Opisthorchis viverrini infection is a serious public-health problem in Southeast Asia. It is associated with a number of hepatobiliary diseases and the evidence strongly indicates that liver fluke infection is the etiology of cholangiocarcinoma.
This study aimed to determine Opisthorchis viverrini infection in elderly people in Surin province, Northeastern Thailand.
A community-based cross-sectional survey was conducted among 333 elderly in 17 districts of Surin province, during one year period from January to December 2011. O. viverrini infection was determined using Kato's Thick Smear technique and socio-demographic were collected using predesigned semi-structured questionnaires, respectively.
A total of 333 elderly including 116 males and 217 females were selected from different study sites. Overall intestinal parasitic infection was 16.2%, predominantly in O. viverrini (9.91%) and followed by Strongyloides stercolaris (4.80%) and hookworm (1.50%), respectively. The O. viverrini infection was found higher in males (13.8%) than females (7.83%), and frequently in elderly 60-70 year old with 14.2%. Chi-square testing indicated that education and occupation were significantly associated with O. viverrini infection (P value = 0.02). The distribution of O. viverrini infection was found in 11 districts which was covered 64.7% of the studies areas. The highest prevalence was found in Thatum with 39.1%, and followed by Sangkha (24.0%), Buachet (21.1%), Samrong Thap (19.1%), Si Narong (15.0%), and Ratanaburi (13.3%) districts.
This findings stress that O viverrini is still a problem in Thailand. We confirmed, for the first time, the high endemicity of human O. viverrini infections in elderly in Surin province of Thailand, underlying the fact that mass treatment and health education are urgently required.
华支睾吸虫感染是东南亚地区一个严重的公共卫生问题。它与多种肝胆疾病相关，且有强有力的证据表明肝吸虫感染是胆管癌的病因。
本研究旨在确定泰国东北部素林府老年人中华支睾吸虫的感染情况。
在2011年1月至12月的一年时间里，对素林府17个区的333名老年人进行了一项基于社区的横断面调查。分别使用加藤厚涂片技术确定华支睾吸虫感染情况，并使用预先设计的半结构化问卷收集社会人口统计学信息。
从不同研究地点共选取了333名老年人，其中男性116名，女性217名。总体肠道寄生虫感染率为16.2%，主要是华支睾吸虫（9.91%），其次是粪类圆线虫（4.80%）和钩虫（1.50%）。男性华支睾吸虫感染率（13.8%）高于女性（7.83%），60 - 70岁老年人感染率最高，为14.2%。卡方检验表明，教育程度和职业与华支睾吸虫感染显著相关（P值 = 0.02）。在11个区发现了华支睾吸虫感染分布，覆盖了64.7%的研究区域。感染率最高的是他通，为39.1%，其次是桑卡（24.0%）、布阿切（21.1%）、三龙塔（19.1%）、西纳荣（15.0%）和叻达布里（13.3%）区。
这些发现强调华支睾吸虫在泰国仍是一个问题。我们首次证实了泰国素林府老年人中华支睾吸虫感染的高流行率，这突出了迫切需要进行大规模治疗和健康教育这一事实。
