scabies

Scabies are not very contagious after first treatment - first treatment is usually considered curative unless some special circumstance like Norwegian scabies. However, linens can be a vector of transmission if not properly cleaned. Also, incubation period is typically 4 to 6 weeks, so itching at ten days is not typical. Since you are a floater, however, you need to consider the other people you come in contact with and should have any rashes evaluated by your primary care.
