Strengthening the immune system is one of the most important ways to fight this disease and vitamins such as vitamin A are from the elements for immune system enhancement. Due to the special role of vitamin A in the body, its deficiency may lead to increasing the burden of infectious diseases, especially in high-risk groups. Vitamin A has a therapeutic role in diseases of the respiratory system and its mucosal cells. The present review study aimed to investigate the effect of vitamin A on the treatment of infectious diseases especially the respiratory disease caused by COVID-19 and strengthen of the immune system. In this narrative review article, databases, Google scholar, PubMed and SID were searched and sources were extracted from 1998 to 2020. In the present study, 41 articles and books were reviewed. The results of study showed that vitamin A deficiency during the day seems to weaken the body against viral infections such as COVID-19 and has a negative effect on strengthening the immune system. Consuming as much vitamin A can be effective on the inhibition of viral infections and have effects on acute respiratory diseases treatment including the infection caused by viruses such as COVID-19 and can strengthen the immune system.
