Question

Which one of the options given best matches vector to disease? \begin{center} \begin{tabular}{|l|l|} \hline Vector & Disease
\hline I. Fleas & P. Kyasanur Forest Disease
II. Ticks & Q. Dengue
III. Mosquitoes & R. Plague
\hline \end{tabular} \end{center}

• A. I-R; II-P; III-Q
• B. I-P; II-R; III-Q
• C. I-R; II-Q; III-P
• D. I-R; II-P; III-R

Hint:

To remember vector-disease associations: 1. Fleas are primarily associated with the plague.
2. Ticks transmit tick-borne diseases like Kyasanur Forest Disease.
3. Mosquitoes are vectors for viral diseases like dengue, malaria, and Zika.

Answer 1

The Correct Option is A

Step 1: Understand the relationships between vectors and diseases. Vectors are organisms that transmit pathogens or diseases from one host to another. The correct relationships are: I. Fleas (R. Plague): Fleas are known vectors for the plague, specifically the bacterium \textit{Yersinia pestis}. I. Ticks (P. Kyasanur Forest Disease): Ticks are vectors for Kyasanur Forest Disease, a tick-borne viral hemorrhagic fever. III. Mosquitoes (Q. Dengue): Mosquitoes, particularly \textit{Aedes aegypti}, are vectors for dengue fever, a viral disease. Step 2: Analyze the options. Option (A): Correct. Matches I-R, II-P, and III-Q correctly. Option (B): Incorrect. Misassigns fleas (I) to Kyasanur Forest Disease (P). Option (C): Incorrect. Misassigns ticks (II) to dengue (Q). Option (D): Incorrect. Misassigns mosquitoes (III) to plague (R).
