Overview

Parasitic skin infestations occur when parasites find ways to penetrate into the skin to live and lay their eggs on the skin or live in clothing or bedding and periodically biting human skin. Some parasites can be spread by people sleeping in the same bed, sharing clothing or close contact.

Symptoms and signs

Symptoms can include rash and lumps and inflammation. Scabies are too small to be seen by the naked eye but head lice and crabs may be seen moving on the skin.

Treatment

Treatment is dependent on the type and extent of infestation. It can include the use of medicated shampoos, creams or lotions, which may require a prescription and these need to be used according to set instructions to ensure complete eradication. Treatment to clothing and bedding may be required, as well as the treatment of other family members.
