Question

(a) Why do the symptoms of malaria not appear in a person immediately after being bitten by an infected female Anopheles? Give one reason. Explain when and how do the symptoms of the disease would appear.
 

Hint:

The incubation period of malaria allows the parasite to multiply in liver cells before invading red blood cells, causing symptoms.

Answer 1

- The sporozoites take time to multiply in the liver cells before infecting red blood cells, which delays the onset of symptoms. 
- Symptoms like fever, chills, and sweating appear when the parasite ruptures red blood cells and releases toxins into the bloodstream.
