随着流行国家的持续移民，寄生虫感染筛查仍然是美国服务难民和移民人口社区的优先事项。我们报告了2001年10月至2004年1月在加州圣克拉拉县难民诊所就诊的533名难民中蠕虫和原虫的患病率以及与这些感染相关的人口统计学危险因素。14%的难民粪便中发现了寄生虫，其中9%发现有一种或多种原生动物，6%发现至少有一种蠕虫。最常见的原生动物感染是贾第鞭毛虫（6%）和脆弱双变形虫（3%），以及蠕虫，钩虫（2%）。原生动物在< 18岁的难民中更常见（OR：2.2 [1.2-4.2]），而蠕虫在来自中亚南部（OR：8.0 [2.3-27.7]）和非洲（OR：5.9 [1.6-21.6]）的难民中更常见。在蠕虫中，蛔虫和钩虫主要集中在中南亚洲人（7例中的6例和11例中的10例），而粪类圆线虫主要见于非洲人（7例中的5例）。虽然出发前的经验性治疗方案在撒哈拉非洲可能有助于减少从该地区抵达难民的患病率，寄生虫感染仍然是常见的难民到美国与蠕虫感染在更具体的人群中发现。由于难民只代表了一小部分，最近的移民从流行的国家，目前的研究，在非难民群体也是必要的。
With continuing emigration from endemic countries, screening for parasitic infections remains a priority in U.S. communities serving refugee and immigrant populations. We report the prevalence of helminths and protozoa as well as demographic risk factors associated with these infections among 533 refugees seen at the Santa Clara County, California, Refugee Clinic between October 2001 and January 2004. Stool parasites were identified from 14% of refugees, including 9% found to have one or more protozoa and 6% found to have at least one helminth. Most common protozoan infections were Giardia lamblia (6%) and Dientamoeba fragilis (3%), and for helminths, hookworm (2%). Protozoa were more frequent in refugees < 18 years of age (OR: 2.2 [1.2-4.2]), whereas helminths were more common in refugees from South Central Asia (OR: 8.0 [2.3-27.7]) and Africa (OR: 5.9 [1.6-21.6]) when compared with refugees from Eastern Europe and the Middle East. Among helminths, Ascaris lumbricoides and hookworm were concentrated among South Central Asians (6 of 7 and 10 of 11 cases, respectively), whereas Strongyloides stercoralis was predominantly found in Africans (5 of 7 cases). Although predeparture empirical treatment programs in Saharan Africa may have helped to reduce prevalence among arriving refugees from this region, parasitic infection is still common among refugees to the United States with helminth infections found in more specific populations. As refugees represent only a fraction of recent immigrants from endemic countries, current studies in nonrefugee groups are also needed.
