Which is secondary// intermediate host of Hookworm

Options

A. Bed Bug
B. Sandfly
C. Mosquito
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Hookworm Biology**: Hookworms are nematode parasites that primarily infect humans. They belong to the genus Ancylostoma and include species such as Ancylostoma duodenale and Necator americanus.

2. **Defining Hosts**: In parasitology, a definitive host is the organism that harbors the adult, sexually mature form of the parasite. An intermediate host is one that harbors the larval or immature stages of the parasite.

3. **Identifying the Host of Hookworm**: For hookworms, humans are the definitive host. The adult worms live in the small intestine of humans, where they reproduce and lay eggs.

4. **Life Cycle of Hookworm**: The eggs are excreted in human feces and hatch into larvae in the environment. These larvae can develop into infective forms that penetrate the skin of humans, typically through the feet.

5. **Conclusion on Intermediate Hosts**: According to the life cycle of hookworms, there is no need for an intermediate host. The larvae develop directly from eggs in the environment to infective forms without requiring another organism to complete their life cycle.

6. **Final Answer**: Therefore, the correct answer to the question "Which is the secondary/intermediate host of Hookworm?" is "none of the above."
