Epidemiology of Influenza

Epidemiology of influenza involves studying how the flu spreads, who it affects most, and the patterns over time. Influenza is a contagious respiratory virus transmitted mainly through droplets when infected people cough or sneeze. It tends to peak in colder months and can cause seasonal outbreaks worldwide. Factors like vaccination rates, virus mutations, and population immunity influence its spread. Understanding these patterns helps public health officials implement control measures, prepare vaccines, and reduce the impact of flu seasons by targeting at-risk groups and promoting hygiene practices.
