Influenza-like Illness Surveillance

Influenza-like Illness (ILI) Surveillance is a system used to monitor and track the occurrence of illnesses that exhibit symptoms similar to influenza, such as fever, cough, and body aches. Health organizations collect data from hospitals, clinics, and laboratories to identify trends and outbreaks. This helps public health officials understand how widespread flu and similar illnesses are and aids in planning vaccine distribution and public health responses. By studying patterns over time, ILI surveillance plays a crucial role in protecting community health and preventing the spread of infectious diseases.
