Answer:
There are many NOT typical symptoms of influenza, since the typical ones are very pathognomonic.
Those that are not typical could become:
that the patient feels animated, not very fatigued, with excess energy and absence of fever, insstinal constipation.
Explanation:
The symptoms, unlike the signs, are what the patient perceives ... That is why we do not clarify other factors such as dyspnea or fever, since that would become a SIGN and not a SYMPTOM.
Instead, the sign is a factor that appears and is perceived by the medical professional through some technique or thanks to some prior knowledge.
