How should one properly wash hands to prevent infection?

Washing hands properly is crucial in preventing infection, and using soap and water while scrubbing for at least 20 seconds is the most effective method. The reason for the emphasis on soap is that it not only helps to physically remove dirt and pathogens from the skin but also interacts with them on a chemical level, breaking them down. The scrubbing action for a minimum of 20 seconds ensures that all surfaces of the hands, including between the fingers and under the nails, are thoroughly cleaned.

Effective handwashing involves several key elements: using clean, running water and applying enough soap to create a lather. By scrubbing for the appropriate duration, you significantly reduce the number of germs and pathogens present, which is vital in preventing the spread of infections, especially in a healthcare setting like home health care.

Other methods, such as rinsing only with water or relying solely on alcohol-based sanitizers, do not provide the same level of cleanliness. While alcohol-based sanitizers can be effective in certain situations, they are not a substitute for handwashing when hands are visibly soiled or greasy.
