According to the World Health Organization, the hand washing process should take approximately how long?

The correct duration for the hand washing process, as advocated by the World Health Organization (WHO), is approximately 40-60 seconds. This timeframe allows for thorough cleaning of all surfaces of the hands to effectively eliminate pathogens. Hand washing involves multiple steps, including applying soap, lathering for at least 20 seconds, and rinsing thoroughly, which all contribute to achieving effective hygiene. The need for this duration stems from ensuring that there is sufficient time for the antimicrobial action of soap and water to take place, thereby effectively reducing the risk of infections and the transmission of diseases. Shorter durations may not allow for adequate cleaning, while longer times may not be necessary and could lead to decreased compliance among individuals.
