A quasi-experimental study aimed to identify environmental and behavioral risk factors for infection and to evaluate the effectiveness of a community-based intervention program. The intervention program study was conducted over 10 months and comprised three phases: baseline survey\u201a health education intervention program implementation\u201a and follow-up evaluation. The results were analyzed for the prevalence of parasitic infections, and multivariable logistic regression was performed to identify associated factors. The majority of study participants were female (67.94%)\u201a aged 55 to 64 years (48.09%)\u201a and farmers (89.31%). Parasitic infections\u201a especially O. viverrini\u201a substantially decreased during the follow-up period\u201a and independent risk factors predicting infection included lower education\u201a previous infection\u201a raw fish consumption\u201a and pesticide use\u201a according to multivariable logistic regression analysis. This intervention considerably improved knowledge; mean knowledge score increased by 6.29 points (p &lt; 0.001). Analysis of fecal sludge after treatment with the sand-drying system identified S. stercoralis larvae (20 eggs\/L) and Taenia spp. eggs (12.4 eggs\/g). These findings indicated that, despite treatment, integrated behavioral and environmental interventions can be effective in interrupting parasite transmission in rural endemic settings.<\/jats:p>","DOI":"10.3390\/ijerph23050553","type":"journal-article","created":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T09:46:11Z","timestamp":1777455971000},"page":"553","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Impact of Community-Based Health Education and Sanitation Interventions on Opisthorchis viverrini Infection in an Endemic Area of Northeastern Thailand"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7175-2937","authenticated-orcid":false,"given":"Parichart","family":"Boueroy","sequence":"first","affiliation":[{"name":"Faculty of Public Health, Kasetsart University, Chalermphrakiat Sakon Nakhon Province Campus, Sakon Nakhon 47000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nattamol","family":"Phetburom","sequence":"additional","affiliation":[{"name":"Faculty of Public Health, Kasetsart University, Chalermphrakiat Sakon Nakhon Province Campus, Sakon Nakhon 47000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-1584-0578","authenticated-orcid":false,"given":"Birabongse","family":"Hardthakwong","sequence":"additional","affiliation":[{"name":"Faculty of Public Health, Kasetsart University, Chalermphrakiat Sakon Nakhon Province Campus, Sakon Nakhon 47000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3939-8867","authenticated-orcid":false,"given":"Ratanee","family":"Kammoolkon","sequence":"additional","affiliation":[{"name":"Faculty of Public Health, Kasetsart University, Chalermphrakiat Sakon Nakhon Province Campus, Sakon Nakhon 47000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Panchamapohn","family":"Rattanahon","sequence":"additional","affiliation":[{"name":"Faculty of Public Health, Kasetsart University, Chalermphrakiat Sakon Nakhon Province Campus, Sakon Nakhon 47000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5010-4682","authenticated-orcid":false,"given":"Peechanika","family":"Chopjitt","sequence":"additional","affiliation":[{"name":"Faculty of Public Health, Kasetsart University, Chalermphrakiat Sakon Nakhon Province Campus, Sakon Nakhon 47000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5299-8720","authenticated-orcid":false,"given":"Narita","family":"Fakkaew","sequence":"additional","affiliation":[{"name":"Faculty of Public Health, Kasetsart University, Chalermphrakiat Sakon Nakhon Province Campus, Sakon Nakhon 47000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-0082-6649","authenticated-orcid":false,"given":"Pathanan","family":"Suwannaboon","sequence":"additional","affiliation":[{"name":"Faculty of Public Health, Kasetsart University, Chalermphrakiat Sakon Nakhon Province Campus, Sakon Nakhon 47000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8705-3668","authenticated-orcid":false,"given":"Chavanakorn","family":"Krueakaew","sequence":"additional","affiliation":[{"name":"Faculty of Public Health, Kasetsart University, Chalermphrakiat Sakon Nakhon Province Campus, Sakon Nakhon 47000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-0120-410X","authenticated-orcid":false,"given":"Patiwat","family":"Yasaka","sequence":"additional","affiliation":[{"name":"Faculty of Management Technology, Rajamangala University of Technology Isan, Surin Campus, Surin 32000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janjira","family":"Hantakhu","sequence":"additional","affiliation":[{"name":"Ban Huai Lua Subdistrict Health Promoting Hospital, Huai Lua Subdistrict, Ban Muang District, Sakon Nakhon 47140, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6114-6554","authenticated-orcid":false,"given":"Kulthida Y.","family":"Kopolrat","sequence":"additional","affiliation":[{"name":"Faculty of Public Health, Kasetsart University, Chalermphrakiat Sakon Nakhon Province Campus, Sakon Nakhon 47000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Hotez, P.J., Bottazzi, M.E., Strych, U., Chang, L.Y., Lim, Y.A., Goodenow, M.M., and AbuBakar, S.
