In infection prevention, what is the single most effective action to prevent transmission?

• A. Proper hand hygiene.
• B. Wearing gloves at all times.
• C. Using antibiotics prophylactically.
• D. Isolating all patients.

Answer: (A)

Hand hygiene is the most powerful way to stop the spread of infections because hands are the main vehicle that moves pathogens between people and surfaces. Clean hands at the right times—before touching a patient, after any contact with potentially contaminated surfaces, after removing gloves, and after patient care—greatly reduce the chance of transmitting germs. Using gloves all the time isn’t practical and can fail to prevent transmission if hands aren’t cleaned properly during glove changes. Prophylactic antibiotics don’t prevent the spread of infection and can lead to resistance, while isolating every patient is not feasible in most settings. So, clean hands at the right moments make the biggest impact.
