Vitamina D y su importancia en la infección por SARS-CoV-2 Translated title: Vitamin D and its importance for infection with SARS-CoV-2

It’s since December 2019 that Corona virus disease (COVID-19) has emerged to be the global issue of concern. A “pandemic”; this is what WHO has declared about the COVID-19 outbreak on March 3rd, 2020. Vitamin D and its deficiency have recently been claimed to be one of the potential factors affecting COVID-19 risks and outcomes [1]. As Selberstein et al., has recently discussed the effect of vitamin D deficiency, and the role of vitamin D supplementation in COVID-19 patients [2], I’d believe that vitamin D binding protein (DBP) is maybe also involved. A closer look on DBP and its action on regulating the circulatory vitamin D levels, its polymorphisms and their impact on COVID-19 prevalence and mortality, will be briefly discussed.
