I know of one young guy that was Corvid-19 positive. It came on as a mild cold and was gone in three days. He was retested three times over four weeks before the fourth test showed him as negative. One case that shows up in the numbers as four cases of Corvid. His parents have been tested multiple times and are still are showing as positive. I figure between his parents add they added 8-10 additional cases in the state and county numbers.
