Which discipline focuses on preventing the spread of infections within a health care facility?

• A. Infection control
• B. Epidemiology
• C. Environmental health
• D. Occupational safety

Answer: (A)

Preventing the spread of infections within a health care facility is the focus of infection control. This discipline designs and runs programs to stop transmission of pathogens among patients and staff, using standard precautions (hand hygiene, appropriate use of gloves and PPE) and transmission-based precautions for suspected or confirmed infections. It oversees cleaning, disinfection, and sterilization of equipment, safe handling and disposal of waste, and safe injection practices. It also manages isolation protocols, patient cohorting, and vaccination programs for health care workers. Surveillance for health care–associated infections, outbreak investigation, and ongoing staff education with compliance monitoring are core parts of the work. Epidemiology studies how infections occur and spread in populations and informs infection control, but its broader scope isn’t focused on implementing prevention programs inside a single facility. Environmental health addresses factors like water, air, and surface quality, while occupational safety protects workers from hazards; neither centers on preventing infections from spreading within the health care setting as directly as infection control.
