“I was a little bit in denial. It can’t be that. I can’t get it twice.” Nurse Anitra Hines thought she was done with COVID after her first bout -- until it came back again, and hit her even harder than before.
About a month later, she tested negative and felt well enough to return to work. She even felt safer.
Anitra wanted to drive herself, but her mother called an ambulance. After she walked down two flights of steps to meet the ambulance crew, the oxygen level in her blood had dropped into the low 60s. Normally, blood oxygen is close to 100%. Wright, 29, a photographer in Nashville, caught COVID in March after taking a trip to New York. He ran aWright was feeling better. He’d gone grocery shopping -- always in a mask -- and had seen a few friends from a safe distance.
Experts are puzzling over these two-timer cases, too. There’s been no comprehensive study of cases like this, and no one knows yet whether reinfection is possible, especially so soon after someone has recovered. But what about cases like Hines’s and Wright’s, where symptoms return along with a second positive test? Could they have caught the virus a second time?
“You can mount an immune response that clears an infection the first time. It’s really whether you develop that persisting memory that gives you protective immunity,” says Farber.Early evidence suggests that some people might not.
