Scabies is a contagious skin infestation caused by the human itch mite Sarcoptes scabiei, characterized by intense pruritis.
Proper understanding of Scabies is essential for appropriate clinical management and patient outcomes.
Epidemiology and Clinical Significance
Scabies demonstrates distinct epidemiological patterns across different demographic groups and geographic regions.
- Factor 1: Sarcoptes scabiei hominis mite infestation
- Factor 2: Transmission through prolonged skin-to-skin contact
- Factor 3: Fomite transmission rare; mites die within 3-4 days off skin
- Factor 4: Increased risk with crowding, poor hygiene, immunosuppression
Causes and Risk Factors
Scabies develops through dysregulation of normal skin homeostatic mechanisms.
- Intense pruritis, often worse at night
- Burrows (linear, thread-like tracts) on hands, wrists, elbows
- Papules, vesicles, and excoriations
- Common sites: interdigital spaces, flexural areas, genitals
- Secondary bacterial infection from scratching possible
Pathophysiology and Disease Mechanisms
Understanding the molecular and cellular mechanisms underlying Scabies guides precision therapeutics.
- Permethrin 5% cream (gold standard) - apply full body, repeat in 1 week
- Ivermectin oral (especially for crusted/Norwegian scabies)
- Alternative topicals: sulfur ointment, crotamiton
- Treat all household members and close contacts
- Wash all linens and clothing in hot water
