If this virus is like sars, it doesn't seem to transmit well in hot environments (which is why sars just went away during summer) at least it will not transmit as well in Africa.
Haven’t there been multiple local transmissions in Singapore, which is pretty warm right now?
Yes, but one would assume there is a lot of AC in Singapore.
Likely blasting full power in every large building. (It's really pretty much the case in every hotel / conference room) Which helps the air to mix where people meet.
