Vitamin D’s Association with COVID-19 Prevention and Treatment

Abstract

The SARS-CoV-2 has been creating havoc worldwide for more than 3 years and is as problematic as ever. Up to this day, more than 275 million people have been infected and 2.2 million killed. With the well-established and high coverage of COVID-19 vaccines, severe symptoms are becoming less common, yet mild symptoms still trouble many. Therefore, a short-term cheap relief treatment that most civilians worldwide can use for such mild symptoms has to be implemented. Vitamin D has become a possible option as statistics and research have shown a strong correlation between vitamin D level and infection rate and severity of COVID-19. This paper will discuss the relationship between vitamin D and COVID-19 through 1) Function of vitamin D, 2) Population affected by vitamin D deficiency, 3) Vitamin D deficiency aggravating symptoms of COVID-19, 4) A statistical analysis of 4131 patients on their COVID-19 test results and vitamin D level, and finally 5) A discussion on vitamin D deficiency leading to an increase in COVID-19 infection and severity rate.
