Opisthorchis viverrini infection is a serious public health problem in Southeast Asia especially in the northeast and north of Thailand. Therefore, a cross-sectional survey using multistage sampling was conducted from the rural communities of Surin province, Thailand, during September 2013 to July 2014. O. viverrini infection was determined using Kato's thick smear technique. Socio-demographic, information resources, and history data were collected using predesigned semi-structured questionnaires. A total of 510 participants completed interviews and had stools collected. Some 32 (6.47%) participants were infected with O. viverrini. The rate was slightly higher in males (6.61%) than females (6.32%). High frequencies were found in the age groups 61-70 (19.4%) and 71-80 years (19.4%), those involved in agriculture (10.5%), and in primary school (10.3%). The distribution of high infection was found in Tha Tum (16.7%) and Sankha district (16.7%), followed by Samrong Thap (13.3%), Si Narong (13.33%), and Buachet district (13.33%). Chi-square testing indicated that age (61-70 and 71-80 year old), education (primary school) and occupation (agriculture), were significantly associated with O. viverrini infection (p-value<0.05). Of 72.6% participants who had past histories with stool examination, 17.0% of them had been infected with O. viverrini and 43.2% treated with praziquantel. This finding confirmed that O. viverrini is still a problem in Surin province, Thailand, and therefore, interventions are urgently required for mass treatment and health education implementation.
猫后睾吸虫感染是东南亚尤其是泰国东北部和北部严重的公共卫生问题。因此，于2013年9月至2014年7月期间在泰国素林府的农村社区采用多阶段抽样进行了一项横断面调查。使用加藤厚涂片技术确定猫后睾吸虫感染情况。通过预先设计的半结构化问卷收集社会人口统计学、信息资源和病史数据。共有510名参与者完成访谈并采集了粪便样本。约32名（6.47%）参与者感染了猫后睾吸虫。男性感染率（6.61%）略高于女性（6.32%）。61 - 70岁（19.4%）和71 - 80岁（19.4%）年龄组、从事农业者（10.5%）以及小学文化程度者（10.3%）的感染频率较高。高感染分布见于达图姆县（16.7%）和讪卡县（16.7%），其次是三隆塔县（13.3%）、西纳隆县（13.33%）和布阿切县（13.33%）。卡方检验表明，年龄（61 - 70岁和71 - 80岁）、教育程度（小学）和职业（农业）与猫后睾吸虫感染显著相关（p值<0.05）。在有粪便检查既往史的72.6%参与者中，17.0%曾感染猫后睾吸虫，43.2%接受过吡喹酮治疗。这一发现证实猫后睾吸虫在泰国素林府仍是一个问题，因此迫切需要采取干预措施进行大规模治疗并开展健康教育。
