The aim of this study was to identify factors associated with <jats:italic>Schistosoma mansoni<\/jats:italic> infestation. A cross-sectional study was performed to assess factors associated with <jats:italic>S. mansoni<\/jats:italic> endemicity in a municipality in Northeast Brazil with a history of reporting schistosomiasis. Participants were divided into four groups: 1) new <jats:italic>S. mansoni<\/jats:italic> cases (<jats:italic>n<\/jats:italic> = 44), 2) past history of <jats:italic>S. mansoni<\/jats:italic> treatment (<jats:italic>n<\/jats:italic> = 78), 3) immediate neighbors (<jats:italic>n<\/jats:italic> = 158), and 4) nearby controls (<jats:italic>n<\/jats:italic> = 35). Multiple comparisons analysis was performed. Subjects had a mean of 6.6 \u00b1 3.9 years of education, and no difference was observed regarding family income (one-way analysis of variance, <jats:italic>P<\/jats:italic> = 0.215). A total of 95.9% of the individuals had rudimentary cesspit as sanitary wastewater. The mean body mass index was 28.3 \u00b1 5.1, with 41.0% and 24.1% overweight and obesity, respectively. Of note, 28.9% of adults had hypertension. Hemoglobin, mean corpuscular volume, and mean corpuscular hemoglobin were higher in the recent <jats:italic>S. mansoni<\/jats:italic> treated group (Wilks\u2019 lambda, <jats:italic>P<\/jats:italic> &lt; 0.001). Male gender was more prevalent in new <jats:italic>S. mansoni<\/jats:italic> cases (likelihood ratio, <jats:italic>P<\/jats:italic> &lt; 0.001), close proximity to water collections was a risk for <jats:italic>S. mansoni<\/jats:italic> infestation (likelihood ratio, <jats:italic>P<\/jats:italic> &lt; 0.001), and a better hematological status was observed in individuals recently treated with praziquantel. This study indicates the need to maintain surveillance for <jats:italic>S. mansoni<\/jats:italic> in low-transmission areas and the need to establish community-based interventions to control transmission.<\/jats:p>","DOI":"10.4269\/ajtmh.19-0513","type":"journal-article","created":{"date-parts":[[2021,2,16]],"date-time":"2021-02-16T19:52:02Z","timestamp":1613505122000},"page":"1404-1411","source":"Crossref","is-referenced-by-count":2,"title":["Factors Associated with Schistosoma mansoni Infestation in Northeast Brazil: A Need to Revisit Individual and Community Risk Factors"],"prefix":"10.4269","volume":"104","author":[{"given":"Danielle V.
