Summary
Some vitamins play a beneficial role in the immune system and certain diseases may be associated with an increase in the number of COVID-19 cases and mortality. In this work, we found that countries with the highest number of cases and deaths by COVID-19 are the countries with the highest death rates from different types of cancer and multiple sclerosis. Besides, the relationship between cancer death rate and COVID-19 is not biased by the Life expectancy. We also found that vitamin A sufficiency can be related to the number of recovered from COVID-19 worldwide and the low solar incidence can be related to the number of cases and deaths by COVID-19. Our findings suggest a direct relationship between cancer, multiple sclerosis, and COVID-19. We also suggest that Vitamins D and A may play a protective role in COVID-19.
