What is scabies?

Scabies spreads very easily from person to person. It can affect anyone. It spreads more easily in crowded living situations or between close contacts.
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 bumps and itching.
How does it spread?
Scabies mites spread from person to person by close contact. They can easily spread between people who live together, sleep in the same bed, or have sex. Sometimes 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.

How is scabies treated?
Scabies won't go away on its own. To get rid of it, and to keep from spreading it to others, you need to use medicine. You might use a special cream that your doctor prescribes. Or your doctor may have you take pills.
Be sure to read and follow all instructions that come with your medicine. A second treatment may be needed 1 to 2 weeks after the first treatment. Most creams or lotions are applied to the entire body. With infants and young children, apply the cream or lotion to the head and neck too.
Children can usually return to daycare or school the day after the first treatment is completed.
Some scabies medicines aren't safe for infants younger than 2 months, children, older adults, and people 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.
After treatment, the itching usually lasts another 2 to 4 weeks. If you still have symptoms after 4 weeks, you may need another treatment.
