What is the minimum recommended handwashing duration?

• A. 5 seconds
• B. 2 minutes
• C. 1 second
• D. At least 20 seconds with soap

Answer: (D)

The key idea is how long you scrub with soap to wash away germs. You should wash for at least 20 seconds with soap and clean running water. This duration provides enough friction for the soap to lift dirt and microbes from all parts of your hands—front and back, between fingers, under nails, and around the wrists—so they can be rinsed away. Shorter times, like a few seconds, often leave germs behind, while 2 minutes is longer than necessary for most situations. After scrubbing for about 20 seconds, rinse well and dry to complete the process. To time it, you can hum a short song or count to 20.
