Which practice is most effective in preventing the spread of infection?

• A. Wash hands between each patient contact
• B. Wear gloves for all patient interactions
• C. Use antibiotics unnecessarily
• D. Isolate patients in separate wards

Answer: (A)

Hand hygiene is the most effective way to prevent the spread of infections. When you wash your hands between patient contacts, you remove or kill the microbes you might have picked up from one patient, so they don’t get carried to the next person or to surfaces. This simple step directly interrupts the main route of transmission in healthcare settings. Alcohol-based hand rubs are great for routine cleaning when hands aren’t visibly dirty, and soap and water are needed when hands are visibly soiled or after contact with potential spores. Gloves are helpful, but they don’t replace hand hygiene—hands should be cleaned before putting gloves on and after removing them to avoid transferring organisms. Using antibiotics unnecessarily can drive resistance and won’t prevent the spread of infections. Isolating patients is important for certain contagious diseases, but it’s not the universal best practice for preventing spread compared with consistent hand hygiene.
