Which of the following conditions is caused by a protozoan parasite?
Appeared in: NORCET-11 Prelims
Explanation
- Kala-azar is caused by Leishmania donovani, a protozoan parasite.
- Leishmania donovani is transmitted by sandflies and causes visceral leishmaniasis.
- Other options are caused by viruses (dengue, chikungunya) or bacteria (leptospirosis), not protozoa.
Why Other Options Were Wrong
- Option A: Dengue is caused by a virus, not a protozoan parasite.
- Option B: Chikungunya is caused by a virus, not a protozoan parasite.
- Option D: Leptospirosis is caused by a bacterium, not a protozoan parasite.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of diseases caused by protozoan parasites as background academic context rather than a clinical decision trigger.
- Nurses must recognize kala-azar as a protozoan disease for accurate diagnosis and reporting, especially in endemic regions.
- Early identification and treatment are crucial to prevent fatal complications such as severe anemia and secondary infections.
- What if? If the question asked for a viral disease transmitted by mosquitoes, dengue or chikungunya would be correct instead.
How to Approach the Question
- Read each option and recall the causative organism (virus, bacteria, protozoa).
- Eliminate options known to be viral or bacterial based on textbook knowledge.
- Identify the disease associated with protozoan parasites (Kala-azar/Leishmania donovani).
- Confirm with clinical features or transmission method if unsure.
