Scabies Prevention/Scabies is an intensely itchy dermatosis caused by the mite Sarcoptes scabiei. A patient with ordinary scabies may have an average of 12 mites; however, those with crusted scabies may have thousands of mites. The infestation occurs at all ages, but particularly in children. It is a common public health problem in poor communities and is widespread in many underdeveloped countries. Scabies is highly contagious, and person to person spread occurs via direct contact with the skin. Transfer from clothes and bedding occurs rarely and only if contaminated by infested people immediately beforehand.

Scabies is an infestation of the skin by the mite Sarcoptes scabiei. Typical sites of infestation are skin folds and flexor surfaces. In adults, the most common sites are between the fingers and on the wrists, although infection may manifest in older people as a diffuse truncal eruption. In infants and children, the face, scalp, palms, and soles are also often affected. Infection with the scabies mite causes discomfort and intense itching, particularly at night, with irritating papular or vesicular eruptions. The discomfort and itching can be especially debilitating in immunocompromised people, such as those with HIV/AIDS.

Scabies Prevention, Treatment, Complications

Types of Scabies

There’s only one type of mite that causes a scabies infestation. This mite is called Sarcoptes scabiei. However, these mites can cause several types of infestations.

  • Typical scabies – This infestation is the most common. It causes an itchy rash on the hands, wrists, and other common spots. However, it doesn’t infest the scalp or face.
  • Nodular scabies – This type of scabies may develop as itchy, raised bumps or lumps, especially in the genital areas, armpits, or groin.
  • Norwegian scabies – Some people with scabies may develop another form of scabies known as Norwegian scabies, or crusted scabies. This is a more severe and extremely contagious type of scabies. People with crusted scabies develop thick crusts of skin that contain thousands of mites and eggs.

Crusted scabies can also appear

  • thick
  • gray
  • easy to crumble when touched

Crusted scabies usually develops in people with weakened immune systems. This includes people with HIV or AIDS, people who use steroids or certain medications (such as some for pain, swelling, stiffness, or reduced movement. সহজ বাংলা: জয়েন্টের প্রদাহ।" data-rx-term="arthritis" data-rx-definition="Arthritis means joint inflammation causing pain, swelling, stiffness, or reduced movement. সহজ বাংলা: জয়েন্টের প্রদাহ।">arthritis: Rheumatoid arthritis is an autoimmune joint disease causing infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation, pain, and swelling. সহজ বাংলা: রোগপ্রতিরোধ ব্যবস্থার ভুল আক্রমণে জয়েন্টের প্রদাহ।" data-rx-term="rheumatoid arthritis" data-rx-definition="Rheumatoid arthritis is an autoimmune joint disease causing inflammation, pain, and swelling. সহজ বাংলা: রোগপ্রতিরোধ ব্যবস্থার ভুল আক্রমণে জয়েন্টের প্রদাহ।">rheumatoid arthritis), or people who are undergoing chemotherapy.

Causes of Scabies

Scabies Prevention, Treatment, Complications

Scabies is an infestation of the sarcoptes scabiei mite, also known as the human itch mite. After burrowing under the skin, the female mite lays its eggs in the tunnel it has created. Once hatched, the larvae move to the surface of the skin and spread across the body or to another host through close physical contact.

Humans are not the only species affected by mites. Dogs and cats can also be infected. However, each species hosts a different species of mite, and while humans may experience a mild, transient skin reaction to contact with non-human animal mites, a full-blown human infection with animal mites is rare.

Scabies is highly contagious and spread via direct skin-to-skin contact or by using a towel, bedding, or furniture infested with the mites. As such, some of the most likely people to become infested with mites include:

  • Children attending day care or school
  • Parents of young children
  • Sexually active young adults and people with multiple sexual partners
  • Residents of extended care facilities
  • Older adults
  • People who are immunocompromised, including those with HIV/AIDS, transplant recipients, and others on immunosuppressant medications

Symptoms of Scabies

The onset of symptoms of scabies varies depending on whether or not a person has previously been exposed to mites. The first time a person is exposed to the scabies mite, it can take upwards of 2 to 6 weeks[rx] for symptoms to develop. This time frame is significantly shorter in subsequent infestations as the body’s immune system is quicker to react, typically within 1 to 4 days.

Signs and symptoms of scabies include:

  • Itching – This is often worse at night and can be severe and intense. Itching is one of the most common scabies symptoms.
  • RashWhen the mite burrows into the skin, it forms burrow tracks, or lines, which are most commonly found in skin folds, and resemble hives, bites, knots, pimples, or patches of scaly skin. Blisters may also be present.
  • SoresThese occur in infested areas where a person has scratched at the skin. Open sores can lead to impetigo, commonly caused by secondary infection with Staphylococcus aureus.
  • Thick crusts – Crusted scabies, also known as Norwegian scabies, is a form of severe scabies in which hundreds to thousands of mites and mite eggs are harbored within skin crusts, causing severe skin symptoms.

Most often, those affected with crusted scabies exhibit widespread, gray, thick, crumbling crusts.

Mites living in the detached crusts can live for upwards of a week without needing human contact due to the food provided by the crusts themselves.

The most common site of infestation in adults and older children include:

  • in between the fingers
  • around fingernails
  • armpits
  • waistline
  • inner parts of the wrists
  • inner elbow
  • soles of the feet
  • the breasts, particularly the areas around the nipples
  • male genitalia
  • buttocks
  • knees
  • shoulder blades

Infants and young children experience infestation in other areas of the body, including the:

  • scalp
  • face
  • neck
  • palms of the hands
  • soles of the feet

Diagnosis of Scabies

Other ways to make a definitive diagnosis for scabies include:

  • skin scraping (scraping an oil-covered scalpel blade across a burrow and examining the sample microscopically),

  • a burrow ink test (covering a ulcer. সহজ বাংলা: শরীরের অস্বাভাবিক দাগ, ক্ষত বা ফোলা অংশ।" data-rx-term="lesion" data-rx-definition="A lesion is an abnormal area of tissue such as a spot, wound, patch, lump, or ulcer. সহজ বাংলা: শরীরের অস্বাভাবিক দাগ, ক্ষত বা ফোলা অংশ।">lesion with ink and removing it with alcohol leaves ink tracking in the burrows),

  • dermatoscopy (direct visualization of magnified skin). This option is not practical in many locations, especially remote communities.[

We initially allocate 4 points to evidence from RCTs, and 2 points to evidence from observational studies. To attain the final GRADE score for a given comparison, points are deducted or added from this initial score based on preset criteria relating to the categories of quality, directness, consistency, and effect size. Quality: based on issues affecting methodological rigour (e.g., incomplete reporting of results, quasi-randomisation, sparse data [<200 people in the analysis]). Consistency: based on similarity of results across studies. Directness: based on generalisability of population or outcomes. Effect size: based on magnitude of effect as measured by statistics such as relative risk, odds ratio, or hazard ratio.

Scabies Treatment

Products used to kill scabies mites are called scabicides. No “over-the-counter” (non-prescription) products have been tested and approved to treat human scabies.

The following medications for the treatment of scabies are available only by prescription.

Classic scabies: one or more of the following may be used

  • Permethrin cream 5% Brand name product – Elimite Permethrin is approved by the US Food and Drug Administration (FDA) for the treatment of scabies in persons who are at least 2 months of age. Permethrin is a synthetic pyrethroid similar to naturally occurring pyrethrins which are extracts from the chrysanthemum flower. Permethrin is safe and effective when used as directed. Permethrin kills the scabies mite and eggs. Permethrin is the drug of choice for the treatment of scabies. Two (or more) applications, each about a week apart, may be necessary to eliminate all mites. Children aged 2 months or older can be treated with permethrin.
  • Crotamiton lotion 10% and Crotamiton cream 10% Brand name products: Eurax ; Crotan Crotamiton is approved by the US Food and Drug Administration (FDA) for the treatment of scabies in adults; it is considered safe when used as directed. Crotamiton is not FDA-approved for use in children. Frequent treatment failure has been reported with crotamiton.
  • Sulfur (5%-10%) ointment (multiple brand names) Sulfur in an ointment base (petrolatum) is safe for topical use in children, including infants under 2 months of age. The odor and cosmetic quality may make it unpleasant to use.
  • Lindane lotion 1% Brand name products: None availableLindane is an organochloride. Although FDA-approved for the treatment of scabies, lindane is not recommended as a first-line therapy. Overuse, misuse, or accidentally swallowing lindane can be toxic to the brain and other parts of the nervous system; its use should be restricted to patients who have failed treatment with or cannot tolerate other medications that pose less risk. Lindane should not be used to treat premature infants, persons with a seizure disorder, women who are pregnant or breast-feeding, persons who have very irritated skin or sores where the lindane will be applied, infants, children, the elderly, and persons who weigh less than 110 pounds.
  • Ivermectin Brand name product: Stromectol Ivermectin is an oral antiparasitic agent approved for the treatment of worm infestations. Evidence suggests that oral ivermectin may be a safe and effective treatment for scabies; however, ivermectin is not FDA-approved for this use. Oral ivermectin should be considered for patients who have failed treatment with or who cannot tolerate FDA-approved topical medications for the treatment of scabies. If used for classic scabies, two doses of oral ivermectin (200µg/kg/dose) should be taken with food, each approximately one week apart. The safety of ivermectin in children weighing less than 15 kg and in pregnant women has not been established.
    Note that although ivermectin guidelines recommend taking on an empty stomach, scabies experts recommend taking with a meal to increase bioavailability (CITE NEJM Currie article).

Crusted scabies: both oral and topical agents should be used

  • Ivermectin – Brand name product: StromectolIvermectin is an oral antiparasitic agent approved for the treatment of worm infestations. Evidence suggests that oral ivermectin may be a safe and effective treatment for scabies; however, ivermectin is not FDA-approved for this use. The safety of ivermectin in children weighing less than 15 kg and in pregnant women has not been established.
    For crusted scabies, ivermectin should be administered together with a topical agent. Oral ivermectin (200µg/kg/dose) should be taken with food. Depending on infection severity, ivermectin should be taken in three doses (approximately days 1, 2, and 8), five doses (approximately days 1, 2, 8, 9, and 15), or seven doses (approximately days 1, 2, 8, 9, 15, 22, and 29).
  • Permethrin cream 5% – Brand name product: ElimitePermethrin is approved by the US Food and Drug Administration (FDA) for the treatment of scabies in persons who are at least 2 months of age. Permethrin is a synthetic pyrethroid similar to naturally occurring pyrethrins which are extracts from the chrysanthemum flower. Permethrin is safe and effective when used as directed. Permethrin kills the scabies mite and eggs. Permethrin is the drug of choice for the treatment of scabies. Topical permethrin should be administered every 2-3 days for 1-2 weeks to treat crusted scabies.
  • Benzyl benzoate 25% (with or without tea tree oil) – Benzyl benzoate may be used as an alternative topical agent to permethrin. However, this agent may cause immediate skin irritation. Lower concentrations may be used in children (10% or 12.5%).
  • Keratolytic cream – A topical keratolytic cream may also be used to help reduce the crusting of the skin and aid in the absorption of the topical permethrin or benzyl benzoate.

Topical benzyl benzoate versus topical sulfur ointment:

  • We found one systematic review (search date 2010), which identified one RCT (158 adults and children) comparing topical benzyl benzoate with topical sulfur ointment.

Treatment failure

  • Topical benzyl benzoate compared with topical sulfur ointment We don’t know how topical benzyl benzoate and topical sulfur ointment compare at reducing the proportion of people with treatment failure at 15 days (low-quality evidence[Rx].

How can I keep from getting scabies

  • Abstinence (not having sex) is the best form of prevention.
  • Mutual monogamy (having sex with sex with only 1 uninfected partner who only has sex with you) is effective.
  • Limit the number of sexual partners to reduce exposure to all STDs.
  • Use latex condoms for all types of sexual penetration (oral, vaginal, anal). Note: Latex condoms, when used consistently and correctly, can reduce the risk of transmission of other STDs, but are not considered effective against scabies.
  • Know your partner(s). Careful consideration and open communication between partners may protect all partners involved from infection.
  • Have regular check-ups if you are sexually active.
  • If you have an STD, don’t have sex (oral, vaginal, or anal) until all partners have been treated.
  • Prompt, qualified, and appropriate medical intervention and treatment and follow-up are important steps in breaking the disease cycle.

Care roadmap for: Scabies Prevention, Treatment, Complications

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
