Crusted scabies

Overview

Type of disease: Rare conditions

Crusted scabies (also called Norwegian scabies) is a severe form of scabies that most often occurs in people who have a weakened immune system, neurological disease, the elderly, the disabled, or those who are mentally incapacitated. It is characterized by thick crusts of skin that contain large numbers of scabies mites and eggs. The usual features of scabies (itching and a rash) are often absent. Crusted scabies  is very contagious and can spread easily both by direct skin-to-skin contacts and through contaminated items such as clothing, bedding, and furniture. People with crusted scabies should receive quick and agressive medical treatment for their infestation to prevent outbreaks of scabies. Ivermectin is commonly used to treat this form of scabies.
