Scabies

Contagious skin infestation caused by a mite, Sarcoptes scabiei. Its occurrence is closely related to a lack of water and poor hygiene.

Clinical picture

- Nocturnal itching, scratch marks, burrows between the fingers
(made visible by applying ink, then washing it off), and papules.

- Secondary infection (from scratching) resembles impetigo.

- Whole family is often infested.

- Often localised to: genital region, axillae, chest, breasts, hands and thighs.

Treatment (dispensary)

- Wash the whole body with a mild soap and dry, then apply 25 % benzyl benzoate emulsion (BBE) to the whole body except head and neck. Use a broad paint brush if available. Allow to dry, then put on the same clothes.

- Repeat for 3 days.

- If a secondary bacterial infection occurs, treat as for impetigo for 4 to 5 days. Only apply benzyl benzoate emulsion once all lesions are closed (is very irritant).

- Treat the whole family. After the treatment, boil and air all clothes and bedding.

- Warn patients that itching may persist for several weeks. This represents an allergic reaction to the dead mites, not treatment failure.
