What is the link between vitamin D levels and COVID-19?

A recent study has shown a correlation between vitamin D deficiency and COVID-19 severity and mortality.

It found that people with a vitamin D deficiency are more likely to develop a severe or critical case of COVID-19 compared to people who had sufficient levels of the vitamin in their blood.

Patients with a vitamin D deficiency were 14 times more likely to have a severe or critical case of COVID-19.

The mortality rate for those with insufficient vitamin D levels was 25.6%, compared with 2.3% among those with adequate levels.
