WhiteKnight : Mmmmmm, see your point but Africa, vast, hot, not showing the rates expected even though Social Distancing in Soweto must be the larf of the day. Interesting view here is possibly the hackneyed phrase "Underlying health issues". Middle East is also vast & hot but. oh dear, lots of enderlying issues I venture to suggest. I only did 17 years in Bahrain & I suggest that very poor diet choices and widespread obesity combined with the consequential Type 2 Diabetes would have had an impact on the "many cases" you suggest.
