Scabies is a common, yet neglected, skin disease. Scabies occurs across Australia, but most frequently in socioeconomically disadvantaged populations in tropical regions, including in remote Aboriginal and Torres Strait Islander communities.
Scabies is spread by prolonged skin-to-skin contact with a person who has scabies. Scabies sometimes also can be spread by contact with items such as clothing, bedding, or towels that have been used by a person with scabies, but such spread is very uncommon unless the infested person has crusted scabies.
Scabies is most commonly passed through prolonged skin-to-skin contact but can also be spread through infested bedding, clothing, furniture, or towels. People who live in crowded quarters or are caregivers in places like nursing homes are at greater risk.
For items that cannot be washed, store in a sealed plastic bag for at least 72 hours to kill any mites. Vacuum and clean rooms and furniture used by the person with scabies. This is especially recommended in the case of crusted scabies. The use of insecticides is not recommended for environmental control.
You also can't usually get scabies from toilet seats. Most of the time, it takes lots of close, personal contact with an infected person for scabies to spread.
The infestation may last for years without treatment and has been called the seven year itch. This is a photomicrograph of scabies feces in skin scrapings.
