Duration of shedding and secondary household transmission of shiga toxin-producing Escherichia coli O26 during an outbreak in a childcare center, Oregon, october-december 2010

Abstract

We assessed shedding duration and secondary household transmission of Shiga toxin 1-positive Escherichia coli O26 during a childcare-associated outbreak. No severe illness was noted. Shedding duration was 15-46 days (median, 29). No secondary transmission to household members was identified. Value of isolating asymptomatic infected children with this low-virulence infection remains uncertain.
