The purpose of this study is to determine how demographic and exposure factors related to giardiasis vary between travel and endemic cases. Exposure and demographic data were gathered by public health inspectors from giardiasis cases reported from the Region of Waterloo from 2006 to 2012. Logistic regression models were fit to assess differences in exposure to risk factors for giardiasis between international travel-related cases and Canadian acquired cases while controlling for age and sex. Multinomial regression models were also fit to assess the differences in risk profiles between international and domestic travel-related cases and endemic cases. Travel-related cases (both international and domestic) were more likely to go camping or kayaking, and consume untreated water compared to endemic cases. Domestic travel-related cases were more likely to visit a petting zoo or farm compared to endemic cases, and were more likely to swim in freshwater compared to endemic cases and international travel-related cases. International travellers were more likely to swim in an ocean compared to both domestic travel-related and endemic cases. These findings demonstrate that travel-related and endemic cases have different risk exposure profiles which should be considered for appropriately targeting health promotion campaigns.
本研究的目的是确定与贾第虫病相关的人口统计学和暴露因素在旅行相关病例和地方性病例之间如何变化。公共卫生检查员收集了2006年至2012年滑铁卢地区报告的贾第虫病病例的暴露和人口统计学数据。拟合逻辑回归模型以评估在控制年龄和性别的同时，国际旅行相关病例和加拿大本土获得性病例之间贾第虫病危险因素暴露的差异。还拟合了多项回归模型以评估国际和国内旅行相关病例与地方性病例之间风险概况的差异。与地方性病例相比，旅行相关病例（包括国际和国内）更有可能去露营或划皮划艇，以及饮用未经处理的水。与地方性病例相比，国内旅行相关病例更有可能参观宠物动物园或农场，并且与地方性病例和国际旅行相关病例相比，更有可能在淡水中游泳。与国内旅行相关病例和地方性病例相比，国际旅行者更有可能在海洋中游泳。这些发现表明，旅行相关病例和地方性病例具有不同的风险暴露概况，在适当开展健康促进活动时应予以考虑。
