During the early stages of the Covid-19 pandemic, reports emerged that persons who had been infected with SARS-CoV-2 were having lingering health problems. Such long-term issues were collectively referred to as “long Covid” and were reported to affect nearly every organ system.¹ The cardinal features of long Covid include fatigue, dysautonomia (or postural orthostatic tachycardia syndrome), postexertional malaise, and cognitive difficulties that are colloquially referred to as “brain fog.”
