Sporadic STEC O157 infection: secondary household transmission in Wales

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.
