Which of the following is a key component of proper handwashing?

Using soap and water for at least 20 seconds is a critical component of proper handwashing because it effectively removes dirt, grease, and microbes from the skin. The process of scrubbing hands for this duration ensures that even the most stubborn bacteria and viruses are dislodged and washed away. Studies have demonstrated that washing for a minimum of 20 seconds significantly reduces the presence of pathogens, thus lowering the risk of foodborne illnesses.

Utilizing soap aids in the breakdown of oils and contaminants on the skin, creating a lather that traps and carries away germs during rinsing. This thorough approach contrasts with shorter washing durations or the absence of soap, which might not be sufficient to achieve effective hand hygiene.

The temperature of the water also plays a role, but what’s most crucial is that hands are washed thoroughly with soap and for the right duration. Therefore, a minimum of 20 seconds with soap is the standard recommended by health authorities worldwide for effective hand hygiene.
