It spreads very fast in crowded areas when close body contact is frequent as well as during personal contacts Scabies occurs more often in developing countries and tropical climates. Besides, it is one of the most widespread skin diseases in children. However, nowadays dermatologists can easily diagnose and successfully treat scabies.

What is Scabies?

Scabies is an infestation, not an infection. Tiny mites reproduce on the skin surface, burrow in the outer layers of the skin and plant eggs in there. This skin condition is characterized by intense itching and skin rash. The mite is often spread during skin-to-skin contact with a person who is already infested with scabies.

The skin rash looks typical for some other diseases too, so scabies may be easily confused with other conditions in its early stages. For example, acne and mosquito bites can look like scabies. What sets the latter apart is severe itching. Each year millions of people contract scabies all over the world. The young people and the old are two groups, commonly affected by scabies.

What causes scabies?

Scabies is caused by the infestation with the female mite called Sarcoptes scabiei. The parasites dig into the upper layers of the skin known as the epidermis and deposit their tiny eggs in there. After three or four days, the larvae hatch and reach the skin surface, where they grow and mature into adults.

Scabies mites can be present at any area of the body, but their favorite places include warm spots between fingers, around breast creases and the buttock, under fingernails, around the navel and waistline or within skin folds. They also hide under bracelets, rings or watch straps.

Most people only carry 10 to 15 insects at a given time. Moreover, each mite is not more than half a millimeter long which makes them difficult to spot. However, a microscope can easily identify scabies mites and eggs from a skin scraping.

How is it contracted?

Scabies mites cannot fly or jump, they crawl slowly instead, so the only way for them to move from one person to another is wait for the people to have extended physical contact. Holding hands can transmit scabies but typically it is not spread through a hug or a quick handshake.

The disease can be quickly passed between sexual partners or household members. Shared personal items may be to blame if they are contaminated. Scabies parasites can survive outside the body for 24 to 36 hours.

Scabies can be contracted through wearing clothes or sleeping in bedding that is infested. There’s an elevated risk of contracting scabies in confined environment. Such institutions as extended-care facilities, nursing homes and prisons are common sites of scabies outbreaks. Moreover, child care facilities are typical sites of infestations.

Incubation Period

After a person has been infested for the first time, symptoms may show up in around 4–6 weeks. The symptoms develop more quickly in those people who have already had scabies before.

If it’s a recurrence, symptoms appear in 1–4 days after the exposure. Once infested, a person is contagious and can pass scabies to other people even if he or she has not developed any symptoms yet. This is called the incubation period.

Symptoms of Scabies

The hallmark symptoms of scabies include intense itching and an itchy rash. They may affect large areas or be limited to armpits, breasts, wrists, thighs, elbows, penis, webbing between fingers, belt-line, buttocks, nipples and waist.

Sometimes the rash can consist of scales and tiny blisters. Scratching the rash may result in skin sores; these sores can be infected by bacteria. Tiny burrows can be seen on the skin because the female scabies mite make tunnels just beneath the skin surface.

However, mites are usually few in number (10–15 parasites per person) that’s why these burrows are difficult to identify. These crooked skin-colored or grayish-white lines are best seen in the webbing between fingers, on the penis and breast, in the folds of the skin on the wrist, knee or elbow. People infested with crusted scabies, however, may not show usual signs of the disease such as rash or itching.


If you have suspicions concerning the presence of scabies in your body, don’t be afraid or embarrassed to visit a dermatologist. In most cases, the disease can be identified based on the appearance of rash, tiny mite burrows and your description of intense itching.

A health care professional will also perform different tests on the skin surface. A skin scraping may be necessary to identify the problem and name the precise diagnosis.

This procedure is composed of collecting small skin samples from the affected area and examining them for mites, fecal matter or eggs. A person can still be contaminated even if no signs can be found as not more than 10–15 mites are typically present on the whole body. However, people with crusted scabies can have thousands of parasites, becoming highly contagious.

Symptoms may include oozing honey-colored blisters. It is recommended to treat skin infections with prescribed medications. Moreover, scabies are also known to worsen some pre-existing conditions of the skin, including eczema.
