Evolution can favor mild viral infections, thus possibly making East Asians more susceptible to Covid19

…I [have] argued that coronaviruses have coevolved with the Chinese population, to the point of developing a commensal relationship. A few points:

–  Such viruses include the common cold and are normally mild in their effects.

– Repeated coronaviral infections of lung tissue may actually help increase resistance to more serious pulmonary infections, like tuberculosis, pneumonia, and the Spanish flu of 1918—which curiously spared China. 

– Chinese lung tissue would thus facilitate coronaviral infections as a sort of routine vaccination. 

– If this is true, modern medicine has inadvertently made the Chinese population particularly vulnerable to deadly diseases like the Wuhan coronavirus by reducing the prevalence of milder pulmonary infections. (Coevolution with the plague)

This is the best essay I have seen on the topic of are or why are East Asians more susceptible to Covid19.

Nowadays, the topic of racial differences is avoided like the plague. If Covid19 is more harmful to East Asians (Mongoloids) due to ACE2 receptor differences in the lungs, no one benefits from hiding that information.
