7 year old threw up twice within 4 hours. says she has to pee a lot. no fever or very slight (99). uti? or virus?

It's Something...: I have two thoughts about this brief mention of your child's symptoms... 1. Yes she definitely could have a UTI, a urinalysis and Urine culture are in order. 2. "peeing a lot" could also be a sign of diabetes presentation in a child, so we definitely need that urine test, which will show if there is sugar in there indicative of diabetes warranting blood work.
