What is the rationale for hand hygiene in preventive care?

• A. Improves skin condition
• B. It is a social norm
• C. Reduces spread of infections
• D. No effect on disease risk

Answer: (C)

Hand hygiene works by breaking the chain of infection. Our hands pick up many pathogens through everyday contact, and they can transfer bacteria and viruses to the mouth, nose, eyes, or to surfaces and other people. Cleaning hands with soap and water or using an alcohol-based sanitizer dramatically reduces the number of microbes on the hands, so the likelihood that these pathogens are passed along is much lower. In preventive care for children, this means washing or sanitizing before touching a child, before feeding, after diaper changes, after coughing or sneezing, and after handling equipment—all actions that prevent infections from spreading in clinics and home settings. While hand hygiene can improve skin feel or hygiene habits can be socially encouraged, its main purpose is to reduce disease risk by stopping transmission.
