World Health Organization
In 1947, WHO’s Interim Committee recognized the importance of Influenza and started a globally-coordinated effort for its surveillance, study and control. This led to the beginning of the Global Influenza Program (GIP) and the Global Influenza Surveillance and Response System (GISRS). The 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.
