The WHO’s Global Influenza Programme (GIP) provides global standards for influenza surveillance. In addition GIP collects and analyzes virological and epidemiological influenza surveillance data from around the world. The regular sharing of quality influenza surveillance and monitoring data by countries allows WHO to:

  • provide countries, areas and territories with information about influenza transmission in other parts of the world to allow national policy makers to better prepare for upcoming seasons;
  • describe critical features of influenza epidemiology including risk groups, transmission characteristics, and impact;
  • monitor global trends in influenza transmission; and
  • support the selection of influenza strains for vaccine production.
