Vitamin D: Some studies have suggested that vitamin D may aid to protect against becoming infected with COVID-19 as well as providing protection from developing serious symptoms of the illness. Some studies have shown that people with low vitamin D levels may be more susceptible to upper respiratory tract infections. Moreover, individuals who took vitamin D supplements, particularly those who had low vitamin D levels, were less likely to develop acute respiratory tract infections than those who did not take supplements. It is postulated that vitamin D may protect against COVID-19 in two ways. First, it may help boost the bodies' natural defense against viruses and bacteria and secondly, it may help prevent an exaggerated inflammatory response, which has been shown to contribute to severe illness in some people with COVID-19. Currently, the latest NIH guidelines for COVID-19 treatment indicate that there is insufficient evidence to recommend for or against the use of vitamin D for the prevention or treatment of COVID-19.
Summary: At this time, prevention of COVID-19 can effectively be done by becoming vaccinated. (Vaccines will be described in next the section). In addition, using a combination of techniques including physical/social distancing, hand washing/disinfection, and using face masks can assist in preventing the illness.
Treatment for patients with COVID-19 depends on the severity of the illness and the patient’s symptoms. Currently, care for patients is primarily supportive to help relieve symptoms and manage respiratory and other organ failures. Most patients with COVID-19 can recover at home with adequate rest, staying hydrated, and taking medications to relieve fever, aches and pains. Hospitalization may be required for COVID-19 patients who are critically ill and have more severe symptoms. In addition, certain treatments have been approved by the NIH including the use of Remdesivir, Dexamethasone, and Monoclonal Antibodies.
