Crusted scabies

People with crusted scabies may have extreme infestations with tens of thousands of mite.

Crusted scabies, formerly known as Norwegian scabies, is a more severe form of the infection often associated with immunosuppression.

Also called Norwegian scabies, crusted scabies is a very severe infestation involving tens of thousands of mites on a single person.

Sufferers of crusted scabies exhibit scaly rashes, slight itching, and thick crusts of skin that contain thousands of mites.

The elderly and people with an impaired immune system, such as HIV, cancer, or those on immunosuppressive medications, are susceptible to crusted scabies (formerly called Norwegian scabies).

Since mites can only survive for two to three days without a host, objects in the environment pose little risk of transmission except in the case of crusted scabies, thus cleaning is of little importance.

A more severe and uncommon form of the condition occurs when there are many mites in the skin - this is called crusted scabies, and can affect older people and people with certain illnesses, such as HIV.
