My room mate has had body lice for 2 1/2 months now. The dr. s are calling this a major infestation. I am so paranoid that I or my children will catch this. We have all gone to the Doctors office and received the permetrin cream about a month ago. She can t seem to get rid of the bugs and it is driving her into an obsessive/compulsive spin. Is there a medical condition that wold make her body not be able to respond to Permetrin? At this point should I treat my 10 yr old twins again? I don t know what to do, I am constantly looking for signs of lice on myself. She has either thrown away all of her clothing or bagged it up and put it in the garage.
