What is the most important factor in preventing the spread of infection?

• A. Wear gloves at all times
• B. Use hand sanitizer after touching surfaces
• C. Wash hands between each patient contact
• D. Sterilize all equipment between patients

Answer: (C)

Hand hygiene between patient contacts is the most effective way to prevent the spread of infection. Hands are the primary vehicle for transferring pathogens from one patient to another and to healthcare workers, so cleaning them thoroughly between patient encounters interrupts transmission at its most common point. Gloves have a role in certain situations, but they’re not a substitute for washing or sanitizing hands, since gloves can have tiny gaps and may become contaminated during removal. Using sanitizer after touching surfaces helps, yet it isn’t always sufficient, especially if hands are visibly dirty or contaminated from direct patient care. Sterilizing all equipment between patients isn’t feasible for routine care and isn’t the single most important factor in preventing spread; standard hand hygiene between patients consistently reduces cross‑infection risk across a wide range of care activities.
