Since a person suffering from crusted scabies already has a compromised immune system, the tendency of their skin to flake off puts them at a high risk of contracting bacterial diseases like streptococcal, staphylococcal, impetigo or cellulitis.

Diagnosis and Treatment for Norwegian Scabies

People suspected of having Norwegian scabies should get examined for the presence of mites, mite eggs or mite fecal matter. This can be done by testing the individual’s skin scraping. Scabies can be treated with specific chemical insecticides known as scabicides, which can be applied on the body in the form of creams or lotions. Certain antibiotics may also need to be administered to manage Norwegian Scabies. Since crusted scabies can be tough to heal, the entire treatment process may need to be repeated to get rid of Norwegian Scabies. Keratolytic agents can be used by the patients to remove the affected skin. They can also use the medication called permethrin for over 6 weeks to effectively treat Norwegian Scabies. Another possible treatment for Norwegian scabies is Ivermectin. However, some patients have reported resistance to this medication.

Classical Scabies v/s Norwegian Scabies: Primary Differences

Norwegian scabies is different from normal scabies where in Norwegian scabies; the body’s immune response to itch mites is not strong enough. This allows for the infestation of the body with hundreds or thousands of these mites. Crusted scabies or Norwegian scabies mostly affects people with a compromised immune system and is generally observed in seniors, mentally or physically disabled individuals, and in patients with lymphoma, AIDS, or other conditions which reduce the effectiveness of the immune response. The lesions of Norwegian scabies are extensive and can spread all over the body. The knees, elbows, scalp, palms, and soles are the most common sites for origination of the Norwegian scabies rashes, and these scaly areas eventually start looking like warts. In Norwegian scabies, the fingernails thicken and get discoloured, and there is hardly any itching in this form of scabies. Norwegian scabies is specifically dangerous because the lesions often give way to the development of secondary infections, caused by bacteria like Staphylococcus. Both types of scabies can be treated with topical permethrin cream and the oral medication, Ivermectin. But, while regular scabies is generally treated with one of these medications, Norwegian scabies can require both oral medications and multiple applications of a scabicides cream.
