What symptom is NOT typically associated with influenza?

Chronic diarrhea is not typically associated with influenza. Influenza primarily presents with respiratory symptoms and systemic signs such as fever, chills, headaches, and body aches. The virus targets the respiratory system, leading to symptoms like cough, sore throat, and runny or stuffy nose, alongside the more systemic manifestations.

While gastrointestinal symptoms can occur with other viral infections, chronic diarrhea is not a hallmark symptom of influenza. Acute gastrointestinal symptoms, such as nausea or vomiting, might occasionally occur, especially in children, but chronic diarrhea is beyond the expected scope of influenza-related symptoms and suggests an alternative diagnosis or condition. Thus, identifying chronic diarrhea as a symptom not typically associated with influenza aligns with the standard understanding of the disease's presentation.
