Global Influenza Programme: A Checklist for Pandemic Influenza Risk and Impact Management [open pdf - 963KB]
From the Introduction: "A pandemic is the worldwide spread of a new disease. Influenza pandemics are unpredictable but recurring events that can significantly affect health, communities and economies worldwide. Planning and preparation are critical to help mitigate the risk and impact of a pandemic, and to manage the response and recovery. Influenza pandemics occur when a new (novel) influenza virus emerges against which people have little or no immunity, and spreads around the world. Influenza viruses that have caused pandemics in the past have typically originated from animal influenza viruses that have mutated to new forms able to infect humans. To prevent or delay potential influenza pandemics, close coordination between animal and human health sectors is needed, to detect and control these novel viruses in animal populations before they are able to infect human populations."
