My daughter has a friend who caught COVID in March. After a few weeks he was better and tested negative, and seemed to be over it. In the past week, he has symptoms and has tested positive again. This brings up 3 possibilities, none of which are good: - You can catch COVID more than once. There is no immunity.
- Even after you are "better" and test negative, you still may be carrying enough to get sick and/or infect others.
- The tests aren't accurate, and a negative test doesn't mean you don't have it.
This is just one incident, but it is disturbing.
BTW, he is 31 and was healthy prior to this.

I have read reports on antibody counts after infection which point to widely varied consequences of COVID infection; some people seemed to obtain higher counts than others. There may be variations in the degree of immunity individuals obtain as a result of infection.

Apparently, it is not just my daughter's friend. --------------- “Wait. I can catch Covid twice?” my 50-year-old patient asked in disbelief. It was the beginning of July, and he had just tested positive for SARS-CoV-2, the virus that causes Covid-19, for a second time — three months after a previous infection. While there’s still much we don’t understand about immunity to this new illness, a small but growing number of cases like his suggest the answer is “yes.” Covid-19 may also be much worse the second time around. During his first infection, my patient experienced a mild cough and sore throat. His second infection, in contrast, was marked by a high fever, shortness of breath, and hypoxia, resulting in multiple trips to the hospital. Recent reports and conversations with physician colleagues suggest my patient is not alone. Two patients in New Jersey, for instance, appear to have contracted Covid-19 a second time almost two months after fully recovering from their first infection. It is possible, but unlikely, that my patient had a single infection that lasted three months. Some Covid-19 patients (now dubbed “long haulers”) do appear to suffer persistent infections and symptoms. My patient, however, cleared his infection — he had two negative PCR tests after his first infection — and felt healthy for nearly six weeks.

mhb, that scenario that Ackerly suggests is as bad as it can get. And if true, will likely get us all sooner or later.
