Abstract
The knowledge on the presence and seroprevalence of arboviruses in Iraq is fragmental. To assess the exposure of the population to arbovirus infections in southern Iraq, we conducted a serological screening of the most common arbovirus groups using immunofluorescence, hemagglutination inhibition and neutralization tests. Serum samples of 399 adult volunteers were collected in Nasiriyah, Iraq. Antibodies were detected against West Nile virus (WNV) (11.6%), sandfly-borne Sicilian virus serocomplex (18.2%), sandfly-borne Naples virus serocomplex (7.8%), Sindbis virus (1.5%), chikungunya virus (0.5%), and Tahyna virus (2.0%). The results suggest that WNV and sandfly-borne phlebovirus infections are common in southern Iraq, and these viruses should be considered as potential causative agents in patients with febrile disease and/or neurological manifestations.
