Final answer:
The removal of germs during hand washing is achieved through rigorous scrubbing with soap and warm water, ensuring comprehensive coverage of all hand areas, and thorough rinsing and drying. This process, known as degerming, is crucial for public health.
Step-by-step explanation:
The part of hand washing that gets rid of germs involves several critical steps that work together to remove and kill pathogens.
- Using soap and warm water to scrub and create lather for at least 20 seconds.
- Ensuring you cover all parts of the hands including between the fingers, under nails, and up to the wrists.
- Rinsing thoroughly with water flowing from the wrist to the fingertips.
- Drying hands with a clean towel or using a hot air blower.
Hand washing is an example of degerming, which significantly reduces microbial numbers on the skin by scrubbing with soap, a mild chemical that removes pathogens without harshness. This process is essential for public health and preventing the spread of diseases, particularly after activities like coughing, sneezing, or interacting with contaminated surfaces.
