Assessment of Nonzoonotic Soil-Transmitted Helminth Levels in Soils in Yenagoa Metropolis, Niger Delta
In order to assess the prevalence of nonzoonotic soil-transmitted helminths in the Yenagoa Metropolis, 480 soil samples were collected from five communities for 12 months. The soil samples were collected along two transects from the waterfront and community playgrounds. Analysis was by standard methods. The results obtained from the study described in this article showed that 44.79% (95% confidence interval [CI] = 40.34%–49.24%) of the soil samples tested positive for nonzoonotic soil-transmitted helminths. Ascaris lumbricoides was the most common helminth with a prevalence rate of 35% (95% CI = 30.73%–39.27%). Mixed occurrence of nonzoonotic soil-transmitted helminths was 10.21%. Although the community playgrounds had a higher prevalence of nonzoonotic soil-transmitted helminths than the waterfront (p > .05), more cases of mixed occurrence of nonzoonotic soil-transmitted helminths occurred in the waterfront than the community playgrounds (p > .05). The wet season had a higher prevalence rate of nonzoonotic soil-transmitted helminths than the dry season (p < .05). The observed high prevalence of nonzoonotic soil-transmitted helminths in soil is considered a potential public health risk to swimmers and children playing outdoors in the Yenagoa metropolis.
