The key role of zinc in elderly immunity: A possible approach in the COVID-19 crisis

Abstract

Background & aims: The COVID-19 infection can lead to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), mainly affecting patients aged 60 and older. Preliminary data suggest that the nutritional status can change the course of the infection, and on the matter, zinc is crucial for growth, development, and the maintenance of immune function. In the absence of treatment for this virus, there is an urgent need to find alternative methods that can contribute to control of disease. The aim of this paper is to establish the relation between zinc and COVID-19.

Methods and results: From the prior scientific knowledge, we have performed a review of the literature and examine the role of zinc in immune function in the infection by COVID-19. Our findings are that the zinc as an anti-inflammatory agent may help to optimize immune function and reduce the risk of infection.

Conclusions: Zinc supplementation can be a useful strategy to reduce the global burden of infection in the elderly, there is a need the increased reporting to improve our understanding of COVID-19 and the care of affected patients.

Keywords: Covid-19; Immunity; Zinc.
