This community based survey was undertaken to assess the prevalence, characteristics and risk factors of diarrhoea in children < 5 years of age in an urban zone, at Kinshasa, Zaire. 155 community cases selected by cluster sampling, 155 age-matched controls, and 18 children with diarrhoea seen at a health centre (HC) were examined. The diarrhoea prevalence rate was 6.

Clinical algorithms for the screening of women for gonococcal and chlamydial infection: evaluation of pregnant women and prostitutes in Zaire.

A substantial proportion of women with gonococcal and/or chlamydial infection are asymptomatic. Thus active case detection is problematical, particularly in developing countries, where facilities and materials for laboratory testing are limited. We assessed the diagnostic validity of the hierarchical clinical algorithms recommended by the World Health Organization as well as that of a nonhierarchical scoring system, using data for 1,160 pregnant women (a low-prevalence group) and 1,222 prostitutes (a high-prevalence group) in Kinshasa, Zaire.
