Echinostoma ilocanum is widespread among the Philippine Islands but only 3% of over 30,000 stools were found to be positive for eggs. The prevalence rates were highest in Ilocana populations of northern Luzon; 11% of over 7,000 stools examined, however, rates as high as 44% were found. Pila luzonica is eaten uncooked by some people and metacercariae from these snails developed into adults in a number of laboratory animals. Rats, mice and hamsters were the most susceptible with patent infections developing as early as 7 days and lasting for 328 days. There seems to be little disease in humans and animals infected with this parasite.
伊族棘口吸虫在菲律宾群岛广泛分布，但在3万多份粪便中，仅3%被发现虫卵呈阳性。患病率在吕宋岛北部的伊洛卡诺人群中最高；在检查的7000多份粪便中，有11%呈阳性，然而，发现患病率高达44%。一些人会生吃吕宋扁卷螺，这些螺中的后尾蚴在一些实验动物体内发育成成虫。大鼠、小鼠和仓鼠最易感染，早在7天就出现显性感染，持续328天。感染这种寄生虫的人和动物似乎很少发病。
