匐行疹综合征(沙蚕病或线幼虫皮炎)正成为从热带国家返回捷克许多旅游者的一个普遍问题。大多数旅游者是在海滩及其周围环境感染的。我们接触的大多数病人是由于受巴西钩虫或钩虫属的其它各类线幼虫感染所致,与类圆线虫属感染很少有共同点。狗通常被认为是线虫的储藏宿主。 Rana syndrome (silkworm disease or larval dermatitis) is becoming a common problem for many tourists returning from the tropical countries to the Czech Republic. Most tourists are infected at the beach and its surroundings. Most of the patients we come into contact with are caused by infection with other types of larvae of the Brazilian hookworm or hookworm genus, and have little in common with the infection with the genus Round-robin. Dogs are generally considered storage hosts for nematodes.
