在老挝人民民主共和国，对猫后睾吸虫的详细调查很少。目的是记录O.在一个高流行区的灵猫感染。随机抽样（13个村，每村15户，所有家庭成员年龄> 6个月）。进行临床检查、简短访谈和粪便检查（Kato-Katz技术）。解剖鱼样品以确定是否存在囊蚴。共招募了814人（中位年龄16岁，51.5%为女性）。患病率为58.5%。感染率随年龄增长而增加（20.0~85.5%; P <0.001）。感染的强度和食用未煮熟的鱼的习惯也随着年龄的增长而增加。在研究参与者中，75.2%的人报告烹饪鱼不够。在研究村庄消费的23种不同种类的鲤科鱼类中，有20种被感染。在村一级，生鱼消费的流行与O。灵猫（r = 0.76，P = 0.003）。在个人层面上，年龄，食用未煮熟的鱼，以及缺乏卫生设施有很强的相关性。与O.需要对灵猫感染进行评估，以便制定和实施适当的干预措施。(C)2006年皇家热带医学和卫生学会。由爱思唯尔有限公司出版。保留所有权利。
In Lao PDR, detailed investigations on Opisthorchis viverrini are scarce. The objective was to document epidemiological features of O. viverrini infections in a highly endemic district. A random sample was selected (13 villages, 15 households/village, all household members aged >6 months). Clinical examinations, short interviews and stool examinations (Kato-Katz technique) were performed. Fish samples were dissected for the presence of metacercaria. In total, 814 persons were enrolled (median age 16 years, 51.5% women). The prevalence was 58.5%. Infection rates increased with age (from 20.0 to 85.5%; P< 0.001). Intensity of infection and the habit of consuming insufficiently cooked fish also increased with age. Of the study participants, 75.2% reported cooking fish insufficiently. Of the 23 different species of cyprinoid fish consumed in the study villages, 20 species were infected. At the village level, the prevalence of raw fish consumption was strongly associated with the infection status of O. viverrini (r=0.76, P=0.003). At individual level, age, the consumption of insufficiently cooked fish, and the absence of sanitation were strongly associated. The disease associated with O. viverrini infection needs to be assessed in order to develop and conduct adequate interventions. (C) 2006 Royal Society of Tropical Medicine and Hygiene.
