What procedure is considered most effective in reducing the spread of infections?

Hand washing is regarded as one of the most effective procedures for reducing the spread of infections because it directly removes pathogens from the skin. Thorough hand washing with soap and water disrupts the oils and dirt on the hands that can harbor germs, allowing them to be washed away. This action significantly lowers the number of microorganisms that can be transmitted to patients, healthcare workers, and surfaces in medical settings.

While using disposable supplies, routine sterilization of equipment, and wearing face masks are all crucial infection control measures, they do not address the transmission of infections at the same fundamental level as hand hygiene. For instance, disposable supplies help prevent cross-contamination during procedures, but they do not eliminate pathogens from hands before contact with patients. Similarly, routine sterilization is effective for instruments but depends on them being cleaned appropriately beforehand. Wearing face masks helps reduce respiratory droplet transmission, but hand hygiene remains critical since many infections are spread through direct contact. Therefore, regular hand washing is a cornerstone of infection prevention strategies.
