It is caused by\n                      <jats:italic>Schistosoma haematobium<\/jats:italic>\n                      and causes considerable public health problems to schoolchildren. Ethiopia, after mapping the distribution of the disease (2013 to 2015), launched school-based mass deworming program to treat schoolchildren for schistosomiasis and soil-transmitted helminthiasis (STH) across the country since 2015. However, there is no recent information about the prevalence of the disease among schoolchildren in the current study areas. Diagnostic performance of urine filtration method and urinalysis reagent strip is also lacking. Therefore, this study aimed to determine the prevalence of urogenital schistosomiasis in schoolchildren, and to evaluate diagnostic performance of urine filtration and urinalysis reagent strip in Amibara, Kurmuk and Abobo districts, Ethiopia.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec002\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Across-sectional study was conducted involving 1,171 schoolchildren in Abobo, Amibara and Kurmuk districts from October, 2020 to January, 2021. The study participants were selected using random sampling technique. From each study participant, 10 ml urine samples were collected and examined using urine filtration method and urinalysis reagent strip. Data obtained from the survey were entered into Microsoft Excel 2010 and analysed with SPSS version 20.0. Data was summarized using descriptive statistics. Chi-square, bivariate and multivariable logistic regression and Pearson correlation test were used to measure associations between urogenital schistosomiasis, age, sex and haematuria. Odds ratio was used to measure strengths of association between variables. Agreement between urine filtration method and urinalysis reagent strip was determined using Kappa statistics.\n                      <jats:italic>P-<\/jats:italic>\n                      value &lt; 0.05 at 95%\n                      <jats:italic>CI<\/jats:italic>\n                      was considered as statistically significant.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among the 1,171 urine samples from schoolchildren examined by urine filtration method, 143 (12.2%) were\n                      <jats:italic>S<\/jats:italic>\n                      .\n                      <jats:italic>haematobium<\/jats:italic>\n                      egg positive. Out of 143 positive children 126(88.1%) were lightly infected and 17 (11.9%) were heavily infected. Among the total of 1,171 urine samples tested by dipstick, 264(22.5%) were positive for haematuria. Prevalence of urogenital schistosomiasis by both urine filtration and urinalysis reagent strip method was higher in Abobo than Hassoba (Amibara) and Kurmuk (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.001). The number of egg counts (intensity of infections) were significantly correlated with intensity of haematuria (\n                      <jats:italic>r<\/jats:italic>\n                      = 0.6,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.001). Egg-positive children had significantly higher risk of having haematuria compared to\n                      <jats:italic>S<\/jats:italic>\n                      .\n                      <jats:italic>haematobium<\/jats:italic>\n                      egg negative children (OR; 6.96; 95%CI: 4.98, 8.940). Compared to urine filtration method, the sensitivity, specificity, positive predictive value (PPV) and negative predictive values (NPV) of urinalysis reagent strip were 99.3%, 88.1%, 53.8% and 99.8%, respectively. Furthermore, its positive likelihood ratio (PLR) and negative likelihood ratio (NLR) were 8.34 and 0.008, respectively. The accuracy index and diagnostic odds ratio (DOR) of reagent strip were 0.89 and 1054, respectively. The agreement level between urine filtration methods and urinalysis reagent strip for detecting urogenital schistosomiasis was substantial (Kappa = 0.64).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec004\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study showed that urogenital schistosomiasis was prevalent in schoolchildren in Abobo, Hassoba and Kurmuk districts. Urogenital schistosomiasis prevalence in Hassoba-bure and Kurmuk falls under low category whereas moderate in Abobo and is almost four times compared to Kurmuk and Hassoba-bure. Chemotherapy is needed in schoolchildren in such endemic areas and other measures like access to safe water, improved sanitation, hygiene, and health education should be implemented to control and prevent schistosomiasis effectively. The sensitivity, specificity, positive and negative predictive values of urinalysis reagent strip were higher and could serve as alternative for mass screening of urogenital schistosomiasis, for surveillance and evaluation of schistosomiasis intervention programs.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1371\/journal.pone.0271569","type":"journal-article","created":{"date-parts":[[2022,7,25]],"date-time":"2022-07-25T13:36:04Z","timestamp":1658756164000},"page":"e0271569","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":25,"title":["Urogenital schistosomiasis prevalence and diagnostic performance of urine filtration and urinalysis reagent strip in schoolchildren, Ethiopia"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4258-0782","authenticated-orcid":true,"given":"Ketema","family":"Deribew","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Delenasaw","family":"Yewhalaw","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Berhanu","family":"Erko","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zeleke","family":"Mekonnen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2022,7,25]]},"reference":[{"issue":"2","key":"pone.0271569.ref001","doi-asserted-by":"crossref","first-page":"95","DOI":"10.1016\/j.actatropica.2009.11.012","article-title":"Parasites and poverty: the case of schistosomiasis","volume":"113","author":"CH King","year":"2010","journal-title":"Acta Trop"},{"issue":"10","key":"pone.0271569.ref002","doi-asserted-by":"crossref","first-page":"787","DOI":"10.1016\/j.trstmh.2005.04.013","article-title":"Control of population and schistosomiasis transmission in Ethiopia using the soap berry endod (Phytolacca dodecandra), with special emphasis on application methods","volume":"99","author":"F Abebe","year":"2005","journal-title":"Trans R Soc Trop Med Hyg"},{"key":"pone.0271569.ref003","volume-title":"Schistosomiasis; Progress report 2001\u20132011 and Strategic plan, 2012\u20132020","author":"World Health organization","year":"2013"},{"issue":"1","key":"pone.0271569.ref004","first-page":"41","volume":"77","author":"L Chitsulo","year":"2000","journal-title":"The global status of schistosomiasis and its control.ActaTrop"},{"key":"pone.0271569.ref005","volume-title":"Schistosomiasis fact sheet 115","author":"World Health Organization","year":"2014"},{"issue":"9541","key":"pone.0271569.ref006","doi-asserted-by":"crossref","first-page":"1106","DOI":"10.1016\/S0140-6736(06)69440-3","article-title":"Human schistosomiasis","volume":"368","author":"B Gryseels","year":"2006","journal-title":"Lancet"},{"issue":"5","key":"pone.0271569.ref007","doi-asserted-by":"crossref","first-page":"425","DOI":"10.1016\/j.jare.2012.07.003","article-title":"Epidemiology of schistosomiasis in Egypt: travel through time","volume":"4","author":"RMR Barakat","year":"2013","journal-title":"J Adv Res"},{"issue":"2","key":"pone.0271569.ref008","doi-asserted-by":"crossref","first-page":"383","DOI":"10.1016\/j.idc.2012.03.004","volume":"26","author":"Gryseels B.
