Which of the following is not a typical symptom of Murine typhus?

Murine typhus, caused by the bacterium Rickettsia typhi, is primarily transmitted through fleas found on rats. The typical symptoms of murine typhus include fever and chills, muscle aches, and a rash. Fever and chills are common as the body reacts to the infection, and muscle aches often accompany the systemic response to the disease, resulting in malaise and discomfort. Additionally, a rash may develop in some cases, generally appearing a few days after the fever begins.

Diarrhea, however, is not a characteristic symptom of murine typhus. While gastrointestinal symptoms can occur in various infections, they are not part of the classic presentation of murine typhus. Instead, the disease mainly manifests with fever and flu-like symptoms, which distinguishes it from other illnesses that might include gastrointestinal distress as a prominent feature. Therefore, identifying diarrhea as not typical for murine typhus is correct, as it does not align with the core symptoms associated with the disease.
