On the fire department that I retired from 11 people tested positive. 10 had no symptoms; 1 had symptoms so mild that he was still coming into work. I think that your 15% figure is off by somewhere around 10 times. Maybe you should get a job as a global warming modeler.
How many were healthy and strong and vigorous with no underlying issues? How many people did the one with very mild symptoms infect before he discovered that he too had the virus? How many were given Hydroxy during the illness?
It seems you and I could be co-workers as global warming modelers.... But I’ll also keep my day job as an ICU RN and hoping to dodge “the bullets” from the covids patients I work with as they come in sicker than crap...but fewer in the numbers we had been expecting...
