There is something very interesting about the outbreak in Italy. The region of Italy where the outbreak is centered has a high population of Chinese immigrants and guest workers who provide much of the labor for the garment industry. Are the Italians who are becoming infected and seriously ill really Chinese? Not politically correct to ask or speculate. However it may very well be that Caucasians and Africans are not as susceptible for infection or serious disease as are genetic Asiatics. That is not a narrative that WHO wants propagated.
Genetic susceptibilities of a given population determine where and to what extent any given epidemic will extend. It would appear that some Persians have the genetic susceptibility to COVID-19.
I found it interesting, too, to read yesterday of a sudden, ‘blow up’ of cases in Italy. Weird.
a case of genetics affecting people differently is found in (san joaquin) Valley Fever a fungus that gets into the lungs..some can loose limbs others can perish most get over it without medication..race is a factor.
Also Italy is the biggest producer of rice in the EU. That area of Italy is where almost all the rice is grown so there are lots of farm laborers there.
