This study was carried out to provide some evidence for the interruption of transmission of lymphatic filariasis (LF) among schoolchildren in Trinidad and Tobago. A cross-sectional survey for LF antigenaemia was performed among 63 (13.2%) of the 479 primary schools located in eight administrative (and geographical) regions of Trinidad and Tobago. From these communities, 2597 schoolchildren aged 6-12 years were sequentially selected for a survey of bancroftian antigenaemia. From each child, 100 microl (finger-prick) whole blood sample was applied to a Binax immunochromatographic card test (ICT), and read for the presence of antigenaemia. The ICT results showed a negative finding for LF antigenaemia and suggest that LF transmission has been interrupted in the survey areas.
