Which practice prevents the spread of infections?

• A. Pathogenic microorganisms
• B. Health informatics
• C. Support services
• D. Infection control

Answer: (C)

Preventing the spread of infections is achieved through infection control, a set of practices designed to interrupt how pathogens move between people and surfaces. This includes hand hygiene, appropriate use of personal protective equipment, proper sterilization and disinfection, thorough environmental cleaning, safe waste management, and isolating patients when needed. It also involves vaccination programs and ongoing surveillance to catch and limit outbreaks. The other concepts aren’t practices aimed at stopping transmission: pathogenic microorganisms are the agents that cause infections, health informatics focuses on health data and information systems, and support services cover logistical and non-clinical roles. By targeting the ways infections spread and implementing standard precautions, infection control directly reduces transmission.
