[Expanding the pandemic influenza preparedness framework to the epidemic of COVID-19].

On March 11, 2020, WHO officially declared that COVID-19 had become Pandemic. As of March 31, the epidemic had affected more than 178 countries and regions, with more than 780 000 confirmed cases. The Pandemic Influenza Preparedness Framework for the sharing of influenza viruses and access to vaccines and other benefits (the 'PIP Framework' or 'Framework') is an international arrangement adopted by the World Health Organization in May 2011 to improve global pandemic influenza preparedness and response. Since the transmission route and transmission capacity of COVID-19 are similar to that of influenza A (H1N1) in 2009, which conforms to the basic elements of "human pandemic", and the epidemic scale has exceeded that of influenza A (H1N1)， it is probable to incorporate COVID-19 epidemic response into PIPF, and at the same time to verify and improve PIPF in practice. It is recommended that WHO, other international organizations and relevant countries make full use of the PIPF system to respond to the epidemic and better coordinate national actions at the global level. At the same time, China should also make the planning and deploy of domestic epidemic prevention and control and international epidemic cooperation under the framework.
