Which action is most effective at preventing the spread of infection in a clinical setting?

• A. Handwashing
• B. Disinfecting surfaces with water only
• C. Taking antibiotics routinely
• D. Wearing gloves

Answer: (A)

Hands are the main way infections spread in a clinical setting. Regular hand hygiene—washing with soap and water or using an alcohol-based sanitizer—removes and inactivates the microbes on your hands, cutting the chance of transmitting pathogens to patients, staff, or surfaces. This single action has the greatest impact on reducing cross-infection. Disinfecting surfaces with water alone doesn’t work because water doesn’t kill or reliably remove many pathogens; proper disinfectants and adequate contact time are needed. Taking antibiotics routinely isn’t a preventive measure for transmission and can lead to resistance and other harms. Wearing gloves helps protect against contact transmission, but it isn’t sufficient by itself—hands should be cleaned before putting on gloves and after removing them to ensure all potential contaminants are removed.
