The corona virus first developed in Wuhan China (temperet climate). But now it has spread to the tropics (for example Brazil, Indonesia and countries in Africa). Please inform whether climate influences the spread of the corona virus. Thank you
The world health organization (who) said that the climate does not affect the development and manifestation of the coronavirus in any way.
It is necessary to consider this virus as one that can be transmitted in other regions in the same way as in China. At the moment, there is no reason to believe that the virus can manifest differently in different climatic conditions.
The judgment is very soon. But considering world map of spreading virus at Apr 14, 2020 ( https://www.kff.org/glbal-health-policy/fact-sheet/coronavirus-tracker/ ), you see that in the moderate climates in northen hemisphere , virus has a high intensity, and the intensity is not high at very hot climates(southern hemisphere) and very cold climates(Rusia, Canada ). May be this region of the world(moderate climates) is the optimal ecological nich for covid_19.
Arguably, a virus is non living thing as long as it stays outside the host body. We still do not have any proof to directly correlate the spread of virus with the climate, as it’s spread through direct contact. But it’s clear that the persistence and rate of multiplication is very low in tropics compared to those with temperate climate.
