Which of the following is a critical step in infection control?

Washing hands is a critical step in infection control because it is one of the most effective ways to prevent the spread of infections in healthcare settings. Hands can easily carry pathogens from one surface or person to another, which can lead to healthcare-associated infections (HAIs). By washing hands thoroughly with soap and water or using hand sanitizer, healthcare workers can significantly reduce the number of germs they transfer to patients, other staff, and themselves.

This practice is rooted in the principles of hygiene and is supported by evidence showing that proper hand hygiene lowers the incidence of infections. It's essential in various situations, such as before and after patient contact, before procedures, and after handling contaminated materials. This consistent action helps maintain a sterile environment and protects both the patient and the healthcare provider.
