Question: 1 / 400

How long should hands be washed with soap and water according to the CDC guidelines?

5 Seconds

10 Seconds

15 Seconds

20 Seconds

The Centers for Disease Control and Prevention (CDC) guidelines recommend that hands should be washed with soap and water for at least 20 seconds. This duration is important because it allows enough time to effectively remove germs, dirt, and potential contaminants from the hands. Rubbing hands together during this time helps to create friction, which is crucial for dislodging particles and reducing the microbial load on skin surfaces.

While options suggesting shorter durations may seem pragmatic for quick hand hygiene, they do not provide the thorough cleansing necessary to minimize the risk of infection, especially in healthcare settings where hand hygiene is critical to patient safety. Adhering to the 20-second guideline is especially emphasized in high-risk environments like dialysis facilities, reinforcing the commitment to preventing the spread of infections through proper handwashing techniques.
