If a test result is positive, it means that a reaction in a test tube, artificially forced to give a binary result, gave a positive result. Something reacted with something. In most cases is will be the antibody reacting with the correct antigen, but false positives are almost a law of nature when working with antibodies, from physichochemical artifacts to degrading reagents to cross reactions with other coronavirues.
Still, yes, most of those positives will be real and yes, for every PCR positive there seems to be a good few people that had an asymptomatic or mild disease and that now are, most likely, inmune. Let's hope they are many, many more than we think, because then and only then we are on our way to herd immunity.
I don't want to even imagine reaching next winter with less than 5% of the population immunized.
I guess this shows that I live in the northern hemisphere, because that is exactly what is coming to the southern hemisphere. /Holds breath/
This. And remember it is called Covid 19 because there have been many of a similar strain to i, including SARS and MERS and probably several we did not even recognise as anything other than another flu. This could even be a mutation of something that has been in animals for many years and not been powerful to notice when it originally made the jump, but is still about. How often do you hear of someone having an unspecific virus? there are many we do not classify even if detected.
