Coronavirus SarsCov2, formerly known as 2019-nCoV, is a positive-sense single-stranded RNA virus that is contagious in humans. As described by the US National Institutes of Health, it is the successor to SARS-CoV-1, the virus that caused the 2002–2004 SARS pandemic. Coronavirus SarsCov2 is a type of virus that can cause severe respiratory illness in humans. The virus works by infecting the cells of the respiratory tract, causing them to produce excess fluid and making it difficult to breathe.

There is no specific cure or prevention for Coronavirus infection, however, there are some general measures that can help reduce the risk of infection. These include washing hands regularly and thoroughly with soap and water, avoiding close contact with people who are sick, and avoiding touching eyes, nose, and mouth with unwashed hands. Additionally, good nutrition is important for supporting overall health and immunity.

There are several nutrients that are especially important for supporting immunity. These include vitamins A, C, and E, as well as zinc and selenium. Vitamin A helps to protect against infections by supporting the production of white blood cells. Vitamin C is an antioxidant that helps to protect cells from damage and supports the function of the immune system. Vitamin E also has antioxidant properties and helps to protect cell membranes from damage. Zinc is essential for the development and function of immune cells. Selenium is another nutrient that supports immune function.

Good sources of these nutrients include fruits, vegetables, whole grains, nuts, seeds, and legumes. For example, vitamin A is found in orange and yellow fruits and vegetables such as carrots and sweet potatoes; vitamin C is found in citrus fruits such as oranges and grapefruit; vitamin E is found in nuts and seeds; zinc is found in whole grains and legumes; and selenium is found in Brazil nuts.  Including these nutrient-rich foods in the diet can help to support overall health and immunity. Additionally, there are some supplements that contain these nutrients that can be taken if dietary intake is insufficient.
