Abstract:
A total of 108 pigs from an endemic area in Mozambique were selected and followed for 8 months to estimate the prevalence and incidence of Taenia solium cysticercosis as indicators of ongoing transmission of the disease. The pigs were sampled and tested repeatedly for cysticercosis by Ag-ELISA at 4, 9 and 12 months of age. Porcine cysticercosis was diagnosed in 5.6% (95% CI: 2.1–11.7%), 33.3% (95% CI: 23.7–44.1%) and 66.7% (95% CI: 55.5–76.9%) of the animals, for the first, second and third sampling rounds, respectively, and varied by village. The mean incidence rate of the disease increased significantly from 6.2 cases per 100 pig-months between 4 and 9 months of age, to 21.2 cases per 100 pig-months between 9 and 12 months of age (incidence rate difference=15.0; 95% CI: 6.8–23.3). Risk factors for the disease are present in the study area, thus control and educational programmes for the community should be initiated to build awareness of the transmission and impact of T. solium infections.
