Explanation

To answer the question regarding one of the common symptoms observed in people infected with Dengue fever, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Dengue Fever**: Dengue fever is a viral infection transmitted by mosquitoes, primarily the Aedes aegypti mosquito. It can lead to severe flu-like symptoms.

2. **Identify Common Symptoms**: The common symptoms of Dengue fever include high fever, severe headache, pain behind the eyes, joint and muscle pain, rash, and mild bleeding. However, one of the most critical symptoms is related to blood components.

3. **Focus on Platelet Count**: In patients with Dengue fever, one of the significant changes observed is a decrease in platelet count. Platelets are essential for blood clotting, and a low platelet count can lead to serious complications.

4. **Normal Platelet Count**: In a healthy individual, the normal platelet count ranges from approximately 300,000 to 350,000 platelets per microliter of blood. In Dengue patients, this count can drop significantly.

5. **Life-Threatening Condition**: A drastic decrease in platelet count can lead to a life-threatening condition known as Dengue Hemorrhagic Fever, which can cause bleeding and shock.

6. **Conclusion**: Therefore, the common symptom observed in people infected with Dengue fever is a significant decrease in platelet count.

### Final Answer:
The common symptom observed in people infected with Dengue fever is a significant decrease in platelet count.
