Malarial parasite can be obtained in RBCs of patient

Options

A. When temperature reaches normal
B. An hour before rise in temperature
C. When temperature rises with rigor
D. A few hours after temperature reaches normal

Answer

### Step-by-Step Solution:

1. **Understanding Malaria**: Malaria is a mosquito-borne disease caused by protozoan parasites of the genus *Plasmodium*. The disease primarily affects humans and can lead to severe health complications.

2. **Identifying the Symptoms**: The symptoms of malaria include:
- Fever
- Tiredness
- Vomiting
- Headaches
- In severe cases, it can lead to yellow skin (jaundice), coma, or even death.

3. **When to Obtain the Malarial Parasite**: The malarial parasite can be detected in the red blood cells (RBCs) of an infected patient during specific conditions:
- The parasite is most likely to be found when the patient's body temperature rises significantly, accompanied by chills (referred to as rigor).

4. **Evaluating the Options**:
- **Option 1**: When the temperature reaches normal - Incorrect, as the parasite is not detectable at normal body temperature.
- **Option 2**: An hour before the rise in temperature - Incorrect, as the parasite is not present before the temperature rise.
- **Option 3**: When the temperature rises with rigor - Correct, as this is when the parasite is detectable in the RBCs.
- **Option 4**: A few hours after the temperature reaches normal - Incorrect, as the parasite would not be present at this time.

5. **Conclusion**: The correct answer is **Option 3**: When the temperature rises with rigor.
