Primary host of Guinea Worm is

Options

A. Cyclops
B. Man
C. Fish
D. Antelope

Answer

**Step-by-Step Solution:**

1. **Understanding Guinea Worm Disease**: Guinea worm disease is caused by a parasitic worm known as Dracunculus medinensis. This parasite primarily affects humans.

2. **Identifying Hosts**: In parasitology, hosts are classified into primary and secondary hosts. The primary host is the organism that harbors the adult form of the parasite, while the secondary host is where the juvenile or larval stages of the parasite develop.

3. **Determining the Primary Host**: In the case of the Guinea worm, the primary host is humans (man). The adult female Guinea worm grows inside the human body and eventually emerges through the skin, causing painful sores.

4. **Identifying the Secondary Host**: The juvenile stages of the Guinea worm live in freshwater and infect tiny crustaceans known as copepods (for example, Cyclops). These copepods act as the secondary host for the juvenile stages of the worm.

5. **Conclusion**: Therefore, the primary host of the Guinea worm is humans (man), while the secondary host is the copepods.

**Final Answer**: The primary host of Guinea Worm is **man**.
