Scabies is a contagious skin infestation caused by the Sarcoptes scabiei mite. The mites burrow into the outer layer of the skin, commonly causing intense itching and a rash made up of small red bumps or fine burrow lines.
The rash often appears between the fingers, around the wrists, waist, underarms or genital area. Itching may be particularly severe at night. Scratching can break the skin and lead to a secondary bacterial infection.
Scabies usually spreads through prolonged, direct skin-to-skin contact. A brief handshake or hug is less likely to transmit it, but close household contact, sharing a bed or intimate contact can allow the mites to pass from one person to another. Symptoms may take several weeks to appear after a first exposure.
Treatment normally involves a prescribed medicated cream or lotion and, in some cases, oral medication. It is important to follow the instructions carefully and complete the full treatment.
Close household and intimate contacts often need to be treated at the same time, even when they do not yet have symptoms. Clothing, towels and bed linen should be handled according to the healthcare professional’s instructions to reduce the chance of reinfestation.
Seek medical advice when scabies is suspected, symptoms persist after treatment, the skin appears infected, or the affected person is very young, elderly, pregnant or immunocompromised.
