Which of the following symptoms are associated with Typhoid fever?

Typhoid fever is a serious illness caused by the bacterium Salmonella typhi, and its symptoms typically include fever, headache, and abdominal pain. The fever is often sustained and can be high-grade, while headaches are common due to systemic infection. Abdominal pain can arise from intestinal complications associated with the illness or inflammation of the intestinal lining.

This combination of symptoms is characteristic of typhoid fever, as the illness primarily presents with systemic manifestations reflecting the body's response to the infection. While other options list symptoms that may arise from different illnesses or conditions, they do not accurately represent the primary clinical picture of typhoid fever, which is well-defined by the trio of fever, headache, and abdominal pain.
