Which method is most effective for preventing infection?

Washing hands frequently is the most effective method for preventing infection because it directly removes pathogens from the skin's surface. Proper hand hygiene, which involves using soap and water to clean hands thoroughly, is critical in healthcare settings to reduce the transmission of infections. It is especially important before and after patient contact, after using the restroom, and before eating or handling food. Handwashing not only removes dirt but also helps eliminate viruses and bacteria that may not be effectively killed by hand sanitizers.

While hand sanitizer can be useful in certain situations, it may not be as effective as washing with soap and water, especially when hands are visibly dirty or when dealing with certain types of pathogens, such as norovirus. Wearing gloves protects the skin from direct contact with bodily fluids, but it is essential to remember that gloves should not replace hand hygiene practices. Relying on standard precautions is important, as it encompasses various practices to reduce the risk of infection, but proper handwashing remains the cornerstone of infection prevention.
