Scabies is a condition of very itchy skin caused by tiny mites that burrow into your skin. The itching is caused by an allergic reaction to the mites.
Scabies spreads very easily from person to person. It can affect people of all ages and from all incomes, social levels, and living situations.
With treatment, the scabies mites die and the itching goes away over a period of days to weeks. Without treatment, the mites continue to reproduce under the skin, causing more sores and itching.
spread from person to person by close contact, such as sleeping in the same bed or touching someone's skin. The mites can also be spread by sharing towels, clothing, and other personal items.
Scabies often affects several household members at the same time. You can spread it to another person before you have symptoms.
Scabies has two main symptoms:
Symptoms are more likely to occur:
In babies and small children, itching and skin irritation may also occur on the scalp, neck, and face and on the palms of the hands and soles of the feet.
If you have many scaly, crusted sores, you may have a rare form of scabies called crusted scabies or Norwegian scabies.
If this is the first time you have had scabies, it may be several weeks before you have itching and skin sores. But if you have had it before, symptoms will probably start in a few days.
Usually a doctor can diagnose scabies based on your symptoms. Scabies is especially likely if you have had close contact with other people who have had the same symptoms.
Sometimes you may have a test to confirm that you have scabies. For example, the doctor may gently scrape some dry skin from an affected area and look at it under a microscope for signs of mites.
Scabies won't go away on its own. To get rid of it, and to keep from spreading it to others, it is usually treated with a non-prescription cream or lotion. These products contain permethrin or another medicine.
Most creams or lotions are applied to the entire body from the neck down. In most cases, you leave the medicine on for 8 to 14 hours and then wash it off. Be sure to read and follow all instructions that come with your medicine.
Children can usually return to daycare or school after treatment is completed.
Some scabies medicines aren't safe for children, older adults, and women who are pregnant or breastfeeding. To avoid dangerous side effects, be sure to follow your doctor's instructions carefully.
If you have scabies, you and anyone you have close contact with must all be treated at the same time. This keeps the mites from being passed back and forth from person to person. Until scabies has cleared up, you should avoid close contact with anyone and make sure not to share any personal items.
To make sure that all the mites are killed:
After treatment, the itching usually lasts another 2 to 4 weeks. It will take your body that long to get over the allergic reaction caused by the mites. Antihistamines include a non-drowsy one like loratadine (Claritin) or one that might make you sleepy like diphenhydramine (Benadryl). Other medicine, like steroid creams, or, in severe cases, steroid pills can help relieve itching. Before you use these medicines, talk with your doctor about what is best for you (or your child).
If you still have symptoms after 4 weeks, you may need another treatment.
