Match List – I with List – II and select the correct answer using code given below:

List – I List – II

A. Itch mite 1. Dengue

B. House fly 2. Kala-azar

C. Mosquito 3. Scabies

D. Sand fly 4. Typhoid fever

Appeared in: UPPSC 2022

Explanation

The correct option correctly pairs each vector with the disease it transmits.
Itch mite (Sarcoptes scabiei) is a parasite that directly causes the skin infestation known as Scabies (A-3).
The common House fly (Musca domestica) is a mechanical vector for numerous diseases, including Typhoid fever, by contaminating food and water (B-4).
Mosquitoes, specifically the Aedes species, are biological vectors that transmit the Dengue virus (C-1).
Sand flies are the vectors for the parasite Leishmania donovani, which causes Kala-azar (visceral leishmaniasis) (D-2).

Option A: This option incorrectly matches Itch mite with Typhoid fever (A-4) and House fly with Scabies (B-3). Itch mites cause scabies, and house flies transmit typhoid.
Option C: This option incorrectly matches Itch mite with Kala-azar (A-2), House fly with Scabies (B-3), Mosquito with Typhoid fever (C-4), and Sand fly with Dengue (D-1). All pairings are incorrect.
Option D: This option incorrectly matches Itch mite with Dengue (A-1) and Mosquito with Scabies (C-3). Itch mites cause scabies, and mosquitoes transmit dengue.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Vector-borne diseases and their causative agents as background academic context rather than a clinical decision trigger.
Understanding vector-disease relationships is fundamental for community health nurses to implement effective prevention and control strategies.
Nursing interventions focus on health education regarding personal hygiene (for scabies), food safety (for typhoid), protection from mosquito bites (for dengue), and environmental sanitation to control vector breeding sites.
A key nursing role is identifying early signs of these diseases and educating the community on seeking timely medical care.

How to Approach the Question

First, analyze the two lists provided in the matching question: List-I contains vectors (disease carriers) and List-II contains diseases.
Try to identify at least one or two pairs that you are certain about. For example, most people know that Mosquitoes transmit Dengue (C-1) and Itch mites cause Scabies (A-3).
Look at the options. Check which options contain both C-1 and A-3. In this case, only option B has this combination.
To confirm, check the other pairs in that option. Option B also has B-4 (House fly -> Typhoid fever) and D-2 (Sand fly -> Kala-azar), which are also correct.
This process of elimination and confirmation helps you arrive at the correct answer efficiently without needing to know every single match initially.
