2. **Identifying the Disease**: The primary disease for which the Widal test is performed is typhoid fever. Typhoid fever is a serious illness caused by the bacterium Salmonella typhi.

3. **Characteristics of Typhoid Fever**:
- Typhoid fever is a bacterial disease.
- It is caused by Salmonella typhi, which is a Gram-negative bacterium.

4. **Transmission of the Disease**: The bacteria typically enter the body through contaminated food and water, primarily affecting the small intestine and can spread to other organs.

5. **Symptoms of Typhoid Fever**: Common symptoms include:
- Sustained high fever (39°C to 40°C)
- Weakness
- Stomach pain
- Constipation
- Headache
- Loss of appetite
- In severe cases, it may lead to intestinal perforation and can be fatal.

6. **Confirmation of Diagnosis**: The diagnosis of typhoid fever is primarily confirmed through the Widal test, which detects the antibodies produced in response to the infection.

7. **Conclusion**: Therefore, the Widal test is performed specifically for diagnosing typhoid fever.
