Which symptom is NOT typically associated with Shigella infection?

Shigella infections are primarily known for causing gastrointestinal symptoms. The hallmark symptoms include diarrhea, which can often be bloody, as well as fever and abdominal cramping. Nausea is also a common symptom that can accompany the diarrhea due to the inflammatory effects of the bacteria in the intestinal lining.

Headaches, while they can occur as a general symptom in many illnesses, are not specifically characteristic of Shigella infections. The primary presenting symptoms relate more closely to gastrointestinal distress rather than systemic symptoms like headaches. Therefore, identifying headaches as a symptom not typically associated with Shigella infection aligns with the understanding of the most common clinical presentation of this type of infection.
