1 year daughter teething, vomiting! need opinion?

I have two girls and that definitely sound like more than tething. Not to scare you but have you ever herd of rota virus? Its a virus and it is vielent and very scarey and could be fatal. Both my girls had it and they were in the hospital for two weeks, she had to have i-v's. If she is vomiting, has a fever, acts like she just cant move, and it has been more than two days and she cant even keep a popsickle dow or her drink, take her to the hospital. Dont listen to the doctor if you know there is something wrong.
