Витамин Д и Ковид

Очень интересно про Ковид.
Основные факторы влияющие на распространение:

1) Number of elderly (esp. men) as proportion of population
2) Severely overweight proportion of pop.
3) Proportion of pop. with dark skin in the northern hemisphere
4) Season and climate (and thus also continent)

То есть дефицит витаминта Д.
