A total of 109 people infected with the outbreak strain of E. coli O157:H7 were reported from 6 states. Indiana 11, Kentucky 2, Michigan 67, New York 1, Ohio 24, Pennsylvania 4.

Sick people range in age from 1 to 94 years, with a median age of 22 years, and 55% are male. Of 97 people with information available, 52 have been hospitalized. Thirteen people have developed a type of kidney failure called hemolytic uremic syndrome. No deaths have been reported at this time.

The true number of sick people in this outbreak is likely higher than the number reported, and the outbreak may not be limited to the states with known illnesses. This is because some people recover without medical care and are not tested for E. coli.

State and local public health officials have been interviewing people about the foods they ate in the week before they got sick. Among 82 people who have been interviewed, 68 (83%) reported eating at a Wendy’s restaurant in the week before their illness started.

The Wendy’s restaurants where sick people ate are in Indiana, Kentucky, Michigan, New Jersey, Ohio, and Pennsylvania. People reported eating a variety of menu items, including burgers and sandwiches. Of 68 people with detailed information about what they ate at Wendy’s, 46 (68%) reported eating romaine lettuce served on burgers and sandwiches.

Investigators continue to analyze data at the ingredient level to determine if there are any other possible foods that could be the source of the outbreak.

Public health investigators used the PulseNet system to identify illnesses that were part of this outbreak. CDC PulseNet manages a national database of DNA fingerprints of bacteria that cause foodborne illnesses. DNA fingerprinting is performed on bacteria using a method called whole genome sequencing (WGS). WGS showed that bacteria from sick people’s samples were closely related genetically. This suggests that people got sick from eating the same food.

73 are 0 Single Nucleotide Polymorphisms (SNPs). This means that there are no genetic variations in the genotype "fingerprint"; they all match and most likely came from the same food that made everyone sick.
