Recurrent, prolonged, multicommunity outbreaks of daycare-associated Shigella sonnei infections, which occur in communities approximately every 7 to 9 years, continue to present management dilemmas to public health officials.1,2 An area comprising 4 counties and 8 health jurisdiction regions surrounding the greater metropolitan area of Cincinnati, Ohio, experienced an outbreak of 1642 S sonnei cases between May 1 and September 7, 2001. We interviewed a random sample of 97 families who had at least 1 member with culture-confirmed S sonnei to determine the risk factors for transmission. Of the 56 patients in our random sample who were 5 years or younger, 53 (95%) were symptomatic, and 55 (99%) attended daycare. Ten of the adult patients in the family sample were daycare workers. All patients received a course of antimicrobial therapy, and 3 (3%) required hospitalization.
