Scabies
Cause:
Scabies is a skin infestation caused by small mites that burrow into the skin. The mites make a shallow burrow in the skin to lay their eggs. New insects hatch from the eggs and can be spread to other parts of the skin by scratching.
Symptoms:
The main symptoms of scabies are:
- Intense itching, typically worse at night and after a hot bath or shower
- A bump or blister-like rash, which is often difficult to see.
- Usually there is little rash to see because the mites bury into the skin. The rash will most likely be visible between fingers and on the wrists, armpits, stomach and genitals.
Symptoms usually develop two to four weeks after infection. However, people who have previously been exposed may develop symptoms within 24-48 hours, because the immune system takes less time to respond.
Generally, a person is no longer infectious 24 hours after treatment.
How is it spread?:
Scabies is spread by direct, prolonged physical contact including sexual activity. Scabies mites can survive away from humans for about 24-36 hours, so it is possible to get scabies from infected articles such as bed linen and clothing, although this is much less common.
Treatment:
Treatment involves applying a cream or lotion specifically used for treating scabies, which is available from the pharmacist. Also treat clothing and bedding. Sexual partners and household members also need treatment.
Prevention:
Condoms offer no protection against scabies.
