How long is the recommended handwashing duration with soap and water, or the alternative use of alcohol-based hand rub?

• A. At least 20 seconds with soap and water, or using an alcohol-based rub.
• B. 5 seconds with sterile water only.
• C. 60 seconds with antibiotic soap.
• D. 1 minute while wearing gloves.

Answer: (A)

Hand hygiene effectiveness relies on giving the cleansing agent enough time to work. The recommended duration is at least 20 seconds when washing with soap and water, and if hands aren’t visibly dirty, an alcohol-based hand rub can be used, rubbing until the hands are dry. Soap and water physically remove dirt and microbes through mechanical action, while alcohol-based rubs inactivate a wide range of pathogens quickly when used properly.

This is the best choice because it matches standard guidance on how long to perform hand hygiene to ensure microbes are effectively reduced. A very short duration, like five seconds, won’t adequately remove contaminants. Extending the time to 60 seconds with antibiotic soap isn’t necessary or shown to provide extra benefit, and antibiotic soaps aren’t required for routine hand hygiene. Finally, doing a long hand-hygiene session while wearing gloves isn’t needed and gloves don’t replace proper hand hygiene; hand hygiene should be performed with or without gloves and gloves should be changed appropriately.
