Researchers planted tracer viruses (which resemble the human norovirus) to contaminate one or two commonly touched surfaces — a doorknob or table top — at the beginning of the day in office buildings, a conference room, and a healthcare facility. After various periods of time (from 2 to 8 hours), they sampled 60 to 100 surfaces, such as light switches, countertops, coffee pot handles, and phones, looking for the tracer virus.
The result: Within 2 to 4 hours, between 40 to 60% of the surfaces sampled were contaminated!
Fortunately, while that’s an intimidatingly fast spread time, there is a simple way to reduce threat of exposure: disinfectant. In the intervention phase, employees were provided with disinfectant wipes to use on their work areas at least once a day — at which point the number of contaminated surfaces was reduced by at least 80%
