My 3 year 9 month old son has had fever (99-100 during the day, 100-102 at night) and diarrhea (but, he frequently has loose stools and has multiple food intolerances) for 5 days now.  His fever goes down in the day and his energy level is normal except he is a little more whiny than normal and he has very little appetite.  His sleep has been broken since the fever goes up at night.  I havent given him any fever reducers. His lips are getting pretty chapped.  My nephew was diagnosed with type b infuenza on monday and we played with him over the weekend.  At first I was fairly certain we got sick from him, but Im concerned about his lips starting to crack and the duration.  Is lip cracking normal for the flu and is ?
Hi.... cracking of lips is not a sign of thermophilous B influenza infection. You need not worry about it. By what you say I feel that your kid is going through a viral illness. I will explain to you how a viral illness behaves, so that you can be more confident. Fever of few days without any localizing signs could as well a viral illness. Usually rather than fever, what is more important is the activity of the child, in between 2 fever episodes on the same day. If the kid is active and playing around when there is no fever, it is probably viral illness and it doesn't require antibiotics at all. Once viral fever comes it will there for 4-7 days. So do not worry about duration if the kid is active. Regards -
