The good thing about coronaviruses is even if they do spread from person to person they usually respond well to quarantine because the infectious period is almost always concurrent with the symptomatic period.
Bats eat mosquitoes which carry plagues, but but can themselves carry rabies, possibly the deadliest virus known to mankind (when untreated), as well as ebola, and apparently SARS as well now. Hmmm.
Nothing is like rabies on the deadly scale, not even ebola. The highest mortality rate ever reported for an ebola epidemic was 90%, but it is usually more in the high 50% range. Rabies has a 100% mortality rate, but without the epidemic. I still think smallpox was probably the scariest as far as epidemics go because the mortality rate is nothing to scoff at, the disease is horrible, and the rate of spread was off the charts.
Rabies is a disease of mammals and any mammal could potentially have it, but in the US most people do contract rabies from bats.
About 1% of bats carry rabies. Raccoons have a higher incidence .
And by the by ,cats carry the corona virus .It's harmless in its initial form ,and they just carry it . If it mutates,they get FIP .Certain vaccines precipitate conversion of the virus . It's why most feline vaccines are dangerous .Not all ,but many will cause corona virus conversion .
Big cats get it too.It can convert on its own,usually in the presence of toxins .Bug sprays ,other toxic materials . FIP is 100% fatal .There has never been a cat to human transmission ,but I'm sure some idiot in a lab coat will claim its occurred ,sooner or later .
I have heard of FIP being cured with homeopathy ,but only under 24 hour supervision ,which is usually not possible .
