My niece has fever, aches everywhere, sore throat and coughing! she says it feels like the flu but we didn't think it was the time of year for the flu! what do u think this could be?

Flu like illness...: Or, it could be the flu. The signs of flu are just what you list: sudden onset of fever, body aches, and severe cough, plus or minus other symptoms like sore throat, vomiting, headache, etc.. There are, however, other things it could be, so if it goes on longer than a couple of days, it's best to have her looked at by a doctor.
