Many people who have COVID-19 make a full recovery and return to their baseline state of health; however, some people have symptoms or other sequelae weeks or months after initial SARS-CoV-2 infection. These heterogeneous symptoms were the subject of the virtual “Workshop on Post-acute Sequelae of COVID-19” hosted on Dec. 2 and 4, 2020, by the National Institute of Allergy and Infectious Diseases (NIAID), in collaboration with other institutes and centers of the National Institutes of Health. A paper published recently in Annals of Internal Medicine describes the workshop. Over 1,200 registered participants including researchers, clinicians, and affected community members discussed what is known about sequelae after COVID-19 and the knowledge gaps that need to be addressed in future research.
