Scabies in urban Bangladesh.

As a part of a larger project on hygiene education and diarrhoeal diseases we followed 766 children less than 6 years of age from October 1984 to September 1985 in Dhaka, Bangladesh. The aims were to estimate the annual risk of infestation with scabies in children, to describe its involvement of other family members, and to determine some of the familial and individual risk factors for apparent infestation by scabies. During this period 589 (77%) children appeared to have been infected with scabies, and 125 (16%) children were infested for more than 6 months. Of the factors examined, direct and indirect indicators of decreased wealth and incorrect hygiene practices correlated with higher rates of apparent infestation, although scabies rates remained high at all socioeconomic levels.
