"Novel corona" [sic] doesn't generally "kill." The vast majority of deaths are caused by the virus in cahoots with other serious medical conditions, and the death rate, admittedly proving difficult to pin down, always represents a small minority of infections.

A considerable majority of common cold infections may be put down to rhinoviruses, possibly most. Human coronaviruses cause a minority of colds. A number of other virus types can also cause colds. Comment is free but facts are sacred (and easily accessible).
