Resumo: From September through December 2005, an outbreak of hemorrhagic fever occurred in South Kordofan, Sudan. Initial laboratory test results identified IgM antibodies against yellow fever (YF) virus in patient samples, - a YF outbreak was declared on 14 November. To control the outbreak, a YF mass vaccination campaign was conducted - vector control implemented in parts of South Kordofan. Surveillance data were obtained from the Sudan Federal Ministry of Health. Clinical information - serum samples were obtained from a subset of patients with illness during the outbreak. Nomads, health personnel - village chiefs were interviewed about the outbreak. Mosquitoes were collected in 11 villages - towns in North - South Kordofan. From 10 September to 9 December 2005 a total of 605 cases of outbreak-related illness were reported, of which 45% were in nomads. Twenty-nine percent of 177 patients seen at clinics in Julud - Abu Jubaiyah had illness consistent with YF. Five of 18 unvaccinated persons with recent illness - 4 of 16 unvaccinated asymptomatic persons had IgM antibodies to YF virus. IgM antibodies to chikungunya virus were detected in five (27%) ill persons - three (19%) asymptomatic persons. These results indicate that both chikungunya - YF occurred during the outbreak.
