Fever in Malaria is due to

• A. Entry of crypto merozoites into red blood corpuscles.
• B. Entry of sporozoites into blood capillaries.
• C. Entry of merozoites from red blood corpuscle.
• D. Release of merozoites from red blood corpuscles.

Fever in malaria is primarily caused by the release of merozoites from red blood corpuscles. When the malaria parasite, specifically Plasmodium, invades red blood cells, it multiplies and eventually bursts the cells, releasing merozoites into the bloodstream. This release triggers an immune response, leading to fever.

Key Points to Remember

• Merozoites: These are the forms of the malaria parasite that infect red blood cells.
• Immune Response: The body's reaction to the release of merozoites causes fever.
• Cycle of Infection: The cycle continues as merozoites infect more red blood cells.

Therefore, the correct answer is D. Release of merozoites from red blood corpuscles.
