Which of the following was NOT listed as an indirect exposure pathway in the African Dwarf Frog outbreak?

• A. Direct contact with infected animals
• B. Exposure to contaminated water, habitats
• C. Other aquatic pets
• D. Environmental contamination in the kitchen

Answer: (A)

Indirect exposure pathways involve transmission through an intermediate medium rather than by touching the infected animal itself. In this outbreak, items like exposure to contaminated water or frog habitats, contact with other aquatic pets, and environmental contamination in the kitchen are indirect routes because the pathogen moves through water, surfaces, or additional animals. Direct contact with infected animals is a direct exposure route, since transmission occurs through physical touch or contact with the animal or its secretions without an intermediary medium. Because the question asks for what was NOT listed as an indirect exposure pathway, direct contact is the correct distinction: it is not an indirect route.
