Pulmonary Sequelae of Coronavirus Disease 2019

Severe acute respiratory syndrome coronavirus 2, the infectious agent that causes coronavirus disease 2019 (COVID-19), can infect multiple organ systems triggering an inflammatory response resulting in abnormalities in cellular and organ function. This can result in multiple symptoms and associated functional limitations. Respiratory symptoms in acute COVID-19 and in post-acute sequelae of COVID-19 (PASC) are common and can range from mild and intermittent to severe and persistent, correlating with functional limitations. Although the long-term pulmonary sequelae of COVID-19 infection and PASC are not known, a considered rehabilitative approach is recommended to yield optimal functional outcomes with a return to pre-morbid functional, avocational, and vocational status.
