Physicians at the Complete Med Care clinic in Dallas, Texas, have conducted a study showing that the prevalence of severe vitamin D deficiency is strongly correlated with coronavirus disease 2019 (COVID-19) mortality rate in European countries.
The researchers say the correlation also strengthened over time, making it even less likely to be a random effect.
Dr. Isaac Pugach and Dr. Sofya Pugach recommend that physicians perform universal screening for Vitamin D deficiency.
They also say vitamin D supplementation should be tested in randomized controlled trials as a potential new treatment or preventative approach to COVID-19.
