Most COVID-19 survivors have symptoms 6 months on, review finds

A systematic review of 57 studies involving more than 250,000 COVID-19 survivors reveals that 54% still had at least one symptom 6 months or more after initial diagnosis or release from the hospital. In the review, published today in JAMA Network Open, a team led by Hershey (Pennsylvania) Medical Center researchers searched the literature from December 2019 through March 2021 for studies on persistent COVID-19–related symptoms diagnosed using lab results, radiologic findings, or clinical signs or symptoms at or after 1 month.
