Question normal

News that the first Covid death was established by tissue exams from autopsy to be in California on Feb 6 pushes back the date of entry into this country. Given the number of lobectomies and other procedures where lung tissue is taken for various reasons, why can’t we test tissue from December 2019 to see if the virus was circulating in this country then? We’ve all heard that there were people suffering from dry cough and other symPtoms that took them a couple of weeks to shake (happened to me in mid-January—I was coughing constantly and it got so bad I could not get to sleep for 2 nights). If it was here that early, then it is probably even more widely circulated than we currently think . Also, since we didn’t have the overwhelming numbers then that we have now, is it possible it mutated?
