What is the correct procedure for handwashing?

The procedure for handwashing that involves wetting the hands, applying soap, scrubbing for at least 20 seconds, rinsing, and drying hands is the correct approach because it effectively removes dirt, germs, and other contaminants. Each step has a specific purpose:

• Wetting the hands allows for the soap to spread and work effectively.

• Applying soap is essential as it binds to the dirt and microbes on the skin.

• Scrubbing for a minimum of 20 seconds is crucial, as this duration has been shown to significantly reduce the presence of harmful pathogens. The scrubbing action helps dislodge any particles or bacteria.

• Rinsing thoroughly removes the soap along with the lifted dirt and germs from the surface of the skin.

• Finally, drying the hands is important since germs can transfer more easily to and from wet surfaces.

This comprehensive process ensures optimal hygiene and is recommended by health organizations worldwide to prevent the spread of illness. Other methods described in the options do not incorporate these essential steps or lack the necessary duration and effectiveness required for proper handwashing.
