Step-by-step explanation:
Handwashing is critical for public health and should be emphasized in a clinical setting. The CDC recommends handwashing before, during, and after various activities, including interacting with someone who is ill. This is because pathogens can be transmitted through direct contact with infected individuals or contaminated objects. Washing hands with soap and water or using hand sanitizer helps remove and kill bacteria and viruses, reducing the risk of infection.
