The signs and symptoms of influenza can start randomly after one to four days of incubation. Barring chills in some cases, the first noticeable symptom is a sudden, high temperature, generally 100-103°F. It is not uncommon for the fever to be so debilitating that people are confined to bed for several days. Other symptoms of influenza may include;
-Headache
-Cough
-Nasal Congestion
-Sore Throat
-Fatigue
-Irritated Eyes
-Aches and pains
-Reddened eyes, mouth, throat, nose and skin
Note that gastrointestinal symptoms such as nausea, vomiting, and diarrhea may appear in children, but are uncommon in adults.
