Hot Weather also implies plenty of sun. Given the high Negro population in SC, if Vitamin D is a critical factor for higher death rates in dark skinned people, then hot weather/sun would also see a reduction in Covid cases. So definitely be aware an increase is a possibility in Winter if Vitamin D is a factor. Also people eat more high C foods in summer and fall

GARY CRAMERI: We’ve been looking in bats for about the last eight years looking for this particular virus and although a lot of groups across the world have been, this particular virus can infect humans directly, as the original SARS virus could.

“For Caucasians, blood levels of 25-hydroxyvitamin D are a pretty good proxy for how much of the bioavailable vitamin they have. But not for blacks. That’s because blacks have only a quarter to a third as much of the binding protein, Thadhani says. So the blood test for the 25-hydroxy form is misleading.
His study finds that because of those lower levels of the protein, blacks still have enough of the bioavailable vitamin, which explains why their bones look strong even though the usual blood tests say they shouldn’t.”
“Everyone who came out of Africa had the ancestral genotype associated with lower vitamin D-binding proteins,” Thadhani says. “When humans moved to areas with less sunlight, a different genotype evolved. The further north they went, the more people needed reserves of vitamin D. So D-binding protein levels went up.”
And that genetic difference in vitamin D-binding proteins is what researchers have finally figured out.”
