description The acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic has affected millions of individuals, causing major health and economic disruptions worldwide. The pandemic is still raging, with a second and third wave in a few countries, while new infections steadily rise in India. Nutrition and immune status are two critical aspects of fighting the virus successfully. Recently, selenium status was reported to positively correlate with the survival of patients with COVID-19 compared with non-survivors. We analyzed the blood serum levels in 30 apparently healthy individuals and in 30 patients with confirmed COVID-19 infection in the southern part of India. The patients showed significantly lower selenium levels of 69.2 ± 8.7 ng/mL than controls 79.1 ± 10.9 ng/mL. The difference was statistically significant (P = 0.0003). Interestingly, the control group showed a borderline level of selenium, suggesting that the level of this micronutrient is not optimum in the population studied. The results of this exploratory study pave the way for further research in a larger population and suggest that selenium supplementation may be helpful in reducing the effects of the virus. •The acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic is a major health concern.•Nutrition and immune status are two critical aspects of fighting the virus successfully.•Patients with COVID-19 from southern India showed a significantly lower selenium level in serum compared with controls.•Controls had borderline levels of selenium, suggesting that the level of this micronutrient is not optimum in the population studied.•Selenium supplementation may be helpful in reducing the effects of the virus.
