"The records of individuals admitted between April 7th, 2020 and February 4th2021 to the Galilee Medical Center (GMC) in Nahariya, Israel with positive polymerase chain reaction (PCR) tests for SARS-CoV were searched for vitamin D (VitD) levels measured 14 to 730 days prior to the positive PCR test.
Measurements:
Patients admitted to GMC with COVID19 were categorized according to disease severity and Vitamin D level.
Association between pre-infection VitD levels and COVID19 severity was ascertained utilizing a multivariate regression analysis.
Results:
... Compared with mildly or moderately diseased patients, those with severe or critical COVID-19 disease were more likely to have pre-infection vitamin D deficiency of less than 20 ng/mL, be older, and have diabetes.
Vitamin D deficiency was associated with higher rates of mortality and comorbidities including COPD (p=0.006), diabetes (p=0.026), and hypertension (p =0.016).
Conclusions:
Among hospitalized COVID-19 patients, pre-infection deficiency of vitamin D was associated with increased disease severity and mortality"
Our nation became a circus with Covid in 2020. The news media became the public relations firm of a government that decides what you don't need to know, and how to slant what you do need to know. Blog motto: "Is that true, or did you read it in the New York Times?" ... “Politics is the art of looking for trouble, finding it everywhere, diagnosing it incorrectly, and applying the wrong remedies.” ...
