Use the tools below to estimate surface decay and airborne decay of COVID-19.
Science and Technology (S&T) partnered with Countering Weapons of Mass Destruction (CWMD) to develop these tools, used by Occupational Safety and Health (OSH) professionals to support risk assessment, cleaning and disinfection.
Estimate Surface Decay
Use the sliders, or enter temperature and relative humidity in the provided fields. Information on how long COVID-19 would be expected to remain stable on surfaces will be shown in the COVID Stability section of the table.
Estimate Airborne Decay
Use the sliders, or enter the UV index, temperature and relative humidity in the provided fields. Information on how long COVID-19 would be expected to remain stable airborne will be displayed in the COVID Stability section of the table.
