In the Mediterranean area 2 subspecies of Echinococcus granulosus exist: E. g. equinus and E. g. granulosus. The latter is divided into sheep, cattle, pig and camel strains, the adult forms of which mainly occur in farm-dogs but sometimes in wild canidae. Some of these strains can infect man: namely, the sheep and the pig strain. The infectivity of the cattle strains for man is not certain. The epidemiological cycle is mainly a rural one, but it can become sylvatic or even urban. Thus, the epidemiological features of hydatidosis in the Mediterranean area are not basically different from the general epidemiology of the disease. But extensive rearing of sheep, combined with the carelessness and ignorance of people and with some particular habits, favours the maintenance of the infection.
在地中海地区存在细粒棘球绦虫的2个亚种：马型细粒棘球绦虫和普通细粒棘球绦虫。后者又分为绵羊、牛、猪和骆驼株，其成虫主要寄生于家犬，但有时也见于野生犬科动物。其中一些株可感染人类，即绵羊株和猪株。牛株对人类的感染性尚不确定。其流行周期主要在农村，但也可能变为森林型甚至城市型。因此，地中海地区包虫病的流行病学特征与该病的一般流行病学并无根本差异。但是，绵羊的广泛饲养，加上人们的粗心和无知以及一些特殊习惯，有利于感染的持续存在。
