I'd suggest you to visit a physician or dermatologist at the earliest. An examination should help in detection of the kind of infection.
Though permethrin application is done for both cases, number of applications can vary with severity. In addition you may prescribed antihistamines (to deal with itching)You may need antibiotics if there is secondary infection too.
The room with all the articles would also need decontamination too prevent reinfection.
