High Priority Alert. Close alert. Informational Alert. Scabies-Itch Mite Rash. Is this your child's symptom? A very itchy rash caused by the scabies mite A mite is a tiny, invisible bug that burrows under the skin A doctor has told you your child has scabies or Your child has had close contact with another person who has it Symptoms of Scabies Widespread little red, bumpy rash that mainly involves the skin folds. Intense itching is the main symptom.

If it doesn't itch, it's not scabies. The rash is often most obvious on the inside of the thighs, parts of the abdomen and buttocks, the armpits and around the nipples in women. The appearance of the rash is often typical. However, some people develop unusual rashes which may be confused with other skin conditions. Scratching due to intense itching can cause minor skin damage.

In some cases the damaged skin becomes infected by other germs bacteria. This is a secondary skin infection. If skin becomes infected with bacteria it becomes red, inflamed, hot, and tender. Scabies can worsen the symptoms of other skin conditions, particularly itchy skin problems such as eczema , or problems such as psoriasis. Scabies can be more difficult to diagnose in these situations too.

Note : the itch and rash of scabies are due to a reaction allergy to the mites or their saliva, poo faeces or eggs. Scabies symptoms usually take weeks to occur after you are first infected. The itch and rash can develop on any part of the skin, away from where the mites are actually burrowing.

This means that you are infectious and can spread scabies before you even know you have scabies. The itch and rash normally take weeks to develop when you have a first scabies infection.

However, if you have scabies and it is cleared with treatment, and then you catch it again, the symptoms may be slightly different. In such instances the rash and itching develop much more quickly - often within a day or two. This is because the first scabies infestation has already sensitised your immune system.

It then reacts much more quickly with this second bout of scabies. You need close skin-to-skin contact with an infected person to catch scabies.

This is because the scabies mite cannot jump or fly. Most cases of scabies are probably caught from prolonged hand-holding with an infected person. The hand is the most common site to be first affected. The skin-to-skin contact needs to be for a reasonable time to catch the mite. You usually need to be in skin contact for minutes to catch scabies. Therefore, you are unlikely to catch scabies from an infected person by casual short contact such as a handshake or a hug.

The more mites there are, the faster they can spread to another person. The mites live in skin and can survive away from the host human for about hours. You are unlikely to catch scabies from bedding and towels unless you use them immediately after being used by someone with scabies.

However, just in case, it is best to treat bedding and towels by hot washing described later. Scabies is fairly common and can usually be recognised and treated by GPs. In the UK, about 1 in 1, people develop scabies each month. Scabies is more common in town urban areas, in women and children and in the winter because people often share beds in the cold. It is common worldwide, particularly where there is poverty and overcrowding such as poor areas of Asia and Africa.

There may be outbreaks in overcrowded places such as refugee camps. Sometimes outbreaks of scabies occur in places such as nurseries and residential homes, where people are in regular close contact. This type of scabies is unusual, and most people who develop scabies do not get 'Norwegian' scabies. It is a more severe form of scabies with a hyperinfestation of lots of scabies mites.

This means that there are thousands or millions of the mites, causing excessive scaling and flaking of the skin. Because there are so many mites, and because the skin is flaking off, scabies can be spread to others extremely easily. The rash is crusting and looks a bit like psoriasis. Scabies can spread rapidly under crowded conditions where close body contact is frequent.

Institutions such as nursing homes, extended-care facilities, and prisons are often sites of scabies outbreaks. Images: Sarcoptes scabiei mites in a skin scraping, stained with lactophenol cotton-blue.
