NEW DELHI: There is no clinical evidence to prove low levels of Vitamin D lead to severe COVID-19 symptoms but there is a definite connect between the тАЬsunshine vitaminтАЭ and immune responses to the disease, say experts as the pandemic spreads across the world and concerns mount over a new mutant strain. Stressing that Vitamin D is inexpensive and has negligible risk when compared to the considerable risk of COVID-19, global researchers on the disease have asked governments to make it part of their strategy against the novel coronavirus. Many factors such as age, being male and comorbidities are known to predispose individuals to higher risk from exposure to SARS-CoV-2, but inadequate Vitamin D is by far the most easily and quickly modifiable risk factor with abundant evidence to support a large beneficial effect, said Prof Afrozul Haq, former dean┬аof the School of Interdisciplinary Sciences and Technology (SIST) at New DelhiтАЩs Jamia Hamdard University.
