Long-Haul COVID
Avindra Nath
Abstract
Modern medicine has faced its biggest challenge from the smallest of organisms. It is becoming increasingly apparent that many patients who recovered from the acute phase of the SARS-CoV-2 infection have persistent symptoms. This includes clouding of mentation, sleep disturbances, exercise intolerance and autonomic symptoms (table 1). Some also complain of persistent low grade fever and lymphadenopathy. Although there are no peer reviewed papers at the moment on these patients, many news articles have been written about this phenomenon1–4 and there are Facebook groups with several thousand patients describing these symptoms. They call the illness, “Long-Haul COVID” or “Long-tail COVID.” Many of these patients are health care workers who had massive exposure to the virus early in the pandemic and describe having symptoms for “100+ days.”5
