Which term describes the indirect transfer of bacteria, viruses, or HIV between patients due to improper sterilization and reusing products?

• A. Cross Contamination
• B. Crown
• C. Decalcification
• D. Diagnosis

Answer: (A)

Cross contamination describes the indirect transfer of pathogens from one patient to another through contaminated instruments, surfaces, or reusable materials that aren’t properly sterilized or are reused between patients. In a dental setting, when items that should be sterilized between uses aren’t, or when barriers aren’t used, microbes can move from one patient to the next via these intermediaries. This concept is about how infection control failures create pathways for bacteria, viruses, and other pathogens to spread. The other terms don’t fit this scenario: a crown is a tooth restoration, decalcification is mineral loss from enamel, and diagnosis is identifying a disease or condition.
