Al-Baha is an area with large influx of expatriate workers in Saudi Arabia. This study was carried out from October 2009 to January 2011 on expatriate workers (2000) to determine the prevalence of parasitosis. Urine and stool samples were collected and specifically examined. The results showed that 1079 (53.95%) were infected with one or up to ten parasitic species. Trichuris trichiura had the highest prevalence 190 (17.6%). Other helminthes were Ascaris lumbricoides 179 (16.58%), Ancylostoma duodenal 163 (15.10%), Hymenolepis nana 120 (11.12%), Taenia saginata 119 (11.02%), Strongyloides stercoralis 28 (2.59), Enterobius vermicularis 16 (1.48%), and Schistosoma mansoni 4 (0.37%). Protozoan parasites were Giardia lamblia 152 (14.09%) and Enta-moeba histolytica 108 (10.0%). Besides, Fasciola species was detected in an Egyptian worker and Dicrocelium dendriticum in one Syrian worker. Parasitic infections were higher among Indonesian people 447 (41.42%) followed by Indian 247 (22.89%), Bangladeshis 118 (10.93%), Philippines 96 (8.89%), Pakistani 94 (9.71%), Seri-Lankan 55 (5.09 %) and lastly Egyptian & Syrian 22 (2.03%) workers. The occupational imperatives, beliefs and general life style were contributing factors to the prevalence of parasites among the workers in Al-Baha.
巴哈是沙特阿拉伯外籍工人大量涌入的地区。本研究于2009年10月至2011年1月对外籍工人（2000名）进行，以确定寄生虫病的患病率。收集尿液和粪便样本并进行专项检查。结果显示，1079人（53.95%）感染了一种或多达十种寄生虫。鞭虫的患病率最高，为190人（17.6%）。其他蠕虫包括蛔虫179人（16.58%）、十二指肠钩虫163人（15.10%）、微小膜壳绦虫120人（11.12%）、牛带绦虫119人（11.02%）、粪类圆线虫28人（2.59%）、蛲虫16人（1.48%）和曼氏血吸虫4人（0.37%）。原生动物寄生虫为蓝氏贾第鞭毛虫152人（14.09%）和溶组织内阿米巴108人（10.0%）。此外，在一名埃及工人中检测到肝片吸虫，在一名叙利亚工人中检测到枝双腔吸虫。印度尼西亚人寄生虫感染率较高，为447人（41.42%），其次是印度人247人（22.89%）、孟加拉国人118人（10.93%）、菲律宾人96人（8.89%）、巴基斯坦人94人（9.71%）、斯里兰卡人55人（5.09%），最后是埃及和叙利亚工人22人（2.03%）。职业需求、信仰和一般生活方式是巴哈地区工人寄生虫感染率高的促成因素。
