Solution Analysis: Matching Diseases and Vectors
Understanding the Question
The question requires matching diseases listed in List-I with their corresponding vectors or intermediate hosts listed in List-II. This involves understanding the transmission mechanisms of common vector-borne diseases.
Detailed Breakdown of Matches
Let's analyze each disease and its vector:
- A. Schistosomiasis: This disease, also known as bilharzia, is caused by parasitic flatworms. Humans get infected when larval forms of the parasite—released by freshwater snails—penetrate the skin. Therefore, the intermediate host is the Water Snail (II).
- B. Lymphatic Filariasis: Commonly known as elephantiasis, this disease is caused by filarial worms. It is primarily transmitted through the bites of infected mosquitoes. Thus, the vector is Mosquito (IV).
- C. Leishmaniasis: This disease is caused by protozoan parasites transmitted to humans through the bite of infected female phlebotomine sand flies. Therefore, the vector is the Phlebotomine Sand Fly (I).
- D. Onchocerciasis: Also known as river blindness, this disease is caused by a parasitic worm. It is transmitted through the bite of infected black flies (genus Simulium). Hence, the vector is the Black Fly (III).
Disease-Vector Matching Summary
Based on the analysis, the correct pairings are:
| List-I (Disease) | List-II (Vector/Host) |
| A. Schistosomiasis | II. Water Snail |
| B. Lymphatic Filariasis | IV. Mosquito |
| C. Leishmaniasis | I. Phlebotomine Sand Fly |
| D. Onchocerciasis | III. Black Fly |
Conclusion
Matching the elements correctly gives us: A-II, B-IV, C-I, D-III. This corresponds to the third option provided in the question.
