Introduction:
The coronavirus disease 2019 (COVID-19) pandemic paralyzed the United States, rendering thousands critically ill and ultimately killing more than 1 million Americans. Many survivors, particularly those with adult respiratory distress syndrome, required prolonged rehabilitation. Many more people, including those who did not require hospitalization for their acute illness, presented with a host of other persistent, disabling symptoms. The latter condition was termed “Long Covid” and turned out to be the most prevalent postacute sequelae of the COVID-19 pandemic.
The symptom complex that characterizes Long Covid resembles that seen in other infection-associated chronic conditions, notably overlapping with those of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Overlapping symptoms include fatigue, unrefreshing sleep, neurocognitive dysfunction characterized by impaired executive function, exercise intolerance, fluctuating heart rate and sense of dizziness particularly in the upright position, and postexertional malaise, a signature symptom of ME/CFS. The drivers of these conditions remain unknown, and no treatments have proven effective. Data suggest that many individuals with Long Covid may return to health months or years after onset, but debilitating symptoms and unknown long-term outcomes remain in too many people. Of greatest concern is that, for some individuals, Long Covid may last a lifetime.
