Scabies – Quick reference for GPs (including OOH)
Key points: Contagious mite infestation causing intense nocturnal pruritus. Look for small erythematous papules, burrows and excoriations at classic sites. Spread is mainly via prolonged skin-to-skin contact. Prompt diagnosis and treatment relieve symptoms, prevent secondary infection and limit community transmission.
What it is
-
Human-specific mite (Sarcoptes scabiei var. hominis) burrows into the epidermis to lay eggs.
-
The host develops a delayed hypersensitivity reaction, driving the itch.
Clinical features
-
Symptoms: Intense pruritus, worse at night.
-
Signs: Small erythematous papules, burrows and excoriations.
-
Typical distribution: Interdigital spaces, wrists, axillae, waistline and genital areas.
Transmission and settings
-
Primarily via prolonged skin-to-skin contact.
-
Outbreaks occur in households, care homes, childcare centres and other close-contact environments.
Why early action matters
-
Symptom relief for the patient.
