Several doctors and health care workers in the UK have died as the result of Covid-19.
Is it a coincidence they they are all African and Middle-Eastern by birth?
Such ethnicity in the UK is well-recognised as being associated with very low blood levels of Vitamin D, by virtue of skin pigmentation, sun avoidance, and dietary practice.
It is well-established that Vitamin D is a powerful mediator of immunity, in particular T-cell activation. The gene-activating pathways of this are well-defined.
Unfortunately this vital role of Vitamin D does not appear to be well-known and it does not appear to have been mentioned by the medical-scientific advisors to the UK government. This is despite that fact that greatest location of Covid-19 deaths in Europe is the Lombardy plain in northern Italy, this having the greatest level of atmospheric pollution in Europe. Atmospheric pollution has been of historic as well as current importance in blocking the penetration of sunlight to ground level, thereby inhibiting Vitamin D synthesis in the skin. It is now the end of the winter in the northern hemisphere; we know that "flu" occurs mainly in the winter, when immunity is low because of low sunlight energy with the sun being low in the sky (or being thick cloud).

If we wish to improve immunity and thus diminish the impact of Covid-19, we have a simple and immediately available answer – take vitamin D supplement in a dose of 2,000 units per day and increase exposure to the sun (avoiding sunburn).
We must not let the deaths of these doctors and healthcare workers fail to alert us to what should be obvious to medical scientists.
Those who have died are as follows:
Dr Adil El Tayar
Organ transplant surgeon St Mary’s Hospital & St George’s Hospitals
D. Amged El-Hawrani
ENT consultant, Derby & Burton Hospitals
Dr Habib Zaidi
