What is the best method to prevent transmission of disease in a clinical setting?

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

Answer: (B)

Hands are the main vehicle for spreading infections in a clinical setting. Regular hand hygiene—washing with soap and water or using an alcohol-based hand sanitizer—physically removes or kills pathogens and dramatically lowers the risk of transmitting organisms between patients, staff, and the environment. Do it before touching a patient, after contact with a patient or their surroundings, after removing gloves, and after exposure to bodily fluids. Other options fall short: cleaning surfaces with water alone doesn’t kill most pathogens; routinely taking antibiotics isn’t a preventive measure for transmission and can drive resistance; gloves help during specific tasks but don’t replace the need for hand hygiene and must be used in conjunction with proper hand hygiene. Therefore, handwashing is the most effective method to prevent transmission.
