DHS S&T Launch Online SARS-CoV-2 Airborne Decay Calulator

The Department of Homeland Security Science and Technology Directorate (S&T) added an online calculator last week that estimates the natural decay of SARS-CoV-2 in the air.

The calculator is based on research still underway at S&T’s National Biodefense Analysis and Countermeasures Center in Maryland.

“This groundbreaking research into how COVID-19 spreads and the new interactive model from DHS S&T will have far-reaching impact,” William Bryan, DHS Senior Official performing the duties of the Under Secretary for Science & Technology. “The easily accessible tool allows officials, the medical community, and individuals to make more informed decisions to protect their own health and well-being.”

Dubbed the airborne predictive model, the tool builds on a previous S&T tool that modeled the survival of SARS-CoV-2 on non-porous surfaces indoors. The predictive model evaluates and factors in the impact of conditions such as temperature, ranging from 50 to 86 degrees Fahrenheit; humidity, ranging from 20 to 70 percent; and sunlight, charting the effects of an ultraviolet index up to 10.

This tool goes to show how much more we have learned about SARS-CoV-2 in the past couple of months, and it is a fascinting tool to play with, even if you aren't scienfitically minded.
