My 2 year old daughter has this bad caugh and fever for a week now. Her dr checked her urine and blood count, it was all normal. So what is wrong?

Hard to tell. If those symptoms are continuing and not resolving, then re-checking with md to re-evaluate and examine her would be the best advice... Viral infections can mimic bacterial for the first 3-7 days of an illness, but after that - i always want to re-check and look closer... If not getting better...
