摘要
With the advent of twenty-first century, we are in cruel grip of a pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the associated illness being called as COVID-19. Since its outbreak in December 2019 in Wuhan, China, there are no medicines to cure the disease till date. Based on their experience, scientists say that developing a coronavirus vaccine could take at least a year. There are many steps in place before the vaccine comes for the distribution like its safety and cost-effectiveness, especially for the developing countries. In this scenario, the only way to prevent the disease is by following certain safety guidelines and to boost up the body's immune system. Zinc, a crucial trace element involved in several biological and metabolic processes, has been found to play a pivotal role in promoting and appropriately regulating the host defense mechanisms against viral infections. Zinc is naturally present in some foods, fortified in others and also available as dietary supplement. The current RDA (Recommended Daily Allowance) of zinc is 12 and 10 mg for males and females respectively. Zinc is the second most common trace mineral after iron in the cell. It is present in all organs and tissues in the body as it forms catalytic component of all 6 classes of enzymes encompassing almost 2000 enzymes in the body. Zinc is biologically essential for cellular processes, including growth and development, as well as DNA synthesis and RNA transcription. Zinc deficiency results in a number of metabolic changes besides a compromised immune system. In this review, the role of zinc in regulating the host defense and viral replication is being discussed with the main focus on COVID-19.
