Abstract

We conducted a study to quantify and characterize household transmission of Shiga toxin (Vero cytotoxin)-producing Escherichia coli O157 (STEC O157) following sporadic infection in Wales. Through total population surveillance, we identified 83 index case-patients and their household contacts. We screened fecal samples submitted from household contacts for STEC O157 and calculated the household transmission rate for sporadic STEC O157 infection to be 4% to 15%. Household contacts in groups at high risk (particularly children under 5 years of age) present a risk of spreading the infection in the wider community.

摘要

我们开展了一项研究,旨在对威尔士偶发性感染后产志贺毒素(维罗细胞毒素)的大肠杆菌O157(STEC O157)的家庭传播进行量化和特征分析。通过全人群监测,我们确定了83例索引病例患者及其家庭接触者。我们对家庭接触者提交的粪便样本进行STEC O157筛查,并计算出散发性STEC O157感染的家庭传播率为4%至15%。高风险群体中的家庭接触者(尤其是5岁以下儿童)存在将感染传播至更广泛社区的风险。
