55; p=0.01; R =0.31) and mortalities (r=0.50; p=0.01; R =0.25). Moreover, the associations for the COVID-19 infections and mortalities improved to r=0.76 (p=0.002; R =0.58) and r=0.65 (p=0.03; R =0.42), respectively, after predicting with confounding factors. Similarly, mean vitamin D level had a significant negative correlation with COVID-19 infections (r=-0.77; p=0.04; R =0.59) and mortalities (r=-0.80; p=0.03; R =0.63) when combining with confounders. Prevalence of vitamin D deficiency is significantly positively associated whereas
