Abstract

Background: Arboviruses are an emerging threat of significant impact on human health and well-being. With increasing proportion of the world living in urban environments, inadvertently, there is the creation of better habitats for vector species.
Methodology: Ninety-three plasma samples were collected from subjects in the age range of 1–75 years and screened for Immunoglobulin (IgM) to dengue fever virus (DENV), West Nile virus (WNV), and yellow fever virus (YFV) using the third generation enzyme linked immunosorbent assay.
Results: An overall prevalence of 52.7% (49/93) was recorded from the recruited individuals. IgM antibodies to DENV, YFV, and WNV were found in 16/49 (17.2%), 16/49 (17.2%), and 17/49 (18.3%), respectively. High prevalence was recorded in the age groups 16–30, 31–45, and 61–75 years. Gender analysis of the positive samples showed higher prevalence among females than males. The result also showed high prevalence in urban settings than rural settings for DENV and WNV, however, for YFV, higher prevalence was found in the rural area. The prevalence of dual and trio arboviral infection showed 17.2% and 11.8%, respectively.
Conclusions: This study confirms the circulation of DENV, YFV, and WNV in Ogbomoso and therefore, suggests the need for public awareness on vector control.
