A survey of the prevalence of bancroftian filariasis was conducted in August-September 1992 in the northern part of the Kassena-Nankana District, Upper East Region, Ghana. 200 compounds from 3 different communities were randomly selected from the vitamin A trial database. All resident compound members were examined for clinical manifestations of lymphatic filariasis and capillary blood was obtained between 21:00 and 01:00 and examined using the counting chamber technique. 1603 people were examined, 741 males and 862 females. The overall prevalence of microfilaraemia was 32.4% (95% confidence interval 30.1-34.7). Geometric mean microfilaria density (infected persons only) was 794 per mL. The most important clinical manifestation was hydrocele (in 32% of males) followed by limb elephantiasis (in 3.6% of the study population). There was no significant difference between the 3 communities in clinical or parasitological findings.
