The Influence of Temperature and UV Light on SARS-Cov-2

UV light

A study in Lancet looked at viability of the virus at 4 degrees celsius (which is the refrigerator temperature), at room temperature and at human body temperature.

In liquid SARS-Cov 2 is stable at 4 degrees Celsius , that is in the refrigerator for over a week.   Therefore any item that is contaminated with the virus will continue to carry the virus for up to one week.   Be sure to keep fruits out for a day or two before putting them in the refrigerator if you think it may have been touched. Alternatively you could wash fruits such as oranges and bananas with soap water to clean them and then place in refrigerator.

Anything that can be placed in a warm place should be because at room temperature it takes 3 days for the viral load to go down 10 fold.   

At 150 degrees Fahrenheit the virus dies in a minute. Therefore normal cooking on the stove or the oven kills it.

It is also sensitive to UV , 90% of the virus is eliminated by 3 hours of direct sunlight.

The SARS virus is 2-3 times more sensitive that influenza virus to ultraviolet.
