Age-prevalence of Strongyloides stercoralis infection was studied in six areas of Okinawa, Japan. In all localities, most of the infected inhabitants were aged over 40 years of age and females were less infected than males. The peak prevalence was found in inhabitants in their fifties in high endemic groups and shifted to higher age in lower endemic groups. This age-prevalence pattern resembles more that of schistosome infections than that of other gastrointestinal helminthic infections.
在日本冲绳的六个地区研究了粪类圆线虫感染的年龄患病率。在所有地区，大多数受感染居民年龄超过40岁，女性感染率低于男性。在高流行组中，五十多岁的居民患病率最高，而在低流行组中，患病率高峰年龄则更高。这种年龄患病率模式与血吸虫感染的模式更为相似，而非其他胃肠道蠕虫感染的模式。
