During the period 1974-91 large numbers of Southeast Asian immigrants and refugees were resettled in Western countries, including Australia. Health screening during this period demonstrated that intestinal parasite infections were common. A cross-sectional survey of 95 Laotian settlers who arrived in Australia on average 12 years prior to the study was conducted to determine if chronic intestinal parasite infections were prevalent in this group. Twenty-three participants had positive Strongyloides stercoralis test results (22 with positive serology, including I with S. stercoralis larvae detected in faeces and another with larvae and equivocal serology). Of these 23 participants, 18 (78%) had an elevated eosinophil count. Two patients had eggs of Opisthorchis spp. identified by faecal microscopy. The detection of chronic strongyloidiasis in Laotian settlers is a concern because of the potential serious morbidity associated with this pathogen.
在1974年至1991年期间，大量东南亚移民和难民在包括澳大利亚在内的西方国家重新定居。这一时期的健康筛查表明肠道寄生虫感染很常见。对平均在研究前12年抵达澳大利亚的95名老挝定居者进行了一项横断面调查，以确定该群体中慢性肠道寄生虫感染是否普遍存在。23名参与者粪类圆线虫检测结果呈阳性（22名血清学检测呈阳性，其中1名粪便中检测到粪类圆线虫幼虫，另1名幼虫检测呈阳性但血清学检测结果不明确）。在这23名参与者中，18名（78%）嗜酸性粒细胞计数升高。两名患者通过粪便显微镜检查发现有华支睾吸虫卵。老挝定居者中慢性粪类圆线虫病的检出令人担忧，因为这种病原体可能会引发严重疾病。
