Which term describes methods used to eliminate or reduce the transmission of infectious organisms from one individual to another?

• A. Infection control
• B. Sterilization
• C. Immunization
• D. Quarantine

Answer: (A)

The question is testing infection control measures used to prevent the spread of infection from one person to another. Infection control describes the practices and procedures that reduce or eliminate opportunities for pathogens to move between people, especially in settings like clinics and salons, but also in daily life. This includes things like proper hand hygiene, using personal protective equipment, cleaning and disinfecting surfaces, sterilizing instruments, and isolating or managing individuals who are contagious.

Why infection control fits best: it specifically covers the broad set of methods aimed at breaking the chain of transmission, from everyday habits to targeted interventions. Sterilization, while important, refers to removing all microorganisms from objects and is just one technique within a broader infection-control program. Immunization protects individuals by building immunity through vaccines, which can reduce disease and sometimes transmission but is not about the general practices used to stop spread in all contexts. Quarantine involves separating potentially exposed individuals to prevent spread, but it’s a specific strategy rather than the overall system of practices designed to prevent transmission in general. Together, infection control encompasses the comprehensive approach to minimizing transmission between people.
