Scabies is common in Australia, particularly in remote Aboriginal and Torres Strait Islander communities, where high rates are driven by overcrowding and poor living conditions, affecting up to a third or more of children. While less prevalent in general Australian populations, it's a widespread skin condition globally, easily spread by skin-to-skin contact or shared items like bedding, causing intense itching and rashes, and often leading to more serious skin infections like impetigo.
Although less common in Australia, less developed communities are at a higher risk of scabies. For example, up to 50% of children and 25% of adults from the Northern Territory's indigenous community will face this condition at some point in their lives.
Scabies is found in every country but is particularly common in many resource-poor tropical settings, particularly in children and older people. Prevalence among children in these settings may vary from 5% up to 50%. Recurrent infestations are common.
Scabies is caused by infestation of the skin by the burrowing mite Sarcoptes scabiei. Scabies is easily spread through direct skin-to-skin contact with sexual partners and household members, and may also occur by sharing clothing, towels and bedding. Scabies in adults is frequently sexually acquired.
Scabies has a variety of clinical manifestations but typically presents with multiple small, erythematous papules, excoriations, burrows, hives, vesicles, pustules, and blisters, usually on multiple localizations, e.g., sides and webs of the fingers, flexor aspects of the wrists, extensor aspects of the elbows, ...
Symptoms of Scabies
Scabies is not a result of poor personal hygiene, but is contracted through skin-to-skin contact with someone who is infested. People with scabies usually have only 10 or 12 mites on their body.
Close skin-to-skin contact and, less often, sharing clothing or bedding with a person who has scabies can spread the mites. Pets don't spread scabies to humans. The scabies mites that affect animals don't survive or reproduce in people.
Outbreak causes
Scabies is a disease of overcrowding. This means mites spread more easily in places where people come into close contact with each other for extended periods of time – such as schools, universities and prisons.
Infants and children. (Children have a lot of close physical contact with their caregivers, friends, family members and classmates.) People who are elderly, especially those living in nursing homes. Healthcare workers who care for people who aren't aware they have scabies.
If you have never had scabies, symptoms can take up to three to six weeks to appear. However, you can still spread scabies even if you do not have symptoms. If you have had scabies before, symptoms typically appear one to four days after exposure.
You need close skin-to-skin contact with an infected person to catch scabies. The mites live in skin but die after a short time if they are away from the skin. Most cases are probably caught from holding hands with an infected person.
Among countries with the highest rates (DALY burdens per 100,000 people), the top 10 were Indonesia (153·86), China (138·25), Timor-Leste (136·6), Vanuatu (131·59), Fiji (130·91), Cambodia (126·93), Laos (124·96), Myanmar (124·46), Vietnam (123·30), and the Seychelles (122·99) [10].
With the 5% permethrin preparation for treating scabies, a response rate of over 90% is anticipated after a single application, and success can often be improved by a second treatment.
It is also known as the 'seven-year itch' due to its persistent nature of infestation without treatment. Scabies has been in existence for centuries with documented cases dating as far back as Aristotle (384 BC to 322 BC).
Overview. Scabies is caused by the human itch mite (Sarcoptes scabiei var. hominis). The microscopic scabies mite burrows into the upper layer of the skin where it lives and lays its eggs.
The mites pass from person to person when people are in prolonged skin-to-skin contact with each other. The hand is the most common site to be first affected. Sleeping in the same bed, and sexual contact are other common ways of passing on the mite. The risk of scabies spreading in schools is very low.
Scabies is not usually a serious condition, but it does need to be treated. A pharmacist will recommend a cream or lotion that you apply over your whole body, including your scalp and face (apart from the area around your eyes). Let the pharmacist know if you're breastfeeding or pregnant.
The 2 most common treatments for scabies are permethrin cream and malathion lotion. Both medications contain insecticides that kill the scabies mite. Permethrin cream is usually recommended as the first treatment.
Blisters, red lumps or flaky skin on your palms, between your fingers, on your wrists, elbows, feet and genitals. You may also see red stripes on your skin. This is where the mites have dug tunnels. Children up to the age of four can also have itching and blisters on their head.
Scabies usually spreads to sexual partners and household members. Scabies can also spread through contact with the clothes, bedding, or towels of someone who has scabies. Scabies spreads quickly in crowded areas where close body and skin contact is common.
Even though being very clean won't stop you from getting scabies, cleanliness is important for good skin health and so that scratches won't become infected. Remember to wash your hands and shampoo your hair often. Wear clean clothes each day and don't wear other people's clothes. Important reminders about scabies.
Classical Scabies
Diagnosis should be confirmed by a GP or dermatologist. Treatment should be coordinated and carried out simultaneously for all affected individuals, ideally within a 24-hour period.
