Tuberculosis prevalence survey in the Daveyton (Benoni) urban black community.
A sample of urban Blacks from Daveyton, Tvl, randomly selected to fully represent the parent community, was investigated for bacteriological prevalence of chest abnormalities associated with tuberculosis among adults, as well as for hypersensitivity to tuberculin in children. Radiological evidence of tuberculous lesions was demonstrated in 4.8% of subjects, half of whom were regarded as active cases. In the light of a bacteriological prevalence of 0.7% the radiological prevalence may be an overestimate, particularly since the 1978 incidence rate according to notification figures tends to support the prevalence survey estimates.
