>>11603605That's not summertime. It's summertime sunlight exposure during mid-day. If you can get a sun burn, the UV is enough to destroy most pathogens.
The problem is humans don't usually get in dense clusters out in the open anyway. We do it indoors where there's AC and no UV, where covid can survive for a day or more.
And that antibody sampling has yet to be peer reviewed. Like most of the garbage floating around, it's pure hopium. In reality the antibody test has a high false positive rate. You'll show positive for having recently had any coronavirus, including the relatively benign ones partly responsible for "the common cold".
