There’s a lot of information out there about how governments, health professionals and the general public should respond to the COVID-19 pandemic. WHO has published guidance and advice every step of the way.
Since January 2020, WHO has published more than 100 documents about COVID-19. Of these, more than half are detailed technical guidance, on how to find and test cases, how to provide safe and appropriate care for people depending on the severity of their illness, how to trace and quarantine contacts, how to prevent transmission from one person to another, how to protect health care workers, and how to help communities to respond appropriately.
This page at the WHO website provides links to these different subjects. One particular area of interest is the free video training that WHO has produced.
As of July 2020, more than 3.7 million people had enrolled in the OpenWHO platform, which has more than 100 free online courses about COVID-19 in 31 languages, including courses for health workers and other frontline responders.
