Surveillance recommendations for Member States in the post-pandemic period

Geneva, 12 August 2010

Publication details

The purpose of surveillance in the post/pandemic period is to provide information that will enable timely epidemic or pandemic detection, inform health policy decisions and influenza management strategies, and guide influenza vaccine development and prioritization.

Four key surveillance objectives include:

  • early detection of unusual events that might indicate a shift in the severity or pattern of disease associated with influenza, or emergence of a new virus;
  • establish and monitor baseline rates of severe respiratory disease, including monitoring the severity, disease burden, and impact of influenza;
  • describe and monitor vulnerable groups at highest risk of severe disease;
  • detection of antigenic or genetic changes in circulating viruses or the appearance of antiviral resistance.
