Abstract

Floors are an underappreciated fomite or source of pathogens. These pathogens can transfer to our hands, and from there, further spread to other surfaces including our mucosal surfaces, which can make us sick. Unfortunately, regular cleaning of floors (typically through mopping) is not sufficient, as the number of bacteria, fungi, and viruses can easily be replenished through the introduction of outdoor sources on shoes. Eliminating these pathogens at multiple entry and exit points can greatly reduce the spread from different areas, and are further enhanced by employing combination disinfection, which is the use of two complementary technologies to eliminate harmful microorganisms.
