In one of the following diseases, fever must not be managed using Aspirin, instead Paracentamol is used. Which is the one?

Options

A. Chikungunya
B. Filariasis
C. Penumonia
D. Dengue fever

Answer

To determine which disease requires the use of paracetamol instead of aspirin for managing fever, we need to analyze the effects of aspirin and the characteristics of the diseases mentioned.

### Step-by-Step Solution:

1. **Understand the Function of Aspirin**:
- Aspirin is known for its properties as a blood thinner. It reduces the clotting ability of blood and is often used to prevent heart attacks.

2. **Identify the Diseases**:
- The question involves four diseases: Chikungunya, Filariasis, Pneumonia, and Dengue Fever.

3. **Analyze Each Disease**:
- **Chikungunya**: This disease does not significantly affect blood platelet levels, so using aspirin is generally safe.
- **Filariasis**: Similar to Chikungunya, there is no significant risk to platelet levels, allowing for aspirin use.
- **Pneumonia**: Aspirin can be used here as well, as it does not pose a risk to clotting ability.
- **Dengue Fever**: This disease is characterized by a significant reduction in platelet count. The low platelet levels mean that the blood's ability to clot is already compromised.

4. **Conclusion**:
- Given that aspirin further reduces platelet count and clotting ability, it should not be used in Dengue Fever. Instead, paracetamol is recommended for managing fever in this condition.

### Final Answer:
The disease in which fever must not be managed using Aspirin, instead Paracetamol is used, is **Dengue Fever**.
