Flu surveillance

Flu surveillance involves monitoring and collecting data on influenza cases to track how the flu spreads and affects populations. Health agencies gather information from hospitals, clinics, and labs to identify outbreaks, monitor virus strains, and understand seasonal patterns. This helps in making informed decisions about vaccine development, public health responses, and preventive measures. By continuously watching flu activity, authorities can detect early signs of severe outbreaks and allocate resources effectively to protect public health.
