Which step follows after wetting hands and applying liquid soap in hand hygiene?

The step that follows wetting hands and applying liquid soap in hand hygiene is vigorously rubbing the hands together for 15-30 seconds. This action is crucial because it helps to create friction, which dislodges dirt, bacteria, and viruses from the skin's surface. The length of time specified (15-30 seconds) is important to ensure that the soap has sufficient contact with all areas of the hands, including between fingers and under the nails, for effective cleaning.

This vigorous rubbing action is foundational in hand hygiene practices, as it maximizes the effectiveness of the soap and minimizes the risk of transmission of infectious agents. Following this step, hands would then be rinsed thoroughly to remove dirt, soap, and any pathogens that have been loosened during the rubbing process.
