I think the symptomatic should be quarantined.
Mostly, I find it quite ironic that folks in the medical community, who want to isolate smokers, don’t want to isolate themselves.
You have a better chance of getting ebola from one of these folks sneezing in your face than getting cancer from a whiff of smoke outside.
That's obvious, and too late. The USDA quarantines every horse that comes into the country to protect against certain diseases that would destroy that industry. Waiting until symptoms appear is way too late, as by that time the other horses stable together with the first are in trouble.
Dogs, as well as fruit bats, can carry the ebola virus. Heaven help us if some ebola patient falls over in a park and the local feral dogs check it out. Or a friendly dog simply licks the face of somebody sweating from a slight fever.
It's just not as simple as the CDC/NIH keep insisting.
