HEALTH TIP

• Scabies is an itchy, highly contagious skin disease caused by an infestation by the itch mite Sarcoptes scabiei.
• Direct skin-to-skin contact is the mode of transmission.
• A severe and relentless itch is the predominant symptom of scabies.
• Sexual contact is the most common form of transmission among sexually active young people, and scabies has been considered by many to be a sexually transmitted disease (STD), although not all cases are transmitted sexually.
• Signs and symptoms of scabies include a skin rash composed of small red bumps and blisters that affects specific areas of the body. Other symptoms can include tiny red burrows on the skin and relentless itching. The itchy skin leads to frequent scratching, which may predispose the skin to secondary infections.
• Treatment includes oral or topical scabicidal drugs.
• Over-the-counter remedies or home remedies are not effective in eliminating scabies

 Scabies is an itchy, highly contagious skin disease caused by an infestation by the itch mite Sarcoptes scabiei. Mites are small eight-legged parasites (in contrast to insects, which have six legs). They are tiny, just 1/3 millimeter long, and burrow into the skin to produce intense itching, which tends to be worse at night. The mites that infest humans are female and are 0.3 mm-0.4 mm long; the males are about half this size. Scabies mites can be seen with a magnifying glass or microscope. The scabies mites crawl but are unable to fly or jump. They are immobile at temperatures below 20 C, although they may survive for prolonged periods at these temperatures.


Curing scabies is rather easy with the administration of prescription scabicide drugs. There are no approved over-the-counter preparations that have been proved to be effective in eliminating scabies, and home remedies are not effective. The following steps should be included in the treatment of scabies:

1. Apply a mite-killer like permethrin (Elimite). These creams are applied from the neck down, left on overnight, then washed off. This application is usually repeated in seven days. Permethrin is approved for use in people 2 months of age and older and is considered to be the safest and most effective treatment for scabies.
2. An alternative treatment is 1 ounce of a 1% lotion or 30 grams of cream of lindane, applied from the neck down and washed off after approximately eight hours. Since lindane can cause seizures when it is absorbed through the skin, it should not be used if skin is significantly irritated or wet, such as with extensive skin disease, rash, or after a bath. As an additional precaution, lindane should not be used in pregnant or nursing women, the elderly, people with skin sores at the site of the application, children younger than 2 years of age, or people who weigh less than 110 pounds. Lindane is not a first-line treatment and is only recommended if patients cannot tolerate other therapies or if other therapies have not been effective. Resistance to this medication has also been frequently reported.
