Question: 1 / 400

The MINIMUM time needed for effective hand washing is?

10 seconds

15 seconds

20 seconds

The minimum time needed for effective hand washing is generally recognized to be 20 seconds. This duration is important because research has shown that washing hands for at least 20 seconds significantly reduces the number of pathogens present on the skin. Shorter durations, such as 10 or 15 seconds, may not adequately remove all harmful microorganisms, which can lead to the persistence of bacteria and viruses that cause infections. The Centers for Disease Control and Prevention (CDC) recommends washing hands thoroughly with soap and water for at least 20 seconds to ensure thorough cleansing, which includes scrubbing all surfaces of the hands—between fingers, under nails, and around wrists. Therefore, the selection of 20 seconds aligns with established public health guidelines for hand hygiene in various settings, including healthcare and sterile processing environments.
