Options

A. Pneumonia
B. Malaria
C. Typhoid
D. Cholera

Answer

**Step-by-Step Solution:**

1. **Understanding the Widal Test**: The Widal test is a serological test used to diagnose typhoid fever. It detects the presence of specific antibodies (agglutinins) against the bacteria Salmonella typhi in the patient's serum.

2. **Identifying the Disease**: The primary disease associated with the Widal test is typhoid fever, which is caused by the bacterium Salmonella typhi. This disease is characterized by prolonged fever, abdominal pain, and loss of appetite.

3. **Analyzing Other Options**:
- **Pneumonia**: This is primarily diagnosed through clinical symptoms and imaging (like X-rays), not the Widal test.
- **Malaria**: This is diagnosed through blood tests that detect the presence of Plasmodium parasites, not the Widal test.
- **Cholera**: This is a waterborne disease diagnosed through stool tests and clinical symptoms, not the Widal test.

4. **Conclusion**: Since the Widal test is specifically used for detecting typhoid fever, the correct answer to the question is that the Widal test is employed for detecting typhoid.

**Final Answer**: The Widal test is employed for detecting typhoid.
