Every few decades a new, and potentially deadly, influenza virus emerges and spreads worldwide. These events – influenza pandemics – are a threat all countries need to prepare for. The Preparing for Pandemics channel brings together courses on various aspects of preparedness, including surveillance, public health measures and risk communication during a pandemic. You can learn the basic epidemiology and virology of influenza. You can learn the differences (and similarities) between zoonotic influenza, seasonal influenza and pandemic influenza. And you can get informed about how WHO, Member States, industry and other stakeholders work together in the Pandemic Influenza Preparedness (PIP) Framework.
