Hand washing is recognized as the most important procedure in preventing disease transmission in healthcare settings due to its effectiveness in physically removing pathogens from the skin. This practice reduces the likelihood of transferring infectious agents between patients, healthcare workers, and the environment.

While using hand sanitizer, wearing masks, and cleaning surfaces are all vital components of infection control, they often serve as supplementary measures to hand washing. Hand sanitizers are effective when soap and water are not available but may not eliminate all types of germs, especially if hands are visibly soiled. Masks are crucial for protecting against respiratory droplet transmission, particularly in cases of airborne illnesses, but they do not address contact transmission. Similarly, cleaning surfaces is important to reduce contamination but does not directly impact the cleanliness of hands, which is where many infections are initiated. Thus, hand washing stands out as the foundational practice for maintaining hygiene and preventing infection in clinical environments.
