Shortly after the COVID-19 pandemic onset, emerging studies showed that a considerable proportion of patients with COVID-19 might exhibit sustained postinfection sequelae. This condition has been defined by a variety of names, including<unk>  or<unk> -haul COVID, and post-COVID-19 condition. The absence of a universally standardized terminology has made characterization of the epidemiology, risk factors, clinical characteristics, and potential treatments options difficult. Symptoms may occur as an unpredictable combination of respiratory, cardiovascular, urological, neurological, and/or gastrointestinal manifestations. However, the most common symptoms include fatigue, dyspnea, and cognitive dysfunction (known as brain fog by the patients). Symptoms may begin following initial recovery from an acute COVID-19 episode or may persist from the initial acute episode. Symptoms might also fluctuate or relapse over time.
