This is the first confirmed case of reinfection in the US. The two infections in this one patient occurred six weeks apart.
Reinfections are rare – there are only five such cases documented worldwide. But much is still unknown about how or why this happens. The Centers for Disease Control and Prevention currently advises that those who have recovered from Covid-19 generally appear to be protected from reinfection for three months – but this newly documented case bucks that expectation.
A 25-year-old man in the U.S. state of Nevada has contracted the coronavirus on two separate occasions, a study in the Lancet Infectious Diseases journal showed, with the patient becoming seriously ill following the second infection.
It is the first confirmed case of a U.S. patient becoming re-infected with Covid-19, and the fifth known case reported worldwide.
The resident of Washoe County, who had no known immune disorders or history of significant underlying conditions, required hospital treatment on testing positive for Covid-19 for the second time.
He has now recovered, though the case raises further questions about the prospect of developing protective immunity against the coronavirus.
One out of 8 million US cases is pretty good odds. There's always that one weird person with a genetic defect in their antibody-making genes, or some such thing. They should sequence his DNA to see if that's the case. It could prove helpful in fighting it.Hey President Trump, want to pay this man a visit?
Coronavirus: First case of Covid-19 reinfection confirmed in the U.S.
My county went back to in-person classes this week. Predictably one high school has already had to go back to virtual because they had six positive cases.
ETA: Though a vaccine, if and when one becomes available, doesn't mark an end to anything:Van-Tam gave a briefing to MPs on Monday afternoon in which he said: “We aren’t light years away from it. It isn’t a totally unrealistic suggestion that we could deploy a vaccine soon after Christmas. That would have a significant impact on hospital admissions and deaths.”
The first vaccines will be given to the elderly and vulnerable and to vaccinate those most at risk will take several months. Most people will not be given the jab.
An MP who attended another briefing with Van-Tam said he was “very bullish about the third stage AstraZeneca results, which he expects between the end of this month and the end of next”. The MP said: “Van-Tam expects it to protect the elderly and vulnerable. He gave us to understand that it stopped the virus ‘shedding’ in the young. He said he would expect vaccination to start in January.”
It's over when it's over. Complicating factors:ETA: Though a vaccine, if and when one becomes available, doesn't mark an end to anything:
Just like the Black Death, influenza and smallpox, Covid-19 will affect almost every aspect of our of lives – even after a vaccine turns upwww.theguardian.com
