Having trawled through all this; I can't believe that no-one picked up on roopower's post at about 9.58 this morning. It mentioned, quietly, the issue of Vitamin D. As is happens, we were visiting our local surgery yesterday to have Mr. J2's dressings changed and I mentioned to the nurse several articles I had read which cited the lack of vitamin D amongst BAME sufferers. She knew that dark skins absorb less vit. D (this all started because we commented on her 'gardening tanned' arms) and we had quite a discussion. Vit. D levels are higher in northern populations - which seek the sun - she thought that Swedes had the highest level. Mediterranean types e.g.. Spanish, avoid the high sun a lot and have a darker skin and African skins do not allow much vit.D to be made through sunlight.
Then today I read an article on the front page of the Telegraph, headlined 'Getting some sunshine can protect against transmission', scientific adviser suggests.
Add this into the mix, please ---- and where the racial discrimination domes from, I don't know. Lifestyles and genetics also count of course.
