1. A bilharziasis survey based on the examination of a single-urine specimen of school children was carried out in the northern environs of the Witwatersrand. 2. European and Bantu boys and girls between the ages of 10-16 years showed the highest incidence rate. 3. Considering only those schools which are situated near the Klein Jukskei River, European children in the 10-16 age group show an infection rate of 10% and Bantu children 20%. 4. Physopsis snails from the Klein Jukskei were found to be vectors of B. haematobium under experimental conditions. 5. The area is known to be heavily infected with B. bovis, yet only one human infection was revealed by the survey. It is concluded that human beings are not readily susceptible to bovis infections.
