Question

Which stage of malaria parasite causes recurrence of malaria?

• A. Merozoite
• B. Sporozoite
• C. Gametocyte
• D. Hypnozoite

Answer 1

The correct option is D Hypnozoite

Malaria is a mosquito-borne infectious disease affecting humans and other animals caused by Plasmodium species. Symptoms of malaria can recur after varying symptom-free periods. Relapse is when symptoms reappear after the parasites have been eliminated from blood but persist as dormant hypnozoites in liver cells. Relapse commonly occurs between 8–24 weeks and is often seen in P. vivax and P. ovale infections.

So, the correct answer is 'Hypnozoite'.
