A total of 341 stool samples provided by 2- to 15-year-old children were examined using a concentration technique and a Kato\u2013Katz slide. Intensity of infection was expressed as eggs per gram (epg) of feces to classify light, moderate, or heavy intensity infection. A finger-prick blood sample was obtained from each student in the field. Soil-transmitted helminth prevalence was 54.3%, with <jats:italic>Trichuris trichiura<\/jats:italic> as the most prevalent species (48.9%). The combination <jats:italic>T. trichiura<\/jats:italic>\/<jats:italic>Ascaris lumbricoides<\/jats:italic> (12.6%) was the most common. When <jats:italic>T. trichiura<\/jats:italic> or <jats:italic>A. lumbricoides<\/jats:italic> appeared as a single infection, light or moderate intensity infections were seen, whereas when multiple species were identified, heavy infections were present. Anemia was detected in those with any kind of STH infection (42.7%), with statistically significant differences (<jats:italic>P<\/jats:italic> = 0.004) when compared with uninfected individuals (28.2%). Polyparasite infection with one parasite species at moderate intensity and the other parasite species at light intensity or absent was found to be a significant factor for the odds of being anemic (odds ratio = 2.07). The present study reveals a high level of STH transmission requiring a deworming control program in Corn Islands and pointing to the need of improving the education and sanitary conditions of the population to avoid environmental contamination and reinfection.<\/jats:p>","DOI":"10.4269\/ajtmh.18-0195","type":"journal-article","created":{"date-parts":[[2018,10,9]],"date-time":"2018-10-09T07:10:45Z","timestamp":1539069045000},"page":"1591-1597","source":"Crossref","is-referenced-by-count":13,"title":["Soil-Transmitted
