Vitamin D deficiency tied to increased COVID-19 risk, unique UF data study finds

UF Health  online


Patients with a vitamin D deficiency were four times more likely to be COVID-19 positive than those with a sufficient amount of the crucial vitamin, a University of Florida research team has found. And African American patients with insufficient vitamin D levels were three times more likely to be infected by the coronavirus. Insufficient vitamin D has been linked with respiratory infections, and research suggests vitamin D treatment may help lessen symptoms of COVID-19.

Can Covid Lead to Impotence?

A connection has been reported in hundreds of papers by scientists in Europe and North America, as well as in Egypt, Turkey, Iran and Thailand.

Dental diseases are associated with increased odds ratio for coronavirus disease 19

Oral Diseases

Joseph Katz, et al.


Coronavirus disease 19 (COVID-19) risk factors are age, race, gender, and pre-existing conditions including cardiovascular, respiratory, and endocrine diseases. The severe acute respiratory corona virus 2 (SARS-CoV-2) binds to the angiotensin-converting enzyme 2 (ACE2) receptor for cellular entry and infects respiratory tract cells. Multiple organs, including kidneys, lungs, brain, and pharynxes, are affected and account for increased morbidity.
