A team of experts from the University of Chicago Medicine has come up with a potential link between Vitamin D deficiency and COVID19 infection. Experts have said that people who have untreated Vitamin D deficiency are twice as likely to be diagnosed with COVID19 infection as compared to those, who have normal levels of Vitamin D. Scientists have observed around 489 COVID19 positive patients and got their Vitamin D levels checked within the year. They have found that people with this deficiency have developed a more severe COVID19 infection. Experts have claimed that such people might be at higher risk of death due to the disease. However, there is no evidence available to prove that Vitamin D can prevent COVID19 infection.
This study has been published in the journal of JAMA Network Open. As per the study, half of the Americans have Vitamin D deficiency. Black and Latin X Americans are at a higher rate of Vitamin D deficit. People living in areas Like Chicago, where sunlight is limited also deal with a lack of Vitamin D. Medical science says that Vitamin D is essential for the functioning of the immune system and it reduces the risk of respiratory tract infections. The lead author of the study has told that as per the statistics, it might help in reducing the risk of COVID19 as well. Nevertheless, experts around the world still need to analyze the potential of Vitamin D in declining the risk of coronavirus infection.
As per the scientists, shelter-in-place order to minimize the COVID19 infection might lead to decreased sun exposure. That might increase the requirement of Vitamin D supplements, which should not go beyond 4000 IU per day. However, the author of the research has said that Vitamin D supplements are inexpensive, and usually very safe, which can be widely scaled. Experts have emphasized the need for more substantial studies, which will determine what approach for Vitamin D supplementation will be suitable in specific populations. Scientists have started many clinical trials to come up with a more extensive plan for Vitamin D supplementation.
