What happens if Covid-19 symptoms don’t go away? Doctors are trying to figure it out.

In late March, when Covid-19 was first surging, Jake Suett, a doctor of anesthesiology and intensive care medicine with the National Health Service in Norfolk, England, had seen plenty of patients with the disease — and intubated a few of them.

He pushed through it, continuing to work for five days until he developed a dry cough and fever. “Eventually, I got to the point where I was gasping for air literally doing nothing, lying on my bed”…

It’s now been 14 weeks since Suett’s presumed infection and he still has symptoms, including trouble concentrating, known as brain fog. (One recent study in Spain found that a majority of 841 hospitalized Covid-19 patients had neurological symptoms, including headaches and seizures.) “I don’t know what my future holds anymore,” Suett says…

Scientists are still learning about the many ways the virus that causes Covid-19 impacts the body — both during initial infection and as symptoms persist. One of the researchers studying them is Michael Peluso, a clinical fellow in infectious diseases at the University of California San Francisco, who is is currently enrolling Covid-19 patients in San Francisco in a two-year study to study the disease’s long-term effects…
