What is the minimum time recommended for handwashing?

• A. 5 seconds
• B. 7 seconds
• C. 10 seconds
• D. 15 seconds

Answer: (B)

Seven seconds is the minimum time recommended because it gives enough rubbing and lathering to lift and rinse away most germs when soap is used and hands are scrubbed all over. Five seconds is too short for thorough cleaning, while longer times like ten or fifteen seconds provide more cleaning but aren’t the minimum requirement in this context. The idea is to balance practicality with effectiveness, ensuring you cover all hand surfaces and then rinse well, followed by drying to reduce moisture where germs can spread.
