Scabies is caused by Sarcoptes scabiei (a mite which lays its eggs under the skin surface). Condoms do not protect you against scabies.
Symptoms include:
Direct skin-to-skin contact with an infected person and oral, anal and vaginal sex.
Your doctor or pharmacist may prescribe anti-scabies lotions. All bed linen, towels and clothing must be washed in hot water and dried well. The itch often lasts for four weeks after successful treatment.
Condoms and dams do not protect you against scabies.
