Scabies is a common and highly contagious skin infestation caused by a microscopic mite called Sarcoptes scabiei. The mite burrows into the top layer of the skin, where it lives and lays eggs. This triggers an allergic reaction in the body, leading to intense itching and a visible skin rash. Scabies can affect people of all ages and occurs worldwide.
Scabies symptoms include:
Scabies is caused by a microscopic mite and spreads easily through close contact. Knowing the causes helps prevent infection and control its spread.
Scabies is usually diagnosed based on clinical signs and, in some cases, simple tests to confirm the presence of mites.
Certain factors increase the likelihood of getting scabies, especially in close-contact settings.
Scabies is treatable with prescription medications that kill the mites and help relieve symptoms. Treatment should include the affected person and close contacts.
Topical Permethrin Cream: Applied over the entire body, this cream kills the mites and their eggs. It is considered the first-line treatment and is safe for most people, including children and adults.
Oral Ivermectin: Used in severe cases, crusted scabies, or when topical treatment fails. It is taken as a pill and helps control outbreaks or infestations in people who cannot use creams.
Antihistamines: These medications reduce itching and allergic reactions caused by the mites. They are especially helpful at night when itching is worst.
Topical Corticosteroids: Mild steroid creams may be applied after mite treatment to reduce inflammation, redness, and swelling caused by the immune response to the infestation.
Antibiotics: Prescribed only if secondary bacterial infections develop from scratching. They help prevent complications and promote skin healing.
Treatment of Close Contacts: All household members and close contacts should be treated at the same time, even if they show no symptoms, to prevent reinfestation and break the cycle of transmission.
