BBC: Vitamin D: The truth about an alleged Covid ‘cover-up’. “There are many treatments that have been suggested for Covid-19. Hydroxychloroquine, Ivermectin and vitamin D – all are, or were, being studied. Suggesting that a treatment could be effective and then finding it isn’t upon further research is all part of the normal scientific process. But online, early or low quality research can be shared out of context. And the confusion this creates can be exploited by people promoting conspiracy theories.”
JAMA Network: Association of Vitamin D Levels, Race/Ethnicity, and Clinical Characteristics With COVID-19 Test Results
JAMA Network: Association of Vitamin D Levels, Race/Ethnicity, and Clinical Characteristics With COVID-19 Test Results. “In this cohort study of 4638 individuals with a measured vitamin D level in the year before undergoing COVID-19 testing, the risk of having positive results in Black individuals was 2.64-fold greater with a vitamin D level of 30 to 39.9 ng/mL than a level of 40 ng/mL or greater and decreased by 5% per 1-ng/mL increase in level among individuals with a level of 30 ng/mL or greater. There were no statistically significant associations of vitamin D levels with COVID-19 positivity rates in White individuals.”
WCVB: Vitamin D eyed as possible new tool in fight against coronavirus. “Brigham and Women’s Hospital will look at whether vitamin D can lessen the severity of COVID-19 symptoms. Researchers are also studying whether vitamin D supplements reduce the chance of becoming infected if you have been exposed to someone in your household who tested positive for COVID-19.”
UChicago Medicine: Vitamin D deficiency may raise risk of getting COVID-19. “The research team looked at 489 UChicago Medicine patients whose vitamin D level was measured within a year before being tested for COVID-19. Patients who had vitamin D deficiency (< 20ng/ml) that was not treated were almost twice as likely to test positive for the COVID-19 coronavirus compared to patients who had sufficient levels of the vitamin."
AccuWeather: Severity of COVID-19 may depend on where you’re located on the map, new study suggests. “Vitamin D plays a critical role in preventing respiratory infections and boosting the immune system, and a study published by scientists in Ireland analyzed the correlation between vitamin D deficiency and the different mortality rates countries have seen in recent months. Dr. Eamon Laird and Professor Rose Anne Kenny from Trinity College Dublin in Ireland drew a link between vitamin D and the severity of coronavirus impacts in Ireland, including mortality rate, in a recently published study that focused on the implications of vitamin D deficiency on the severity of COVID-19.”
