The pathogens that cause HAIs travel easily from person to person, person to surface and surface to person. This video by the Queen Elizabeth Hospital Birmingham shows how easily, quickly and broadly pathogens travel. C.difficile, norovirus and influenza cells spread like passengers on a commuter train. A few get off at every stop … and stay. A disinfection method that works uniformly, is unbiased and easy to use, like Nocospray can help stop pathogens from boarding the next train.
