How do humans usually contract neurocysticercosis?
- A. the bite of an infected arthropod
- B. exposure to contaminated cat feces
- C. swimming in contaminated water
- D. ingestion of undercooked pork
Correct Answer: D
Rationale: The correct answer is D, ingestion of undercooked pork. This is because neurocysticercosis is caused by the larvae of the pork tapeworm, Taenia solium, which can be contracted by consuming undercooked pork containing the cysts. The other choices are incorrect because neurocysticercosis is not transmitted through arthropod bites, exposure to contaminated cat feces, or swimming in contaminated water. It is crucial to thoroughly cook pork to prevent this parasitic infection.
