Recurrent high fever in malaria is due to completion of

Options

A. Erythrocytic schizogony
B. Sporogony
C. Gamogony
D. Exoerythrocytic schizogony

Answer

**Step-by-Step Solution:**

1. **Understanding Malaria and Plasmodium Life Cycle**: Malaria is caused by the Plasmodium parasite, which has a complex life cycle that includes both asexual and sexual phases. The asexual phase occurs in humans, while the sexual phase occurs in mosquitoes.

2. **Infection Process**: The cycle begins when an infected female Anopheles mosquito bites a human and injects sporozoites into the bloodstream. These sporozoites travel to the liver.

3. **Exoerythrocytic Cycle**: Once in the liver, the sporozoites undergo a phase called the exoerythrocytic cycle, where they multiply and develop into merozoites.

4. **Erythrocytic Cycle**: The merozoites then enter the bloodstream and invade red blood cells (RBCs). Inside the RBCs, they undergo further multiplication in a phase known as erythrocytic schizogony.

5. **Symptoms of Malaria**: The clinical symptoms of malaria, such as recurrent high fever, chills, and other manifestations, appear after the completion of the erythrocytic schizogony phase. This is because the rupture of the RBCs releases toxins into the bloodstream, leading to fever.

6. **Conclusion**: Therefore, the recurrent high fever in malaria is due to the completion of the erythrocytic schizogony phase.

**Final Answer**: The recurrent high fever in malaria is due to the completion of erythrocytic schizogony.
