The Widal test is a blood test used to diagnose typhoid fever, which is caused by the bacterium Salmonella typhi. This test detects the presence of antibodies in the blood that are specifically produced in response to the Salmonella typhi bacteria.

Option 1, Salmonellosis, is not the correct answer. Salmonellosis is a bacterial infection caused by other Salmonella species and is different from typhoid fever.

Option 2, Malaria, is also incorrect. Malaria is caused by the parasite Plasmodium and is diagnosed using different laboratory tests.

Option 3, Cholera, is not the correct answer either. Cholera is caused by the bacterium Vibrio cholerae and is diagnosed by detecting the presence of the bacteria in stool samples.

Therefore, the correct answer is option 4, Typhoid, as the Widal test is specifically used to diagnose typhoid fever caused by Salmonella typhi.
