Global Influenza Programme
We provide Member States with strategic guidance, technical support and coordination of activities essential to make their health systems better prepared against seasonal, zoonotic and pandemic influenza threats to populations and individuals.
Respiratory viruses
Surveillance data for influenza and SARS-CoV-2 are shared with WHO through the Global Influenza Surveillance and Response System (GISRS). Each week, these data are reviewed and analyzed by the Global Influenza Programme to provide a global overview of influenza, SARS-CoV-2, and other respiratory virus activity.
