I don't know much about southern hemisphere's current SARS-CoV2 cases, but people everywhere are Vitamin-D deficient. Some recent research found that the old vitamin D recommendations were a fraction of what people actually need for optimal health [0]. Cities are particularly good at creating deficient populations. Human skin normally synthesizes vitamin D when exposed to ultraviolet light. People with darker skin need more sunlight to produce adequate vitamin D, which is presumably one of the main reasons why the super-virus' victims disproportionately have darker skin [1].
