Improved estimates of 222 nm far-UVC susceptibility for aerosolized human coronavirus via a validated high-fidelity coupled radiation-CFD code

Summary

A computer model, checked against lab data, estimates how quickly airborne coronavirus is inactivated by 222 nm light in a room. It is a modelling study, not a test in people.

Key points

• Combines light-spread and airflow modelling.
• Gives updated estimates of how sensitive airborne coronavirus is to 222 nm light.
• A model; results depend on its assumptions.
