Abstract

The objective of this epidemiological study was to determine whether cysticercosis and especially neurocysticercosis is endemic in Soutou village about half a century after the 1962 outbreak. This study was
carried out from September 2009 to February 2010. It involved a questionnaire administration, serology,
treatment, coproscopy and neuro-imaging. Four hundred and three serum samples were collected from the village people, which covered 94% of the village population. By using a parallel combination of the antigen-detection ELISA and the enzyme-linked immunoelectrotransfer blot (EITB) a cysticercosis seroprevalence of 11.9% (95% CI: 8.9–15.4%) was found. Cerebral CT-scans showed that 23.3% (10/43) of the seropositives were affected by neurocysticercosis. Four out of these 43 (9.3%) were tapeworm carriers.
Seropositivity was significantly associated to older age groups (41–60 years old; p = 0.001 and 61–91 years old; p = 0.028) and absence of a household toilet (p = 0.001). It can be concluded that Soutou village is an active focus of Taenia solium cysticercosis about 50 years after the first reported epidemic outbreak.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
