Final answer:
The hands, specifically the thumbs, wrists, areas between the fingers, and under the fingernails, require extra attention during handwashing. Adequate lathering and proper technique according to CDC recommendations ensure the effective removal of pathogens. Handwashing for at least 20 seconds with soap and warm water is essential for preventing the spread of infections.
Step-by-step explanation:
The area of the body that requires extra attention during handwashing is the hands, particularly the thumbs, wrists, areas between the fingers, and under the fingernails. When washing your hands, it is important to apply soap and lather your hands thoroughly, including these areas, to effectively remove microorganisms. While the face, arms, legs, and feet are not the main focus of regular handwashing, the CDC handwashing recommendations emphasize the importance of proper technique and duration, suggesting at least 20 seconds of washing with soap and warm water.
To ensure handwashing is done correctly, start by wetting your hands with warm water, apply soap, and then rub your hands together to create a lather. Pay special attention to the backs of your hands, between your fingers, and under your nails. After lathering, rinse thoroughly with water flowing from the wrist to the fingertips, and dry your hands with a clean towel or hot air blower. Ideally, you should use a nail brush to remove any debris or microorganisms that might be under the fingernails.
Overall, handwashing is a crucial practice that can prevent the spread of infections and protect public health. Remember to wash your hands often, especially after activities that can expose you to pathogens like using the toilet, preparing food, or touching surfaces in public areas.
