However, current epidemiological data are still lacking for a number of areas, including historical HAT foci. In order to update the HAT situation in the historical focus of forested Guinea, we implemented a geographically based methodology: Identification of Villages at Risk (IVR). The methodology is based on three sequential steps: Desk-based IVR (IVR-D), which selects villages at risk of HAT on the basis of HAT archives and geographical items; Field-based IVR (IVR-F), which consists in collecting additional epidemiological and geographical information in the field in villages at risk; and to be Medically surveyed IVR (IVR-M), a field data analysis through a Geographic Information System (GIS), to compile a list of the villages most at risk of HAT, suitable to guide active screening and passive surveillance. In an area of 2385\u00a0km<jats:sup>2<\/jats:sup> with 1420,530 inhabitants distributed in 1884 settlements, 14 villages with a population of 11,236 inhabitants were identified as most at risk of HAT and selected for active screening. Although no HAT cases could be confirmed, subjects that had come into contact with <jats:italic>Trypanosoma brucei gambiense<\/jats:italic> were identified and two sentinel sites were chosen to implement passive surveillance. IVR, which could be applied to any <jats:italic>gambiense<\/jats:italic> areas where the situation needs to be clarified, could help to reach the objective of HAT elimination.<\/jats:p>","DOI":"10.1051\/parasite\/2019061","type":"journal-article","created":{"date-parts":[[2019,10,10]],"date-time":"2019-10-10T08:01:10Z","timestamp":1570694470000},"page":"61","source":"Crossref","is-referenced-by-count":17,"title":["Sleeping sickness in the historical focus of forested Guinea: update using a geographically based method"],"prefix":"10.1051","volume":"26","author":[{"given":"Fabrice","family":"Courtin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oumou","family":"Camara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mamadou","family":"Camara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mo\u00efse","family":"Kagbadouno","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruno","family":"Bucheton","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Solano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vincent","family":"Jamonneau","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"250","published-online":{"date-parts":[[2019,10,10]]},"reference":[{"key":"R1","doi-asserted-by":"crossref","first-page":"9","DOI":"10.4000\/com.1049","volume":"217","author":"Bidou","year":"2002","journal-title":"Les Cahiers d\u2019Outre-Mer"},{"key":"R2","doi-asserted-by":"crossref","first-page":"828","DOI":"10.1111\/tmi.12316","volume":"19","author":"Camara","year":"2014","journal-title":"Tropical Medicine and International Health"},{"key":"R3","doi-asserted-by":"crossref","first-page":"354","DOI":"10.3201\/eid1602.090967","volume":"16","author":"Chappuis","year":"2010","journal-title":"Emerging Infectious Disease"},{"key":"R4","doi-asserted-by":"crossref","first-page":"334","DOI":"10.1111\/j.1365-3156.2008.02007.x","volume":"13","author":"Courtin","year":"2008","journal-title":"Tropical Medicine and International Health"},{"key":"R5","doi-asserted-by":"crossref","first-page":"256","DOI":"10.1051\/nss\/2011146","volume":"19","author":"Courtin","year":"2011","journal-title":"Natures Sciences Soci\u00e9t\u00e9s"},{"key":"R6","unstructured":"De Raadt P. 2005.
