We investigated the epidemic and conducted a case\u2013control study in the village of Limon. Blood samples were obtained for cases and controls. Patients with obvious sequelae underwent cerebrospinal fluid (CSF) sampling as well. We used enzyme\u2010linked immunosorbent assay (ELISA) and neutralization tests for laboratory diagnosis and identified 31 cases with encephalitis, four of whom died. Median age was 36\u2003months. Bivariate analysis did not reveal any significant association with the risk factors investigated. Laboratory analysis confirmed presence of IgM antibodies caused by WNV in eight of 13 cases, indicative of recent viral infection. The unique aspects of the WNW outbreak in Sudan, i.e. disease occurrence solely among children and the clinical domination of encephalitis, involving severe neurological sequelae, demonstrate the continuing evolution of WNV virulence. The spread of such a virus to other countries or continents cannot be excluded.<\/jats:p>","DOI":"10.1111\/j.1365-3156.2004.01253.x","type":"journal-article","created":{"date-parts":[[2004,12,29]],"date-time":"2004-12-29T18:54:30Z","timestamp":1104346470000},"page":"730-736","source":"Crossref","is-referenced-by-count":44,"title":["Outbreak of West Nile virus causing severe neurological involvement in children, Nuba Mountains, Sudan, 2002"],"prefix":"10.1111","volume":"9","author":[{"given":"Evelyn","family":"Depoortere","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justine","family":"Kavle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kees","family":"Keus","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Herv\u00e9","family":"Zeller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9verine","family":"Murri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominique","family":"Legros","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,6,8]]},"reference":[{"key":"e_1_2_15_2_1","first-page":"845","article-title":"Outbreak of West Nile\u2010like viral encephalitis.
