Talmudic Question #97

by Welkin Johnson

What is the minimum set of adaptations that HIV would have to acquire in order to become a successful airborne pathogen like influenza?


"A formidable challenge" for the virus or for one of us to figure out Euux?

FIV is so prevalent in cats who live closely together in the wild that if it were easy for a like virus to go airborne it likly would have. Thus it might be difficultl and also, after learning to floatit would have to find some new receptor sites.

Maybe, the virus doesn't think it's worth all the trouble considering how much fun its current mode of infection is. Both cats and humans are more likely to give up breathing than sex.

Query --an FIV-positive mom cat had 4 kittens two of whom tested positive and two negative. How come all four kittens didn't acquire the virus?

a formidable challenge.
