COVID-19 pandemic: Can zinc supplementation provide an additional shield against the infection?

Tldr; it might help to take zinc.

Out of 249 studied patients, there was 8% (21 patients) mortality. The investigators found a significantly lower plasma level of zinc in COVID-19 patients who died (43 μg/dl) than the patients who survived (63.1 μg/dl). After adjusting different variables, the investigators showed each unit increase of plasma zinc at the time of hospital admission resulted in a 7% reduced risk of in-hospital mortality.
