A list of the states and the number of cases in each can be found on the Case Count Map page. Illnesses started on dates ranging from March 13, 2018 to May 2, 2018. Ill people range in age from 1 to 88 years, with a median age of 29. Sixty-five percent of ill people are female. Of 157 people with information available, 75 (48%) have been hospitalized, including 20 people who developed hemolytic uremic syndrome, a type of kidney failure. One death was reported from California. Illnesses that occurred after April 21, 2018, might not yet be reported due to the time it takes between when a person becomes ill with E. coli and when the illness is reported.

Nine ill people were hospitalized, including two people who developed hemolytic uremic syndrome, a type of kidney failure. One death was reported from California. By the end of the investigation, 15 people had been interviewed about the foods they ate and other exposures in the week before illness began. Ninety-three percent of ill people reported eating any type of leafy greens. Fifty-five percent of ill people specifically reported eating romaine lettuce. This percentage was not significantly higher than results from a survey[PDF - 29 pages] of healthy people in which 46% reported eating romaine lettuce in the week before they were interviewed.

Whole genome sequencing (WGS) performed on clinical isolates from ill people showed that the isolates were closely related genetically.

Public health investigators used the PulseNet system to identify illnesses that may be part of this outbreak. PulseNet, coordinated by CDC, is the national subtyping network of public health and food regulatory agency laboratories. PulseNet performs DNA fingerprinting on STEC bacteria isolated from ill people by using techniques called pulsed-field gel electrophoresis (PFGE) and whole genome sequencing (WGS). CDC PulseNet manages a national database of these DNA fingerprints to identify possible outbreaks. In this outbreak, the outbreak strain was defined by PFGE. Eleven people infected with the outbreak strain of STEC O157:H7 were reported from five states. A list of the states and the number of cases in each can be found on the Case Count Map page. Illnesses started on dates ranging from June 27, 2016 to September 10, 2016. Ill people ranged in age from 1 year to 74, with a median age of 32. Forty-five percent of ill people were female.
