The chill and fever experienced by a person suffering from malaria is caused by the rupture of RBCs. This rupture happens when the parasite (Plasmodium) has completed its cycle of multiplication inside the RBCs and releases new forms (merozoites), which enter fresh RBCs. This process leads to the characteristic symptoms of malaria, such as fever and chills.

Understanding Plasmodium Infection
Plasmodium species, which cause malaria, have a complex life cycle involving several stages in both humans and mosquitoes. The symptoms of malaria, particularly chills and fever, are linked to specific events in this life cycle.
Chills and Fever Mechanism
- The primary symptoms of malaria, such as chills and fever, occur during the rupture of red blood cells (RBCs).
- This rupture happens when the parasite, in its asexual stage, has multiplied significantly within the RBCs.
RBC Rupture Process
- As Plasmodium multiplies inside the RBCs, it develops into mature trophozoites and then schizonts.
- When the schizonts reach maturity, they cause the infected RBCs to burst, releasing thousands of new merozoites into the bloodstream.
Release of Merozoites
- The release of merozoites triggers a strong immune response, leading to the release of pyrogens (fever-inducing substances).
- This immune response results in the characteristic chills followed by fever, marking the cyclical nature of malaria symptoms.
Conclusion
- Therefore, the correct answer is option 'C': "The parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs."
- Understanding this mechanism is crucial for recognizing the symptoms of malaria and the importance of timely treatment to prevent severe complications.
