What term means the presence of infectious materials on surfaces?

• A. Exposure Incident
• B. Sterilization
• C. Local Infection
• D. Contamination

Answer: (D)

Infection-control terms, contamination refers to infectious materials being present on surfaces, tools, or environments. It describes the condition of a surface that has pathogens on it, which can lead to transmission if not addressed. Sterilization is the process used to kill all microbes on a item, removing contamination but not describing the surface itself. An exposure incident is about a situation where someone may have had contact with infectious material, not about the material being present on a surface. Local infection describes infection arising in a specific body area, not the presence of material on surfaces. So, the term that means infectious materials are on surfaces is contamination.
