Flu Outbreak

A “flu outbreak” refers to a sudden increase in the number of cases of influenza, a contagious respiratory illness caused by influenza viruses. Outbreaks often occur in specific geographic areas and can affect a large number of people in a short period. They are typically characterized by a higher-than-expected incidence of illness, which can lead to increased hospitalizations and, in severe cases, mortality. Flu outbreaks are most common during the fall and winter months when the virus thrives and spreads more easily among populations. Public health officials monitor flu activity to mitigate the spread and impact of outbreaks through vaccination campaigns, public awareness, and outbreak response strategies.
