To our knowledge, there is a lack of reports on the prevalence and risk factors of fish-borne zoonotic trematodiasis (FZTi) in humans in many regions of Vietnam.
A cross-sectional study was performed in three communes located in the Red River Delta, northern Vietnam, where residents are reported to have a habit of eating raw freshwater fish, between June 2020 and December 2021. A total of 591 individuals were interviewed using structured questionnaires, and their stool samples were collected for the analysis of fishborne zoonotic trematode (FZT) egg presence using direct microscopic observation and the formalin-ether concentration method. Univariate and multivariable logistic regression analyses were employed to explore potential risk factors.
The prevalence of fish-borne zoonotic trematodiasis (FZTi) was 14.89% among the 591 participants, ranging from 1.52% to 39%. The average age of the participants was 48.31 ± 16.77 years (range: 7-86 years old), and the highest prevalence of FZT infection (17.36%) was observed in individuals aged 19-39 years, followed by those aged 40-59 (16.67%). The prevalence of FZT infectionwas higher in men (17.75%) than in women (11.07%). Factors independently associated with FZTi, obtained by multivariate analysis, included a history of eating raw freshwater fish and the study commune.
The present study has revealed a wide-ranging prevalence of FZTi among humans in Vietnam's Red River Delta. Sustained surveillance efforts for FZTi, as well as the implementation of long-term, practical control policies, and strategies for eliminating FZT in Vietnam, are still necessary.
据我们所知，越南许多地区缺乏关于人类食源性人畜共患吸虫病（FZTi）患病率及危险因素的报告。
2020年6月至2021年12月期间，在越南北部红河三角洲的三个公社开展了一项横断面研究，据报告当地居民有食用生淡水鱼的习惯。使用结构化问卷对591人进行了访谈，并采集他们的粪便样本，采用直接显微镜观察法和福尔马林 - 乙醚浓缩法分析食源性人畜共患吸虫（FZT）虫卵的存在情况。采用单因素和多因素逻辑回归分析来探究潜在危险因素。
591名参与者中食源性人畜共患吸虫病（FZTi）的患病率为14.89%，范围在1.52%至39%之间。参与者的平均年龄为48.31±16.77岁（范围：7 - 86岁），19 - 39岁个体中FZT感染患病率最高（17.36%），其次是40 - 59岁人群（16.67%）。男性FZT感染患病率（17.75%）高于女性（11.07%）。多因素分析得出的与FZTi独立相关的因素包括食用生淡水鱼的历史和研究公社。
本研究揭示了越南红河三角洲地区人类中FZTi的广泛流行情况。对FZTi进行持续监测，以及在越南实施长期、切实可行的控制政策和消除FZT的策略仍然是必要的。
