Clinical and subclinical micronutrient deficiencies common in older adults are known to contribute to decreased immune function and age-related diseases [11] , implying that nutritional management is essential to reduce the risk of severe infection [12] . In view of a lack of clinical data on preventive and/or therapeutic efficiency of the nutritive adequacy of selenium, zinc, and vitamin D in COVID-19, we, in the present narrative review, discussed recent clinical data on the role of these micronutrients in the protection against bronchopulmonary infections, as well as the existing indications of their impact on COVID-19. We did a literature search for the period 2010-2020 on PubMed, Medline, and Google Scholar with the keywords of SARS, SARS-CoV-2, COVID 19, coronavirus, micronutrients (zinc, selenium, vitamin D), immune system, inflammation, prevention, and treatment.	./cache/cord-311965-3x3tjzhi.txt	./txt/cord-311965-3x3tjzhi.txt
