摘要
导读：弯曲杆菌病被认为是世界范围内引起人类肠胃炎的最常见的细菌，食物是感染的主要来源之一。然而，人类弯曲杆菌病的发生可能因地理区域和其他因素而有所不同。我们的研究旨在确定葡萄牙北部地区弯曲杆菌感染的可能来源。方法：对2015 - 2017年通过葡萄牙流行病学监测系统（SINAVE）通报的所有实验室确诊弯曲杆菌病病例进行横断面研究。我们分析了社会人口统计学和暴露变量，包括与其他病人的接触、与动物的接触、食用可疑食品、饮用不受控制的水和旅行。结果：2015年至2017年，葡萄牙北部地区共报告了683例弯曲杆菌病确诊病例，通报率为每10万人6.3例。中位年龄为2岁（IQR 0.96-4.6）；58.3%为男性。与动物密切接触是最常见的接触（50.2%），其次是饮用不受控制的水（26.1%）、食用可疑食物（13.8%）和接触病人（8.8%）。与北部其他地区相比，来自 mega e Sousa次区域的弯曲杆菌病病例（46.0%对26.1%）更频繁地暴露于不受控制的水。结论：2015-2017年葡萄牙北部地区报告的弯曲菌病病例疑似主要来源为动物接触和接触不受控制的水源。在 mega e Sousa分区域，主要是接触不受控制的水，这是一个社会经济贫困的地区，人均获得公共供水的机会较低。减少人类弯曲杆菌病负担的预防和控制干预措施应与当地利益攸关方按照“同一个健康”方针实施。
Suspected Sources of Infection and Transmission Factors Associated With Campylobacteriosis in Northern Portugal.
Introduction: Campylobacteriosis is considered the most common bacterial cause of human gastroenteritis worldwide, with food being one of the main sources of infection. The occurrence of human campylobacteriosis, however, may differ between geographical areas and other factors. Our study aims to identify possible sources of Campylobacter infection in the Northern region of Portugal.
Methods: A cross-sectional study was conducted, including all laboratory-confirmed campylobacteriosis cases notified through the Portuguese epidemiological surveillance system (SINAVE) between 2015 and 2017. We analysed socio-demographic and exposure variables, including contact with other ill individuals, contact with animals, consumption of suspect food items, consumption of non-controlled water and travelling.
Results: A total of 683 confirmed campylobacteriosis cases were reported between 2015 and 2017 in the Northern region of Portugal, corresponding to a notification rate of 6.3 per 100,000 population. The median age was 2 years old (IQR 0.96-4.6); 58.3% were male. Close contact with animals was the most common exposure (50.2%), followed by consumption of non-controlled water (26.1%), suspect food consumption (13.8%) and contact with ill individuals (8.8%). Campylobacteriosis cases from the Tâmega e Sousa subregion were more frequently exposed to non-controlled water (46.0% vs. 26.1%) than in the rest of the Northern region.
Conclusion: Contact with animals and exposure to non-controlled water were the main suspected sources of the campylobacteriosis cases notified in Northern Portugal in 2015-2017. Exposure to non-controlled water was predominant in the Tâmega e Sousa subregion, a socio-economically deprived area with lower access to public supply water per capita. Prevention and control interventions to reduce the burden of human campylobacteriosis should be implemented following a One Health approach with local stakeholders.
期刊介绍：
Zoonoses and Public Health brings together veterinary and human health researchers and policy-makers by providing a venue for publishing integrated and global approaches to zoonoses and public health. The Editors will consider papers that focus on timely collaborative and multi-disciplinary research in zoonoses and public health. This journal provides rapid publication of original papers, reviews, and potential discussion papers embracing this collaborative spirit. Papers should advance the scientific knowledge of the sources, transmission, prevention and control of zoonoses and be authored by scientists with expertise in areas such as microbiology, virology, parasitology and epidemiology. Articles that incorporate recent data into new methods, applications, or approaches (e.g. statistical modeling) which enhance public health are strongly encouraged.
