Transmission occurs through respiratory droplets produced by coughing, sneezing or talking from an infected person to a susceptible person. The flu syndrome is characterized by the sudden onset of fever, headache, muscle aches (myalgia), cough, sore throat and fatigue.
