Scabies sexually transmitted infection What is scabies? Without effective treatment, the life cycle of the scabies mite can continue indefinitely. Scabies mites are resistant to soap and hot water and can't be scrubbed out of the skin. Scabies mites can't fly or jump, which means they can only move from one human body to another if 2 people have direct and prolonged physical contact.

It's unlikely that scabies will be transmitted through brief physical contact, such as shaking hands or hugging. Scabies mites can survive outside the human body for 24 to 36 hours, making infection by coming into contact with contaminated clothes, towels or bed linen a possibility. However, it's rare for someone to be infected in this way. Scabies infestations can spread quickly because people are usually unaware they have the condition until 2 to 3 weeks after the initial infection.

There's an increased risk of catching scabies in confined environments, such as schools and nursing homes, where people are in close proximity to one another. Your GP should be able to diagnose scabies from the appearance of your skin, and by looking for the burrow marks of the Sarcoptes scabiei mite.

However, as scabies is spread very easily, it's often possible to make a confident diagnosis if more than one family member has the same symptoms. Your GP will also want to rule out other skin conditions that may be causing your symptoms, such as eczema or impetigo a highly contagious bacterial skin infection.

The burrows of scabies mites can be identified by using an ink test. Ink is rubbed around an area of itchy skin before being wiped off with an alcohol pad. If scabies burrows are present, some of the ink will remain and will have tracked into the burrows, showing up as a dark line. To confirm the diagnosis, a skin sample may be gently scraped from the affected area so it can be examined under a microscope for evidence of scabies mites, their eggs and faeces poo.

If you think you have genital scabies or your partner has been diagnosed with it, visit your nearest sexual health clinic , where you'll be examined and, if necessary, treated. If you decide to treat scabies yourself, you'll need to have a full sexual health check to make sure you don't have any sexually transmitted infections STIs. To prevent reinfection, it's important that all members of your household are treated, as well as any sexual partners you've had over the last 6 weeks in the case of genital scabies.

If you've had genital scabies in the past, anyone you've had sex with in the previous 48 hours will need to be treated. If you're embarrassed about contacting previous sexual partners, your GP surgery or local sexual health clinic may be able to inform them that they've been exposed to scabies on your behalf without disclosing your identity.

Some sexual health clinics operate on a walk-in basis. Others work by appointment only. It's therefore a good idea to call first. When you attend a clinic, you'll be asked for your name, date of birth and contact details. These details will be treated confidentially and won't be passed on to your GP without your agreement.

See your GP immediately if you have scabies and you haven't had a previous infection. Delaying treatment places other people at risk. As other more serious skin conditions can sometimes cause similar symptoms to the symptoms of scabies , your GP will need to rule these out. If you have scabies, your partner will also need to be treated regardless of whether or not they have any symptoms.

This is because it's highly likely that scabies will have been transmitted through close bodily contact, such as during sex. To reduce the risk of reinfection, avoid having sex and other forms of prolonged close bodily contact, such as holding hands, until both you and your partner have completed the full course of treatment. If you've been diagnosed with scabies, you may be advised to visit your nearest sexual health clinic to be checked and, if necessary, treated for other sexually transmitted infections STIs.

Lotions and creams are commonly used to treat scabies. Your GP, pharmacist or nurse will be able to advise you about which treatment to use. To prevent reinfection, all members of your household and any close contacts, including recent sexual partners see diagnosing scabies for further details , should be treated at the same time as you, even if they don't have any symptoms.

The cream or lotion should be applied to the skin of all of your body, except your head. Before you apply it, make sure your skin is cool and dry. Don't apply it after having a hot bath. If you apply it when your body is hot, it will quickly be absorbed into your skin and won't remain on the area where the scabies burrows are. Contact your GP if the itching hasn't improved after 2 weeks of treatment and you notice new burrows on your skin.

It can take a month after treatment for the general itching to subside completely, and longer for the lumpy genital lesions to resolve. Your GP may recommend repeating the treatment or they may prescribe a different lotion. On the day you first apply the cream or lotion, you should wash all bed linen, nightwear and towels at a temperature above 50C F.

If you're unable to wash certain items, place them in a plastic bag for at least 72 hours. After this time, the scabies mites will have died. In cases of crusted scabies, you should clean the floors in your house and thoroughly vacuum your carpets and furniture, including the armchairs and sofa. If you've been diagnosed with scabies, avoid close and prolonged physical contact with others until you've applied the cream or lotion. Introduction to scabies: A child has an itchy rash.
