A significant reduction in the prevalence of both intestinal and urinary schistosomiasis has occurred in all emirates (districts) in all 12 foci of the infection distributed in five regions of Saudi Arabia. Infection with Schistosoma mansoni has dropped in foci of the infection in the Central Region (Riyadh and Hail) and in all foci within the western provinces. Reduction has also occurred in the prevalence of S. haematobium in foci of Gizan, the Red Sea coastal areas and parts of Madinah. The disease no longer exists around Riyadh. The overall prevalence in all 12 foci of infection in Saudi Arabia dropped gradually from 11% in 1983 to 1.9% in 1987. At present the infection rates among expatriates are much higher than among Saudis in most foci. The number of emirates which had rates of 10% or more has dropped from 46 in 1983, to nil in 1987, and the number with rates of 5-10% from 25 in 1983 to one in 1987. The overall prevalence is presently between 1 and less than 5% in 73 emirates and less than 1% in 41 emirates. Significant reduction was observed in most villages in each district. Higher infection rates may still be present in a few areas within one or two emirates not surveyed in the last 2-3 years. The potential danger of a resurgence of the disease due to the development of water resources and the presence of a great number of infected expatriates is significant.
在沙特阿拉伯五个地区分布的所有12个感染疫点的所有酋长国（地区），肠道和泌尿血吸虫病的流行率均显著下降。曼氏血吸虫感染在中部地区（利雅得和哈伊勒）的感染疫点以及西部省份的所有疫点均有所下降。埃及血吸虫在吉赞、红海沿岸地区和麦地那部分地区的疫点流行率也有所下降。利雅得周边地区已不再存在该病。沙特阿拉伯所有12个感染疫点的总体流行率从1983年的11%逐渐降至1987年的1.9%。目前，在大多数疫点，外籍人员的感染率远高于沙特人。感染率达到或超过10%的酋长国数量从1983年的46个降至1987年的零个，感染率在5%至10%之间的酋长国数量从1983年的25个降至1987年的1个。目前，73个酋长国的总体流行率在1%至不到5%之间，41个酋长国的总体流行率不到1%。在每个地区的大多数村庄都观察到显著下降。在过去两到三年未进行调查的一两个酋长国的少数地区，可能仍存在较高的感染率。由于水资源开发以及大量受感染的外籍人员的存在，该病卷土重来的潜在危险很大。
