After studying global data from the novel coronavirus (COVID-19) pandemic,
researchers have discovered a strong correlation between severe vitamin D deficiency and mortality rates.Led by Northwestern University, the research team conducted a statistical analysis of data from hospitals and clinics across China, France, Germany, Italy, Iran, South Korea, Spain, Switzerland, the United Kingdom (UK) and the United States.
The researchers noted that patients from countries with high COVID-19 mortality rates, such as Italy, Spain and the UK, had lower levels of vitamin D compared to patients in countries that were not as severely affected.
This does not mean that everyone — especially those without a known deficiency — needs to start hoarding supplements, the researchers caution.
"While I think it is important for people to know that vitamin D deficiency might play a role in mortality, we don't need to push vitamin D on everybody," said Northwestern's
Vadim Backman, who led the research. "This needs further study, and I hope our work will stimulate interest in this area. The data also may illuminate the mechanism of mortality, which, if proven, could lead to new therapeutic targets."
The
research is available on medRxiv, a preprint server for health sciences.
Comment: This is just the latest report to confirm suspicions that the coronavirus has been circulating for a lot longer than presumed; reports from France state that its athletes encountered it in October 2019 at the international Military Games in Wuhan; Italy and Sweden stating that they likely encountered coronavirus in November 2019, meanwhile Ireland suspects cases began in December 2019.
