Is Qatar hot and dry? I think heat with humidity are more likely to dampen the spread compared to just heat
That's odd to me because I associate warm and wet with uncleanliness and festering cesspools.
Anyway apparently hot and wet is good for bacteria, but cold is better for viruses. The bit that made it click for me is that viruses aren't metabolising anything outside of the host-cell, so the best a virus can hope for is to not be destroyed -- and cold is a better preservative.
I'm still not sure whether hot and humid is better than hot and dry though? I think I read that hot and dry is worse, because it increases evaporation.
That's not true for every type of virus, but it is true for corona viruses.
