Serodetection of West Nile Virus among febrile non malarial patients at Wad Madeni Teaching Hospital

Abstract

The main aim of this study was to se rodetect of west Nile Virus (WNV) among febrile patients at Wad Madeni Teaching Hospital . The present study was carried out during the period from July 2013 to September 2014. Ninety one febrile patients attended to Wad Madeni Teaching Hospital were enrolled in this study.23(25.3%) were males while 68(74.7%) were females. The ages of the patients ranged from 11-78 years. Personal and clinical data were collected by questionnaire after a verbal consent, serum samples were collected, tested for WNV IgG and IgM using Enzyme-Linked immunosorbent assay (ELISA). Thirty two (35.2%) were positive for anti-WNV IgG while 12(13.2%) were positive for anti-WNV IgM. Based on gender 23(25.3%) were males while 68(74.7%) were females. 2 males (2.2%) and 10 female (11%) were anti-WNV IgM positive. Out of 32 IgG positive it was found that 5 males (5.5%) and 27 female (29.7%) were anti-WNV IgM positive . As for patients residence, 55(60.4%) were localized in rural area while 36(39.6%) were localized in urban area. The age, residence and distribution among males and females were not significant(p > 0.05) risk factor to induce WNV IgG and IgM seropositivity. While the contact with birds were found significantly (p < 0.05).
