What is the recommended duration for scrubbing hands and the song to sing?

• A. 20 seconds, Happy Birthday
• B. 10 seconds, Jingle Bells
• C. 15 seconds, ABC Song
• D. 30 seconds, Row Your Boat

Answer: (A)

The key idea is to scrub long enough to remove germs: about 20 seconds. Using a familiar tune helps pace you so you don’t rush or skip areas. Singing “Happy Birthday” provides a timer that lines up with roughly twenty seconds, guiding you to scrub all parts of the hands—palms, backs, between fingers, under nails, and thumbs—before rinsing. After rinsing, dry thoroughly to remove lingering germs.
