As the twenty-first century has arrived an epidemic caused by the Middle East Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) and its associated disease, COVID-19, are currently underway. The illness first seen in (Wuhan) China, in December 2019, there have been no cures. The prior research shown that the scientists predict the developing a corona virus vaccine will require a minimum one year. Before the vaccine is given out, a number of precautions must be taken to guarantee both safety and affordability, particularly in developing countries. In this situation, taking specific safety precautions and boosting one's immune system are the only ways to prevent getting the disease. It has been found that Zn, an important trace component involved in many physiological and enzymatic activities, is crucial for triggering and effectively controlling the host's defence mechanisms against viral infections. In addition to being available as a dietary supplement, Zn can also be found naturally in some foods and is fortified in others. Men and women should consume 12 mg and 10 mg of Zn daily, respectively, according to the most recent RDA. Zn is the 2nd most prevalent trace mineral in the cell after iron. It is a constituent of all six classes of enzymes, which together make up roughly 2000 enzymes, and is distributed throughout the body's systems and tissues. Numerous physiological activities, including growth, DNA synthesis and RNA transcription, depend on Zn. Zn deficiency may give the results of compromised immune system and a number of metabolic problems. In this review, the importance of Zn in boosting and regulating host defence vs. virus reproduction is examined, in the prevalence of COVID-19.
