Global Influenza Surveillance Network

The Global Influenza Surveillance Network is an international system that monitors flu activity worldwide. It collects data from laboratories and health agencies to track the spread and types of influenza viruses circulating in different regions. This information helps in early detection of outbreaks, understanding how the flu evolves, and informing the annual vaccine formulation. By sharing data across countries, the network supports coordinated responses to prevent and control influenza outbreaks, ultimately protecting public health on a global scale.
