I am watching Africa, Asia and South America numbers to see if they explode in the next week. Since ambient temps don’t seem to be an issue for this virus then there has to be a reason rates of infection are lower in known malaria regions.
One MORE time. People who live in those places don’t take the drugs.
For Influenza, it may be the seasonal rise in relative humidity, rather than increased air temperature, which impedes spread of the virus. Not because the RH directly affects the virus, but because of the effects of dry air upon the nose, throat, and upper lung tissues making them more susceptible to the flu virus.
The again, the Coronavirus is a different beast—temp and humidity may not have any bearing upon rate of infection.
