Scarey Painful Rashes

My granddaughter is in foster care and came up with a horrible rash inside her genital area. It looks like cauliflower she never says owie and now she says owie..so it hurts her, it has spread down her legs inside and now she has scratches and scars on her rear end. What kind of rashes are these? We are not aloud to take her to the hospital ..the care taker was ordered for 1 week now and has not complied. We are devastated and scared to death what is going on. :(
