I think some people don't get the virus. one of my boys got it sometime ago and another of my sons live in the same house and he never got it.
Herd many stories like that.
and im sure there are many, many people who get it without many symptoms
remember the whole "a-symptomatic carriers" fear mongering?
yeah, those people should be included when they calculate the death rate, in order to get an honest appraisal of the disease
