The terms “typhoid” and “typhoid fever” actually refer to the same disease — there’s no medical difference between them. The full name is typhoid fever, caused by the bacterium Salmonella enterica serotype Typhi, but people commonly shorten it to “typhoid.” The word “fever” highlights the key symptom — a prolonged, high-grade fever — but both terms describe the same systemic infection that affects multiple organs, particularly the intestines, liver, and spleen. So, using “typhoid” or “typhoid fever” is correct; the former is just an informal, shorter version of the medical term.
