New data and research results showing that it is possible that vitamin D deficiency causes the severity of new coronaviruses to vary from country to country
A new finding was presented regarding the relationship between vitamin D and COVID-19, although the results of studies have shown that vitamin C is deficient in severe coronavirus (COVID-19) patients.

Vitamin D is a vitamin contained in fish such as salmon and tuna, cheese, and mushrooms. It is classified as an essential nutrient that cannot be biosynthesized by the human body, but it is also biosynthesized by exposure to sunlight.
Vitamin D has been shown in previous studies to regulate the response of white blood cells that prevents excessive release of cytokines. While it has been reported that the COVID-19 critically ill patients have a runaway immune system and cytokine storm , vitamin D deficiency was observed in many of the COVID-19 critically ill patients on April 30, 2020. Was announced. Although the infection status of COVID-19 varies from country to country, it is unknown at the time of writing the article what causes this difference, so the results of the survey received a great deal of attention.

Later, new research results investigating the relationship between COVID-19 and vitamin D were published on May 6 and 11.
Published on June 6 is a paper by a research team including Dr. Lee Smith of Anglia Ruskin University in the UK and Petre Christian Ily of the King Elizabeth Hospital Kingslyn NHS Trust Foundation. The research team investigated the relationship between average vitamin D levels and COVID-19 cases and mortality among nationals. As a result, 'in 20 European countries, there was a correlation between national vitamin D levels and COVID-19 cases, especially mortality,' said Dr Smith. Especially in Italy, Spain and Switzerland, the average vitamin D level of the elderly is low, which is consistent with the group with severe COVID-19.
Also on the 11th, Professor Rose Ann Kenny from Trinity College, Dr. Amen Laird, and John Rose from the University of Liverpool announced the relationship between vitamin D and COVID-19 mortality. This study also shows that low latitudes in Spain and northern Italy have low levels of vitamin D in the body and are prone to deficiency. On the other hand, in Norway, Finland, and Sweden, the amount of sunlight and ultraviolet rays is low, but vitamin D levels are high because supplements and dietary vitamin D are being supplemented. COVID-19 infection and lethality are low in the Nordic countries, and there is a 'statistically significant correlation' between vitamin D levels and COVID-19 lethality.
On the other hand, any research results peer review is not performed preprinted should be noted in that it is (refereed previous thesis). Since scientific papers are usually justified by being evaluated by multiple experts, caution is being exercised in leaving these papers alone.
A 2017 systematic review showed that taking vitamin D supplements may reduce the risk of respiratory infections, but the risk reduction rate was only 3%, which was the mother of the study. Differences were seen in the group. It is believed that it is premature to conclude that 'a vitamin D supplement can prevent the severity of COVID-19 from increasing.'
