What are the symptoms of the flu?

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.
