seasonal flu surveillance

Seasonal flu surveillance involves collecting and analyzing data on influenza cases to monitor its spread and impact during flu season. Health agencies gather reports from doctors, hospitals, laboratories, and the public to track infection rates, identify outbreaks, and detect the emergence of new flu strains. This information helps guide public health responses, like vaccination campaigns and resource allocation. The goal is to understand how the flu is circulating in communities, predict potential increases, and protect public health by informing timely interventions.
