Movement of persons in or out of these areas has implications for viral disease. Flu, Ebola, Covid-19, Keshan disease and Kashin Beck disease are the ones we know amount so far.
Italy ost 475 people in one day to Covid-19 on march 18, 220, but this region of Italy is low in soil selenium levels.
Italy has the variant of the virus that is endemic to low selenium areas and is more pathogenic. Iran does too and has the same soil.
99% (figures published today) of the people who died had something else wrong with them.
North America has the other varian of the virus that is not as pathogenic.
Low selenium is known to mutate viruses into more pathogenic forms: it's now for flu and coxsackie virus at the very least and we can add CoV to the list now. They're called the S and L forms.
Keep in mind only one region of China was hard hit, the part that has no soil selenium to speak of. The get worse outbreaks of viral diseases ans plague (which is also inhibited by selenium) as well as Keshan disease and Kashin Beck disease.
