Scabies

Scabies is an itchy skin condition caused by a tiny burrowing mite called Sarcoptes scabiei. Intense itching occurs in the area where the mite burrows. The urge to scratch may be especially strong at night.

Scabies is contagious and can spread quickly through close physical contact in a family, child care group, school class, nursing home or prison. Because scabies is so contagious, doctors often recommend treatment for entire families or contact groups.<

Scabies can be readily treated. Medications applied to your skin kill the mites that cause scabies and their eggs. But you may still have some itching for several weeks after treatment.

Symptoms

Scabies signs and symptoms include:

  • Itching, often severe and usually worse at night
  • Thin, irregular burrow tracks made up of tiny blisters or bumps on your skin

The burrows or tracks typically appear in folds of skin. Though almost any part of the body may be involved, in adults and older children scabies is most often found:

  • Between the fingers
  • In the armpits
  • Around the waist
  • Along the insides of the wrists
  • On the inner elbows
  • On the soles of the feet
  • Around the breasts
  • Around the male genital area
  • On the buttocks
  • On the knees

In infants and young children, common sites of infestation usually include the:

  • Scalp
  • Palms of the hands
  • Soles of the feet

If you’ve had scabies before, signs and symptoms may develop within a few days of exposure. If you’ve never had scabies, it can take as long as six weeks for signs and symptoms to begin. You can still spread scabies even if you don’t have any signs or symptoms yet.

When to see a doctor

Talk to your doctor if you have signs and symptoms that may indicate scabies.

Many skin conditions, such as dermatitis or eczema, are associated with itching and small bumps on the skin. Your doctor can help determine the exact cause and ensure that you receive proper treatment. Bathing and over-the-counter preparations may ease itching, but they won’t eliminate scabies.
