What is Scabies?

Scabies is an itchy skin condition caused by a tiny burrowing mite called Sarcoptes scabiei. The intense itching occurs where the mites burrow under the skin and is often worse at night.

Scabies is highly contagious and spreads quickly through close person-to-person contact. Outbreaks commonly occur within households, child care centers, schools, nursing homes, and prisons. Because it spreads so easily, healthcare providers often recommend treating the entire family or anyone in close contact with an infected person.

Scabies can be effectively treated with medicated creams or pills that kill both the mites and their eggs. However, itching may continue for weeks after treatment due to the body’s allergic reaction.

Symptoms of Scabies

Typical signs and symptoms include:

• Severe itching, often worse at night

• Thin, irregular burrow tracks made of tiny blisters or bumps

Common Sites in Adults and Older Children

• Between fingers and toes

• In the armpits

• Around the waist

• On the wrists and inner elbows

• On the soles of the feet

• Around the nipples or belly button

• On the chest, buttocks, or genitals

Common Sites in Infants and Young Children

• Fingers

• Face, scalp, and neck

• Palms of the hands

• Soles of the feet

If someone has had scabies before, symptoms may begin within days of exposure. For first-time infections, symptoms may take up to six weeks to appear. Importantly, scabies can spread even before symptoms develop.

When to See a Doctor

Consult a healthcare provider if you notice severe itching or a rash. Other skin conditions, like eczema or dermatitis, may look similar but require different treatment. While lotions or antihistamines may reduce itching, they will not kill the mites.

Causes of Scabies

Scabies is caused by female mites that burrow under the skin to lay eggs. After hatching, the larvae travel to the skin’s surface, mature, and spread to other areas or individuals.

The body’s allergic reaction to mites, their eggs, and their waste triggers intense itching. Scabies spreads mainly through prolonged skin-to-skin contact but can also spread through shared clothing, towels, or bedding.

Important Notes

• Pets do not transmit human scabies.

• Animal mites may cause temporary itching but die within days and do not require treatment.

Complications of Scabies

• Skin Infections: Excessive scratching may lead to bacterial infections like impetigo.

• Crusted Scabies: A severe form seen in infants, elderly individuals, or people with weakened immune systems. It causes thick, crusted, scaly skin and can harbor millions of mites. Crusted scabies is extremely contagious and requires urgent treatment with both oral medication and topical creams.

Prevention of Scabies

To prevent reinfection and protect others:

• Wash Clothing and Bedding: Use hot, soapy water to wash clothes, towels, and bedding used within the last three days before treatment. Dry them on high heat.

• Seal Unwashable Items: Place items in sealed plastic bags for at least one week to starve mites.

• Clean and Vacuum: Vacuum carpets, furniture, and floors to remove mites and skin scales, especially in cases of crusted scabies.

Conclusion

Scabies is a contagious but treatable skin condition. Early recognition, proper treatment, and thorough cleaning of personal items and surroundings are essential to stop the spread and prevent reinfection.
