[quote=Coronita][quote=The-Shoveler]There are likely Huge numbers of unreported positive cases.
We need a test for covid-19 anti-bodies more than the other way around at this point.
We may be much closer to herd immunity than we think.
Likely Covid-19 has been circulating in SoCal since December.[/quote]
I mentioned this earlier. My colleagues at my old company went back and forth between here and china all during december, and towards early january all came down with something worse than a flu, but their flu tests all came back negative.
104-105 fever, dry cough, difficult breathing. 2-3 weeks later, for them it passed, and some of their colleague got the same thing. Back then in early January, there was no coronavirus test here in the states as generally in the states we were clueless about the severity of this virus, partly due to China’s denial there was a problem. Most likely those colleagues had the coronavirus and gave it to everyone else in that group and their respective families. Now, in March, they asked if they can get tested, but there isn’t a way here in the states to test for antibodies, and even if there were, it too much time might have already passed.[/quote]
The antibodies should persist for some time. Some studies show the SARS antibodies persist for at least 12 years.
