title: The presence of Schistosoma mansoni in Montserrat Leeward Islands.
abstract: Following the discovery in two villages in Montserrat of five individuals who were passing Schistosoma mansoni ova in their stools, a house to house survey was undertaken in November 1978 to determine the prevalence of the infection. From 158 persons residing in the two villages 137 faecal samples were received. Of these 14% were positive for S. mansoni ova. The enzyme linked immunosorbent assay (ELISA) was performed on finger-prick blood samples collected on chromatography paper. In the ELISA 16% of the 132 persons tested were positive. In comparison with the stool examination, the ELISA showed a 53% sensitivity and a 92% specificity. It was recommended that the individuals passing schistosome eggs should be treated.
