Seasonal influenza viruses in tropical regions may occur throughout the year, causing outbreaks and epidemics more regularly in humans. There are four types or large groupings of seasonal influenza viruses; Influenza A, B, C, and D, but only influenza A and B viruses cause clinically important human disease and seasonal epidemics. It can cause mild to severe illnesses and even deaths, particularly in high-risk individuals. Vaccination is the most effective means of preventing influenza and its complications. Among healthy adults, influenza vaccine provides protection, even when circulating viruses may not exactly match the vaccine viruses. In elderly, it reduces severity of disease and incidence of complications and deaths. Vaccination is especially important for people at higher risk of serious influenza complications, and for people who live with, care for, high risk individuals.
