hello its urinary tract infection probably and vermox was given to deworm as worms are a commonest cause of UTI in children especially in repeated episodes. secondly in females hygiene is an issue. i would advise wiping from front to back while washing after peeing and to avoid tight clothing and constipation.if she has constipation and has pain during pooping also,get her checked for anal fissure .go for a repeat urine routine examination and culture test and also a kidney ultrasound to rule out any anatomical pathology.
