Tools and Calculators

Health Systems & Hospitals

COVID-19 Acute and Intense Resource Tool (CAIC-RT)
"interactive online tool capable of estimating the maximum daily number of incident COVID- 19 cases that a healthcare system could manage given age-based case distribution and severity"

Infectious Agent

Estimated Surface Decay of SARS-CoV-2 (Department of Homeland Security)
"Select surface type, enter temperature, and enter relative humidity. The resulting decay of SARS-CoV-2 is shown in the table below."
Estimated Airborne Decay of SARS-CoV-2 (virus that causes COVID-19)
Department of Homeland Security
"select the UV index, temperature and relative humidity of interest. Information on how long SARS-CoV-2 would be expected to remain stable in aerosols (airborne) will be displayed in the table below. "

Transmission

COVID-19 Airborne Transmission Tool Available (CIRES)
Spreadsheet-based tool "calculates COVID-19 infection risk for a number of basic situations: college classrooms, choirs, taking a bus, being outdoors, participating in demonstrations. The model is downloadable and free, and users can tweak inputs to ask, for example, what’s my risk if other students wear or don’t wear masks? And can my choir sing together more safely by moving outdoors?"
