Visiting friends and relatives (VFRs), especially young VFRs, are increasingly recognized in the industrialized world as a high-risk group of travelers.
We performed a descriptive, cross-sectional design study of cases of malaria, hepatitis A, and typhoid reported to the Quebec registry of notifiable diseases between January 2004 and December 2007, occurring in VFRs and non-VFRs travelers.
VFRs account for 52.9% of malaria cases, 56.9% of hepatitis A cases, and 94.4% of typhoid cases reported in Quebec travelers. Almost all (91.6%) of the malaria cases among VFRs were acquired in Africa, particularly in sub-Saharan Africa. An important proportion of malaria cases among VFRs (86.4%) were due to Plasmodium falciparum. The vast majority (76.6%) of typhoid fever cases among VFRs were reported by travelers who had visited the Indian subcontinent. Among VFRs, 40% of total cases were under 20 y of age, compared to less than 6% among non-VFRs. Those under 20 years of age also accounted for 16.9% of malaria cases, 50% of typhoid cases, and 65.2% of hepatitis A cases among VFRs.
Our study clearly shows that VFR children should be a primary target group for pre-travel preventive measures.
在工业化国家,探亲访友旅行者(VFR),尤其是年轻的 VFR,越来越被认为是高风险旅行者群体。
我们对 2004 年 1 月至 2007 年 12 月期间向魁北克传染病报告登记处报告的疟疾病例、甲型肝炎病例和伤寒病例进行了描述性、横断面设计研究,这些病例发生在探亲访友旅行者和非探亲访友旅行者中。
探亲访友旅行者占报告给魁北克旅行者的疟疾病例的 52.9%、甲型肝炎病例的 56.9%和伤寒病例的 94.4%。VFR 中几乎所有(91.6%)的疟疾病例都是在非洲获得的,特别是在撒哈拉以南非洲。VFR 中相当大比例(86.4%)的疟疾病例是由恶性疟原虫引起的。VFR 中大多数(76.6%)伤寒病例是由前往印度次大陆的旅行者报告的。在探亲访友旅行者中,40%的病例年龄在 20 岁以下,而非探亲访友旅行者中不到 6%。20 岁以下的旅行者还占 VFR 中疟疾病例的 16.9%、伤寒病例的 50%和甲型肝炎病例的 65.2%。
我们的研究清楚地表明,VFR 儿童应该是旅行前预防措施的主要目标人群。
