Scabies is a condition that has affected people for centuries, often referred to as “lice of the flesh.” This highly contagious skin disease is caused by microscopic mites that burrow into the skin, causing severe itching and irritation. Despite common misconceptions, scabies can affect anyone, regardless of cleanliness or personal hygiene. In this article, we’ll explore everything you need to know about scabies, from its causes and symptoms to diagnosis and treatment, so you can stay informed and seek the right care.
What is Scabies?
Scabies is a skin condition caused by tiny parasites called Sarcoptes scabiei mites. These mites burrow into the top layer of the skin, creating tunnels where they lay eggs. This results in intense itching and red rashes, especially in areas where the skin folds, such as between the fingers, wrists, and toes.
Imagine small creatures beneath your skin causing irritation — that’s how scabies feels. The condition is widespread, affecting millions globally each year, and it can persist for weeks or months if left untreated.
Causes of Scabies
Scabies is caused by the transfer of mites from person to person through prolonged skin-to-skin contact. This makes environments like crowded hostels, schools, or care homes high-risk. While less common, sharing towels or bedding can also spread the mites.
Myth-Busting About Scabies:
- Cleanliness is not a factor: Scabies does not discriminate based on hygiene or living conditions.
- Pets cannot spread human scabies: The mites that affect humans differ from those found on animals.
Symptoms of Scabies
Symptoms of scabies usually appear 2–5 weeks after infestation. Key symptoms include:
- Intense itching, which worsens at night.
- Red, raised bumps resembling pimples.
- Irritation in areas such as:
- Between the fingers and toes
- Wrists and elbows
- Around the genitals
- In skin creases like knees and elbows
The itching and rash occur because the body reacts to the mites, their eggs, and waste products. If untreated, the mites can spread to other parts of the body, worsening the condition over time.
How Scabies Spreads
The scabies mites are most commonly transferred through:
- Prolonged physical contact: Holding hands, hugging, or living in close quarters.
- Crowded environments: Places like schools or shared accommodations.
- Occasional contact: Though rare, shared bedding or towels may facilitate transmission.
Fascinating Fact: After mating on the skin, the male mite dies while the female burrows into the skin, laying 2–3 eggs daily during her lifespan of 4–8 weeks. These eggs hatch into baby mites, and within 3 weeks, they mature into adults, perpetuating the infestation.
Diagnosing Scabies
Diagnosing scabies can be challenging because its symptoms often mimic other skin conditions like eczema or allergies. Doctors look for the following:
- Classic burrows: Tiny, raised lines in the skin, especially in folds or creases.
- Night-time itching: A telltale sign that distinguishes scabies from other rashes.
- Red bumps: These are common around areas like the hands, wrists, and feet.
In uncertain cases, a dermatologist might:
- Perform a skin scraping to examine under a microscope for mites.
- Conduct additional tests to confirm the diagnosis.
How to Treat Scabies
Treating scabies is straightforward but requires careful adherence to instructions to eliminate the mites entirely.
Primary Treatment:
- Permethrin Cream: This is the first-line treatment, applied from the neck down.
- Leave it on for 8–14 hours, typically overnight.
- Reapply to any areas washed during the treatment period.
- A second application is needed after a week to kill newly hatched mites.
Additional Treatments:
- Oral Medication: For severe infestations, doctors may prescribe oral ivermectin.
- Antihistamines or topical steroids: To manage itching and irritation.
- Antibiotics: If scratching leads to secondary bacterial infections.
Preventing Reinfestation
Scabies treatment should extend to:
- Close contacts: Family members or anyone who has had prolonged physical interaction.
- Bedding and clothing: Wash in hot water above 50°C and dry on high heat.
Note: If symptoms persist after one month of treatment, consult your doctor. There may be additional infections or other underlying skin conditions that require attention.
