My patient caught Covid-19 twice. So long to herd immunity hopes?
 h/t Hot Air[Vox] - "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. I wonder, could this explain an increasing number of young people who have a symptomatic covid-19. That is, they've had an asymptomatic one already 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. Daniel Griffin, a physician and researcher at Columbia University in New York, recently described a case of presumed reinfection on the This Week in Virology podcast. 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. Can we have a surprise meter? Because you know, based on our previous experiences with common cold, nobody would expect this in a million years. So you're admitting it's like the common cold? *snicker* Posted by: g(r)omgoru 2020-07-14 |
