Abstract

Scabies is a parasitic infestation of the skin caused by the mite Sarcoptes scabiei var. hominis. It is common in tropical areas, including the sub-tropical areas of Southern Africa. Predisposing factors are overcrowding, poor personal hygiene, low socio-economic standards and impaired host immunity. Although it can occur at any age, scabies is commonly seen in children and young adults. It is not a fatal disease; however, it can cause severe morbidity and poor quality of life. Scabies can complicate with pyoderma which may result in post-streptococcal glomerulonephritis. There are two clinical variants, classic scabies and the much rarer crusted scabies (Norwegian scabies).
