Global influenza surveillance has been conducted through WHO's Global Influenza Surveillance and Response System (GISRS) since 1952.

GISRS is a system fostering global confidence and trust for over half a century, through effective collaboration and sharing of viruses, data and benefits based on Member States’ commitment to a global public health model.

The mission of GISRS is to protect people from the threat of influenza by continuously functioning as a:

  • global mechanism of surveillance, preparedness and response for seasonal, pandemic and zoonotic influenza;
  • global platform for monitoring influenza epidemiology and disease; and
  • global alert for novel influenza viruses and other respiratory pathogens.


GISRS currently comprises institutions in 115 WHO Member States:
