United States. The U.S. Department of Homeland Security has two modeling options available to the public that allow analyzing the degree of disintegration in an estimated airborne and the estimated degree of decay in the air of SARS-CoV-2 (virus that causes COVID-19), under a range of temperatures, relative humidity and UV index.
The virtual system allows you to use the sliders to select the UV index, temperature and relative humidity of interest. Information about how long SARS-CoV-2 is expected to remain stable in aerosols (in the air) or on surfaces will be shown in tables. Users can find the environmental conditions for a specific location by accessing general weather resources online.
Prediction ability is limited to a temperature between 74-95°F and a relative humidity between 20-60% for a UV index of 0, and a temperature of 68°F and a relative humidity of 20% for a UV index between 1.5 and 12.
