Abstract

The latitude dependence of death rates due to COVID-19 infection suggests a possible relationship to vitamin D deficiency. This relationship is made stronger when one compares the surprisingly low rates of vitamin D deficiency in Scandinavian countries to their correspondingly low rates of death among COVID-19 patients. At the same time, low-latitude nations that report the highest death rates due to COVID-19 (Indonesia and the Philippines) have also previously reported unexpectedly high rates of vitamin D deficiency. The analysis presented here, while of meager statistical rigor, suggests that public-health authorities around the world should quickly develop an inexpensive but rigorous experimental test of the following simple hypothesis: COVID-19 morbidity and mortality are correlated with vitamin D deficiency.
