What Is ‘Long’ COVID?
Approximately 80% of patients infected with COVID-19 develop mild to moderate symptoms (fever, dry cough, fatigue) and recover within a few weeks. The other 20% develop more serious symptoms, including severe inflammation, shortness of breath, confusion, persistent pain or pressure in the chest, and organ damage. Severe cases often require hospitalization. For those admitted to intensive care units, stays of three weeks or more are common.
In the course of the pandemic, it has become clear that there is a large and growing group of people who continue to deal with prolonged, lingering symptoms of COVID-19 long after their original illness and well beyond their “normal” course of recovery. This is sometimes referred to as having “Long” COVID or to being part of the patient population referred to as “long haulers.” Research suggests that approximately 30% of patients who recover from COVID will end up developing long-haul symptoms.

With any COVID-19 infection, lying sick in bed at home or in the hospital for an extended period can lead to significant weight loss, weakness, cardiopulmonary deconditioning, and fatigue. Prolonged bedrest can also result in a decrease in muscle mass due to limited use.
Recovery from COVID-19 can be a steep physical and mental grind. Patients are reporting substantial functional challenges, such as lingering lung problems, muscle weakness, and cognitive concerns ranging from "brain fog" to delirium. Even patients with initially mild COVID can develop long-haul symptoms.
