Global respiratory virus weekly updates
Surveillance data for influenza, respiratory syncytial virus (RSV) 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, RSV, SARS-CoV-2, and other respiratory virus activity.
