Experts Discuss Long Covid Risks and What Remains to be Learned

Much has been said about the long-term effects of Covid-19 on people who contracted the virus, but whose symptoms continue to persist long after the initial infection has passed. The World Health Organisation (WHO) addressed questions around the implications of Long Covid hosted by WHO Social Media Manager Aleksandra Kuzmanovic, with Dr. Maria Van Kerkhove, WHO Technical Lead on Covid-19, and Dr. Janet Diaz, Clinical Management Lead, WHO Health Emergencies Programme.

The National Library of Medicine defines Long Covid as "coronavirus disease 2019 (Covid-19) related symptoms that persist more than 28 days from the onset of acute infection". It estimated that 10% of people with acute Covid-19 infections will develop Long Covid symptoms. According to the Centers for Disease Control (CDC), post-Covid conditions are a wide range of new, returning, or ongoing health problems that people experience after first being infected with the virus that causes Covid-19. While most patients recover between several days and two weeks after infection, some may find symptoms up to four weeks which is when a post-Covid condition may be identified.
