'''Zinc''' is one of the oldest metals known to mankind,<ref>[Zinc, Wide Usage of a Modest Metal: One of the Earliest Metals to have Appeared in Human History]</ref> and a [[vitamin]] that is reportedly helpful to build immunity and protect against [[COVID-19]]. It is a [[element|chemical element]] with the symbol Zn and atomic number 30. In some historical and sculptural contexts, it is (or was) known as spelter. It is a [[transition metal]].

As reported in a study published in September 2020, "Zinc is a trace element with potent immunoregulatory, antiviral properties and is utilized in the treatment of COVID-19. ... Amongst COVID-19 positive patients, 27 (57.4%) were found Zinc deficient. These patients were found to have higher complications (P = 0.009), ARDS (18.5% vs 0%, P = 0.06), received corticosteroid therapy (P = 0.02), prolonged hospital stay (P = 0.05) and increased mortality (18.5% vs 0%, P = 0.06). The Odds ratio (OR) of developing complications in Zinc deficient COVID-19 patients was 5.54. More patients in the Zinc deficient group ... required ICU care (7 vs 2, P=0.266) and recorded deaths (5 (18.5%) vs 0 (0%), P=0.06) in comparison to patients with normal Zinc levels."<ref>https://www.sciencedirect.com/science/article/pii/S120197122030730X</ref>
Zinc is most commonly used to [[galvanization|galvanize]] other metals or alloys to make them [[corrosion]] resistant. It is also a main constituent of many coins. Zinc is a constituent of the alloy, [[Brass (metal)|Brass]].
