Abstract

Efficient and automated methods of disinfecting surfaces contaminated with the Middle Eastern respiratory syndrome coronavirus (MERS-CoV) may prevent the spread of the virus. Here we report the efficacy and use of an automated triple-emitter whole room UV-C disinfection system to inactivate mouse hepatitis virus, strain A59 (MHV-A59) and MERS-CoV viruses on surfaces with a >5 log10 reduction.

Log reduction of MHV-A59 following Surfacide UV-C exposure at a 4-foot distance (1.22 m). Virus was reduced by 2.71 log10 in 5 minutes and by 6.11 log10 in 10 minutes to undetectable levels. Results are the means of triplicate samples.
