Unlocking the mysteries of Long Covid

‘A growing number of clinicians are on an urgent quest to find treatments for a frighteningly pervasive problem. They’ve had surprising early success...

‘The unlucky remainder—more than 90 percent of the patients the center has seen—was a puzzling group “where we couldn’t see what was wrong,” Chen said. These tended to be the patients who had originally had mild to moderate symptoms. They were overwhelmingly women, even though men are typically hit harder by acute COVID‑19. (Acute COVID‑19 refers to the distinct period of infection during which the immune system fights off the virus; the acute phase can range from mild to severe.) And they tended to be young, between the ages of 20 and 50—not an age group that, doctors had thought, suffered the worst effects of the disease. Most of the patients were white and relatively well-off, raising concern among clinicians that many people of color with ongoing symptoms were not getting the care they needed.

‘These patients’ tests usually showed nothing obviously the matter with them. “Everything was coming back negative,” says Dayna McCarthy, a rehabilitation-medicine physician and a lead clinician at the center. “So of course Western medicine wants to say, ‘You’re fine.’ ”

‘But the patients were self-evidently not fine. An international survey by Patient-Led Research for COVID‑19, one of various groups drawing attention to persisting problems, asked nearly 3,800 patients with ongoing illness to describe their symptoms. A significant number—85.9 percent—reported having relapses in the months after their initial infection, usually triggered by mental or physical exertion. (Not all patients in this group had confirmed cases of COVID‑19, given that tests were hard to come by last March and April.) Many patients were experiencing severe fatigue and brain fog. Other patients suffered from chest tightness and tachycardia—a condition in which the heart beats more than 100 times a minute—when they stood up or walked. Others had diarrhea and lost their appetite; some had terrible bone pain. Nearly a quarter said they were still unable to work; many had gone on disability or taken medical leave. Patient groups of COVID‑19 “long-haulers” were springing up on Facebook and elsewhere online, where people shared data and compared notes about what they began to call “long COVID.”’
