Anecdotal reports in a small number of cases =/= a common symptom that will affect a significant number of patients.Probably not but its to early to tell...since its novel. There are reports of organ damage and renal failure. The Reaction to it however could end the human race for sure.
Two entirely different groups of viruses.If somebody had said HIV AIDS wasnt a big deal because it caused no symptoms in anyone at all..they only had to wait 6-7 years.
Do you have a source for this?As far as testing goes. Most of your positive tests are probably other CoronaViruses and NOT covid19. But there is a deadly form of SARS going around...their is no doubt.
I have heard that other coronaviruses may skew the data somewhat but not enough to account for "most positive tests" even remotely.
