Reduce pathogen transmission associated with washing and drying hands.
This WELL feature requires sufficiently large sinks, disposable soap containers and hand drying towels.
Washing hands with soap is a recommended and effective way of removing dirt and bacteria and can greatly reduce transmission and incidence of gastrointestinal disease, including diarrhea, and respiratory disease. However, the hands will only become as clean as the surrounding environment. Sinks, which often have standing water and relatively infrequent cleaning, can house pathogenic bacteria that can migrate onto hands if touched. Liquid soap dispensers are another place that frequently become homes for bacteria; even when cleaned, the soap and inside of the container often remain contaminated, indicating that the dispensers should not be topped off or refilled. Once an individual's hands are cleaned, they can more easily become re-infected when wet compared to when dry.
Sinks and faucets should be designed in such a way as to avoid unnecessary contact with the hands. Bathrooms should include paper towels for hand drying, as there is stronger evidence about the ability of paper towels to dry hands and remove bacteria, as compared to air dryers.
