RESUMO
INTRODUCTION: Poliovirus, an enterovirus, still persists in Nigeria despite the global efforts tailored towards its eradication. This study aimed to assess the impacts of poliovirus and other enteroviruses on the susceptibility of individuals to intestinal parasite infections. METHODOLOGY: A cross-sectional study on the prevalence of intestinal parasites was conducted on two-sample stool specimens of 717 Nigerian children (between 1 and 19 years of age) whose poliovirus/other enteroviruses infection status had been determined. RESULTS: The overall prevalence of Sabin poliovirus and other related enteroviruses infections were 6.6% and 13.8%, respectively. The prevalence of Ascaris lumbricoides was significantly higher than that of other intestinal parasites (p < 0.05), with children in the 0-4 year age group being the most predisposed age group to intestinal parasitic infection (OR = 11.7, CI = 9.2-15.0). While the prevalence of all species of parasites except S. mansoni showed no significant variations in children with Sabin poliovirus (p > 0.05), the prevalence of hookworms and Taenia spp. was significantly higher in children with other enteroviral infections (p < 0.05). CONCLUSIONS: The high risk of children of acquiring enteroviral infection through some intestinal parasites is an indication of possible association of the parasites in a more poliovirus-endemic population. A combined intervention approach for the two infections is advocated.
