The universally acknowledged most important method of preventing communicable diseases is hand hygiene, specifically washing hands with soap and water or using alcohol-based hand sanitizers. This practice is considered the single most effective way to reduce the transmission of infectious agents in both healthcare settings and the general community, as it removes pathogens that can be spread by touching the eyes, nose, mouth, food, or other surfaces.
