What is the procedure for effective handwashing?

The procedure for effective handwashing is best described by the first choice: Wet hands, apply soap, scrub for at least 20 seconds, rinse, and dry with a clean towel. This method is rooted in guidelines recommended by health authorities to minimize the risk of spreading germs.

Starting with wet hands helps to activate the soap, which is crucial for breaking down dirt, grease, and pathogens. The application of soap is essential because it reduces the surface tension of water, allowing for better cleaning. Scrubbing for at least 20 seconds is a key component, as this duration is deemed sufficient to remove microorganisms effectively. The friction created while scrubbing physically dislodges dirt and bacteria from the skin. Rinsing under clean running water removes the loosened germs and soap residue. Finally, drying hands with a clean towel or air dryer is important because damp hands can easily attract and transfer germs. A clean towel also aids in removing any remaining bacteria.

Other responses do not adhere to the proper guidelines for effective hand hygiene. For example, simply scrubbing without soap is inadequate to eliminate harmful microbes, and using sanitizer without proper washing does not address dirt and grime effectively. Washing for a mere 5 seconds fails to provide sufficient time to properly cleanse hands,
