One hundred and twenty-four persons, nearly the entire population of a rural village in Hidalgo State, were screened for intestinal parasites and clinical or serologic (ELISA) evidence of Taenia solium cysticercosis. Heads of households were questioned about dietary and other practices that might lead to pork tapeworm transmission, and soil samples were examined for helminth eggs. Twenty-five percent of local pigs had cysticerci visible by examination of the undersurface of their tongues. Four persons passed taeniid eggs, 7 were seropositive, and 10 gave medical histories suggestive of neurodysticercosis. Most seropositive persons were not symptomatic and the reverse was also true. The clustered distribution of infected pigs, tapeworm carriers, and persons with serologic or clinical evidence of cysticercosis suggested intrahousehold transmission. Dietary and sanitary practices were generally optimal for transmission of pork tapeworm. No cattle were kept in the village and beef was rarely eaten. This preliminary report attempts to characterize T. solium transmission in communities with endemic disease in rural Mexico and illustrates some of the methodological problems faced by epidemiologists who study this disease.
对伊达尔戈州一个乡村几乎全部的124人进行了肠道寄生虫筛查以及猪带绦虫囊尾蚴病的临床或血清学（酶联免疫吸附测定）证据检查。询问了户主可能导致猪肉绦虫传播的饮食及其他行为，并对土壤样本进行了蠕虫卵检测。通过检查当地25%的猪舌头底面，发现有囊尾蚴。4人排出带绦虫卵，7人血清学呈阳性，10人有提示神经囊尾蚴病的病史。大多数血清学呈阳性的人没有症状，反之亦然。感染猪、绦虫携带者以及有囊尾蚴病血清学或临床证据的人呈聚集分布，提示家庭内传播。饮食和卫生习惯总体上有利于猪肉绦虫的传播。该村庄未饲养牛，很少食用牛肉。本初步报告试图描述墨西哥农村地方病社区猪带绦虫的传播情况，并说明了研究该疾病的流行病学家所面临的一些方法学问题。
