Malarial parasite can be obtained in RBCs of patient

Options

A. during fever
B. before temperature rise
C. after temperature becomes normal
D. all of above

Answer

**Step-by-Step Solution:**

1. **Understanding Malaria**: Malaria is a disease caused by the Plasmodium species, which are transmitted to humans through the bite of infected female Anopheles mosquitoes.

2. **Symptoms of Malaria**: Common symptoms include fever, chills, tiredness, vomiting, and headaches. In severe cases, symptoms can escalate to jaundice (yellowing of the skin), seizures, and even coma.

3. **Timing of Parasite Detection**: The malarial parasites can be detected in the red blood cells (RBCs) of an infected patient. The timing of when these parasites can be found is crucial to answering the question.

4. **Analyzing the Options**:
- **Option A (During fever)**: This is when the body temperature rises due to the immune response to the infection. At this time, the malarial parasites are actively multiplying in the RBCs, making them detectable.
- **Option B (Before temperature rise)**: Before the fever starts, the parasites may not be present in significant numbers in the bloodstream, making them harder to detect.
- **Option C (After temperature becomes normal)**: After the fever subsides, the number of parasites may decrease, making detection less likely.
- **Option D (All of the above)**: This option suggests that parasites can be detected at all times mentioned, which is not accurate based on the understanding of the disease progression.

5. **Conclusion**: The most appropriate answer is **Option A (During fever)**, as this is when the parasites are most likely to be present in the RBCs and can be detected.

**Final Answer**: A. During fever
