Scabies: Symptoms, Causes, Treatment & Prevention

Scabies is a highly contagious skin infestation caused by the microscopic mite Sarcoptes scabiei. It leads to intense itching and a characteristic rash, often worse at night. While uncomfortable, scabies is treatable and does not cause long-term damage when addressed promptly. It affects people of all ages and backgrounds, spreading easily in close living situations.

Classic signs include:

• Intense itching, particularly at night
• Pimple-like rash or small red bumps
• Thin, wavy burrows (lines) on the skin
• Common locations: finger webs, wrists, elbows, armpits, waist, genitals, and buttocks
• In infants: palms, soles, and scalp may be affected

Scratching can lead to sores and secondary bacterial infections.

The female mite burrows into the upper layer of skin to lay eggs. It spreads primarily through prolonged skin-to-skin contact. Sharing bedding, clothing, or towels can also transmit it. Crusted (Norwegian) scabies is a more severe form in immunocompromised individuals and is highly contagious.

A dermatologist diagnoses scabies through examination and sometimes skin scraping. Treatment usually involves:

• Topical permethrin cream applied from the neck down
• Oral ivermectin for severe or crusted cases
• Antihistamines or steroids for itching relief
• Washing all bedding, clothing, and towels in hot water

All close contacts should be treated simultaneously, even if asymptomatic. Itching may persist for weeks after mites are killed.

• Avoid close contact with infected individuals
• Do not share personal items
• Wash bedding and clothing after treatment
• Maintain good hygiene in crowded environments

See a dermatologist if you have persistent intense itching or a suspicious rash. Prompt treatment prevents spread to family members.
