“Hands contaminated with pathogenic microbes play a major role in the transmission of bacteria in health care institutions, the food industry, and community and domestic settings”. Read this article by John Ross on Harvard Health publishing to see how hand dryers seriously contribute to spreading germs and cross-contamination.
