The Global Influenza Programme (GIP) provides 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.

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.

Overview It is recommended that quadrivalent vaccines for use in the 2022 southern hemisphere influenza season contain the following:

Antigenic and genetic characteristics of zoonotic influenza A viruses and development of candidate vaccine viruses for pandemic preparedness in the 2026-2027 northern hemisphere influenza season

This WHO Clinical practice guideline for influenza is an update and expansion from the previously published WHO guideline on the clinical management of patients with severe influenza or at risk of severe influenza. These updated guidelines provide recommendations on the management of both severe and non-severe influenza and also includes recommendations on the use of antiviral medications to ...

Influenza, or the flu, is both a seasonal and a pandemic virus. Every year, mainly during the winter season, seasonal influenza infects as many as 1 billion people. This makes it one of the most common infectious respiratory viruses, after the common cold. Thankfully, the WHO Global Influenza Surveillance and Response System, or GISRS, monitors what viruses are circulating and twice a year ...
