Why is hand hygiene critical in infection control?

• A. Reduces transmission of pathogens and prevents healthcare-associated infections
• B. Increases resistance to antibiotics
• C. Improves patient satisfaction scores only
• D. Is optional in most settings

Answer: (A)

Hand hygiene is a cornerstone of infection control because clean hands stop the spread of germs. By removing or killing pathogens on the hands, it prevents transferring them between patients, healthcare workers, and the surrounding environment, which lowers the incidence of healthcare-associated infections. In practice, this means washing or sanitizing at key moments—before touching a patient, before performing procedures, after exposure to body fluids, and after touching the patient’s surroundings—to break the transmission chain. This approach is standard in care settings and supported by established guidelines like the WHO’s hand hygiene moments. It does not increase antibiotic resistance; reducing infections can actually lessen antibiotic use, and it isn’t merely about patient satisfaction or optional in proper healthcare environments.
