Scabies
What is it?
Scabies is a skin infestation caused by tiny mites that are smaller than crabs and harder to see. The mites burrow into the skin where they live and reproduce.
What are the symptoms?
The most common symptom is intense itching which is caused by the mites burrowing under the skin to lay eggs. The mites like warm areas of skin, especially the groin and armpits. The itch is often worst at night when in a warm bed and after a hot shower.
How is it transmitted?
Scabies are transmitted from skin to skin contact with an infested person. It can be spread by sexual contact and non sexual contact. It is less commonly passed through sharing clothes or a bed. Scabies usually get noticed within four weeks.
How can I prevent transmission?
It's hard to prevent transmission of scabies as they are easily caught from close body contact. You can prevent further outbreaks by appropriate treating and cleaning of all clothing and linen that may have come into contact with scabies.
How is it diagnosed?
Scabies are detected by examining itchy areas under a bright light. When they burrow they often leave fine red marks on the skin. Because they burrow under the skin, you don't often see the mites.
How is it treated?
Scabies can be rapidly and effectively treated by using an appropriate cream or lotion. Several treatments are available, your doctor or pharmacist will be able to discuss treatment options with you. Follow the treatment instructions carefully.
You will also need to change and wash any clothing and linen which has been in direct contact with the affected areas, and ensure your sexual partner is treated at the same time. Other housemates need to consider treatment if they have slept in the same bed, shared towelling or clothing of the person infected. Treatment is usually repeated in 1-2 weeks. It is common for the itch to persist for several weeks after treatment. Antihistamines and creams may be useful to help relieve itching and prevent scratching.
If not treated itching will continue and sores may become infected, it can also spread to sexual partners and household contacts.
