Travel-related enteric infections likely represent a large proportion of all enteric infections in British Columbia (BC). The objective of this study was to assess the proportion of enteric infections in BC reported in 2008 associated with international travel in order to understand trends in infections so that targeted interventions can be implemented.
Travel information for all reported cases of salmonellosis, verotoxigenic E. coli (VTEC) infection, shigellosis, Vibrio parahemolyticus infection, botulism, cholera, listeriosis, typhoid fever, paratyphoid fever, hepatitis A infection, cryptosporidiosis, cyclosporiasis and a representative proportion of campylobacteriosis was collected. Temporal, demographic and geographic analysis was conducted comparing locally-acquired infections to infections acquired during international travel. Travel destination was compared between cases of enteric infections and the BC population.
Of the 3,120 enteric infections reported in 2008, 60% were classified as locally-acquired and 40% were associated with international travel. The proportion of infections associated with international travel was highest among 30 to 39 year olds. Locally-acquired infections were highest in the summer months and international travel-related infections were highest in the winter. Asia and Mexico were the most common destinations in relation to enteric infections acquired internationally. The proportion of enteric infections was significantly higher than the proportion of the BC population travelling to these areas.
The proportion of enteric infections in BC associated with international travel is significant. Identification and assessment of locally-acquired infections separately from those associated with international travel will improve assessment of trends and rates for enteric infections in BC and lead to more targeted public health actions.
在不列颠哥伦比亚省（BC），与旅行相关的肠道感染可能占所有肠道感染的很大比例。本研究的目的是评估 2008 年报告的与国际旅行相关的 BC 肠道感染的比例，以便了解感染趋势，从而实施有针对性的干预措施。
收集了所有报告的沙门氏菌病、产肠毒素性大肠杆菌（VTEC）感染、志贺氏菌病、副溶血性弧菌感染、肉毒中毒、霍乱、李斯特菌病、伤寒、副伤寒、甲型肝炎感染、隐孢子虫病、环孢子虫病和代表性比例的弯曲杆菌病的报告病例的旅行信息。对本地获得性感染和国际旅行获得性感染进行了时间、人口统计学和地理分析。对肠道感染病例和 BC 人群的旅行目的地进行了比较。
在 2008 年报告的 3120 例肠道感染中，60%为本地获得性感染，40%与国际旅行有关。30 至 39 岁人群中与国际旅行相关的感染比例最高。本地获得性感染在夏季最高，国际旅行相关感染在冬季最高。亚洲和墨西哥是与国际旅行相关的肠道感染最常见的目的地。肠道感染的比例明显高于前往这些地区的 BC 人口比例。
BC 与国际旅行相关的肠道感染比例很高。将与国际旅行相关的肠道感染与本地获得性感染分别进行识别和评估，将改善对 BC 肠道感染趋势和发病率的评估，并导致更有针对性的公共卫生行动。
