Influenza pandemics are unpredictable but recurring events that can have severe consequences on societies worldwide. This revised WHO guidance publication on pandemic influenza preparedness and response acknowledges that pandemic preparedness is centered around health sectors planning but must also be broader. WHO therefore advocates a "whole-of-society" approach to sustainable and ethical pandemic preparedness while focusing in more detail on the role of the health sector. The roles of WHO and national governments are outlined to create a better understanding of how health and non-health sectors, both public and private, all contribute to pandemic preparedness.--Publisher’s description
