International travel is thought to be a major risk factor for developing gastrointestinal (GI) illness for UK residents. Here, we present an analysis of routine laboratory and exposure surveillance data from North East (NE) England, describing the destination-specific contribution that international travel makes to the regional burden of GI infection.Laboratory reports of common notifiable enteric infections were linked to exposure data for cases reported between 1 January 2013 and 31 December 2022. Demographic characteristics of cases were described, and rates per 100,000 visits were determined using published estimates of overseas visits from the Office for National Statistics (ONS) International Passenger Survey (IPS).About 34.9% of cases reported international travel during their incubation period between 2013 and 2022, although travel-associated cases were significantly reduced (>80%) during the COVID-19 pandemic. Between 2013 and 2019, half of and non-typhoidal infections and a third of , , and Shiga toxin-producing (STEC) infections were reported following travel. Rates of illness were highest in travellers returning from Africa and Asia (107.8 and 61.1 per 100,000 visits), with high rates also associated with tourist resorts like Turkey, Egypt, and the Dominican Republic (386.4-147.9 per 100,000 visits).International travel is a major risk factor for the development of GI infections. High rates of illness were reported following travel to both destinations, which are typically regarded as high-risk and common tourist resorts. This work highlights the need to better understand risks while travelling to support the implementation of guidance and control measures to reduce the burden of illness in returning travellers.
国际旅行被认为是英国居民患胃肠道（GI）疾病的一个主要危险因素。在这里，我们分析了英格兰东北部（NE）的常规实验室和暴露监测数据，描述了国际旅行对该地区 GI 感染负担的特定目的地贡献。2013 年 1 月 1 日至 2022 年 12 月 31 日期间报告的病例的实验室报告与暴露数据相关联。描述了病例的人口统计学特征，并使用国家统计局（ONS）国际乘客调查（IPS）公布的海外访问估计数，确定了每 10 万次访问的发病率。在 2013 年至 2022 年期间的潜伏期内，报告有国际旅行的病例约占 34.9%，尽管在 COVID-19 大流行期间，与旅行相关的病例显著减少（>80%）。在 2013 年至 2019 年期间，一半的 和非伤寒 感染以及三分之一的 、 和产志贺毒素大肠埃希菌（STEC）感染是在旅行后报告的。从非洲和亚洲返回的旅行者的发病率最高（每 10 万次访问 107.8 和 61.1 例），与土耳其、埃及和多米尼加共和国等旅游胜地相关的发病率也很高（每 10 万次访问 386.4-147.9 例）。国际旅行是 GI 感染发展的一个主要危险因素。在旅行后报告了大量的疾病，这些目的地通常被认为是高风险和常见的旅游胜地。这项工作强调了在旅行时需要更好地了解风险，以支持实施指导和控制措施，减少返回旅行者的疾病负担。
