Influenza surveillance
Influenza surveillance is the systematic monitoring of flu activity in populations. Health authorities collect data on flu cases, symptoms, and lab-confirmed infections from healthcare providers and laboratories. This information helps track the spread of the virus, identify its strains, and assess vaccine effectiveness. By analyzing trends and patterns, public health officials can make informed decisions about vaccination campaigns, public health responses, and resource allocation. Ultimately, influenza surveillance plays a crucial role in controlling outbreaks and protecting public health.
