Scabies is a highly contagious skin infestation caused by the microscopic mite Sarcoptes scabiei var. hominis. These parasites burrow into the skin’s upper layers to lay eggs, triggering intense itching and a characteristic rash. Transmission occurs through prolonged skin-to-skin contact or exposure to contaminated items (clothing, bedding, towels).
Symptoms Include:
Severe itching, often worsening at night.
Red, pimple-like rash or thread-like burrows (tiny grayish-white lines) where mites have tunneled.
Common sites: Finger webs, wrists, elbows, armpits, waistline, buttocks, genital area, and under breasts.
Treatment Protocol:
Topical Prescriptions:
Permethrin cream (5%): First-line therapy applied to the entire body from neck down.
Benzyl benzoate lotion or sulfur ointment (for infants/pregnant individuals).
Oral Medication:
Ivermectin tablets for severe cases or when topical treatments fail.
Household Measures:
Simultaneous treatment of all close contacts, even if asymptomatic.
Decontamination: Machine-wash bedding, clothing, and towels in hot water (60°C/140°F) and dry on high heat. Non-washable items should be sealed in plastic for 72 hours.
Prevention Tips:
Avoid direct skin contact with infected individuals until treatment is complete.
Refrain from sharing personal items.
Disinfect surfaces in shared living spaces.
Why Dermatologist-Guided Care Matters:
Scabies can mimic eczema or allergic reactions; accurate diagnosis via skin scraping is essential.
Improper treatment risks secondary bacterial infections (e.g., impetigo) or persistent symptoms.
Post-treatment itching may last 2–4 weeks due to residual allergic response; antihistamines or mild steroids can help.
