背景国际旅行与病媒传播疾病，特别是疟疾的风险增加有关。本研究的目的是前瞻性地评估寄生虫病在加拿大旅行者的相对频率，并描述这些感染的人口统计学和旅行相关的预测因素。前瞻性收集了1997年11月至2003年6月期间在多伦多总医院热带病科跨越国际边界的加拿大人和新移民的数据，并输入GeoSentinel监测网络数据库。在数据库中的3，528名返回加拿大的旅行者和新移民中，有1，010人被诊断出寄生虫感染。3，528名旅行者的平均年龄为37.3岁，42.6%为男性。那些被诊断患有寄生虫感染的人比其余的队列更有可能为了移民而旅行（21.1% vs 7.1%，p < 0.001），或者拜访朋友和亲戚（VFR）（17.9% vs 11.8%，p < 0.01）。常见寄生虫感染包括非溶组织阿米巴病（N = 209）、疟疾（N = 143）、皮肤幼虫移行症（N = 105）、贾第鞭毛虫病（N = 74）和血吸虫病（N = 48）。寄生虫感染发生在29%的加拿大旅客。新移民和脆弱家庭成员感染疟疾以及原生动物和蠕虫的风险增加。
Background. International travel is associated with increased risk of vector-borne illnesses, particularly malaria. The objective of this study was to prospectively assess the relative frequency of parasitic diseases in Canadian travelers and to characterize demographic and travel-related predictors of these infections.Methods. Data on Canadians and new immigrants who crossed international borders and were seen in the Tropical Disease Unit of Toronto General Hospital between November 1997 and June 2003 were prospectively collected and entered into the GeoSentinel Surveillance Network database.Results. Of 3,528 returned Canadian travelers and new immigrants in the database, 1,010 had a parasitic infection diagnosed. Mean age of the 3,528 travelers was 37.3 years, and 42.6% were male. Those diagnosed with parasitic infections were more likely than the remaining cohort to have been traveling for the purpose of immigration (21.1% vs 7.1%, p < 0.001), or visiting friends and relatives (VFR) (17.9% vs 11.8%, p < 0.01). Common parasitic infections included nonhistolytica amebiasis (N = 209), malaria (N = 143), cutaneous larva migrans (N = 105), giardiasis (N = 74), and schistosomiasis (N = 48).Conclusions. Parasitic infections occurred in 29% of Canadian travelers. New immigrants and VFRs are at increased risk for malaria, as well as protozoal and helminthic infections.
