This may seem like a silly question, but when the bedding etc is getting changed/thrown out have your grandparents actually been treated for scabies? Have they gotten rid of them and they keep coming back? I think scabies is extremely contagious with direct skin contact and I *personally wouldn't want anyone holding my baby if they had it. I'm not sure though if they are contagious after treatment. I think the treatment is just a cream from neck to toe, maybe ask the chemist and after your grandparents are treated they may not be contagious.. It is extremely sad. Have your grandparents been assessed by ACAT (Aged care Assessment Team)? It sounds like you really need the help of a social worker. I am shocked the hospital hasn't done more to prevent this happening. Surely they are entitled to home help?? I hope your grandparents get the help they deserve. Do you know where the scabies are coming from?

ETA: Are you sure it's scabies they have?
