> Although they are thought to be only about half as infectious as individuals with confirmed COVID-19, individuals with undetected infections were so prevalent in China that they apparently were the infection source for 86 percent of confirmed cases. Figuring out how to manage this risk so we can return to society / open venues at a much lower risk of infection (while not giving all of our data to the government) is a challenge with which maybe some of this site's audience could assist.
