As of April 8, 2019, 96 people infected with the outbreak strain of E. coli O103 have been reported from five states. CDC is reporting the 96 illnesses that the PulseNet laboratory network has confirmed are part of this outbreak. States are investigating additional illnesses that might be a part of this outbreak.

Illnesses started on dates from March 2, 2019, to March 26, 2019. Ill people range in age from 1 to 81 years, with a median age of 17. Fifty-one percent are female. Of 67 people with information available, 11 (16%) have been hospitalized. No deaths and no cases of hemolytic uremic syndrome have been reported.

This investigation is still ongoing and a specific food item, grocery store, or restaurant chain has not been identified as the source of infections. State and local public health officials are interviewing ill people to determine what they ate and other exposures in the week before their illness started. Federal and state regulatory officials use that information to guide efforts to identify a contaminated food and trace it to its source.
