Osler on typhoid fever: differentiating typhoid from typhus and malaria.
Early in the history of medicine, physician had a difficult time differentiating acute febrile illnesses without localizing signs. Typhoid fever and malaria share common features, which caused diagnostic problems during the 1800s. Physician even introduced a new term, typho-malaria, a testimony to their diagnostic confusion. Osler, consummate clinician and careful observer, had vast experience with typhoid fever and malaria. He was able to easily discern between the key features of both of these infections. He also relied on fever patterns to clearly differentiate typhoid fever from malaria. Osler is credited for debunking the term typho-malaria. His clinical description of typhoid fever remains unsurpassed. Clinicians still can benefit greatly from reading Osler's clinical description of typhoid fever.
