As of May 30, 2018, there are 197 cases in 35 states: Alaska (8), Arkansas (1), Arizona (9), California (45), Colorado (3), Connecticut (2), Florida (1), Georgia (5), Idaho (11), Illinois (2), Iowa (1), Kentucky (1), Louisiana (1), Massachusetts (4), Michigan (5), Minnesota (12), Mississippi (1), Missouri (1), Montana (9), Nebraska (1), New Jersey (8), New York (10), North Carolina (1), North Dakota (3), Ohio (7), Oklahoma (1), Oregon (1), Pennsylvania (24), South Dakota (1), Tennessee (3), Texas (3), Utah (1), Virginia (1), Washington (7), and Wisconsin (3).

Illnesses started on dates ranging from March 13, 2018 to May 12, 2018. Ill people range in age from 1 to 88 years, with a median age of 29. Sixty-eight percent of ill people are female. Of 187 people with information available, 89 (48%) have been hospitalized, including 26 people who developed hemolytic uremic syndrome, a type of kidney failure. Five deaths have been reported from Arkansas (1), California (1), Minnesota (2), and New York (1).

As of 1 PM (ET) October 6, 2006, Friday, 199 persons infected with the outbreak strain of E. coli O157:H7 have been reported to CDC from 26 states.

Among the ill persons, 102 (51%) were hospitalized and 31 (16%) developed a type of kidney failure called hemolytic-uremic syndrome (HUS). One hundred forty-one (71%) were female and 22 (11%) were children under 5 years old. The proportion of persons who developed HUS was 29% in children (<18 years old), 8% in persons 18 to 59 years old, and 14% in persons 60 years old or older. Among ill persons who provided the date when their illnesses began, 80% became ill between August 19 and September 5. The peak time when illnesses began was August 30 to September 1- 31% of persons with the outbreak strain became ill on one of those 3 days.

Three deaths in confirmed cases have been associated with the outbreak. One was in an elderly woman from Wisconsin. Yesterday, Idaho confirmed that stool samples from a 2-year-old child with HUS who died on September 20 contained E. coli O157 with a “DNA fingerprint” pattern that matches the outbreak strain. Today, Nebraska reported the death of an elderly woman with an illness compatible with E. coli O157 infection who consumed raw spinach; E. coli O157 with the outbreak strain “DNA fingerprint” was detected in the remaining spinach. Maryland is investigating a suspect case in an elderly woman who died on September 13 and had recently consumed fresh spinach. E. coli O157 was cultured from her stool, but “DNA fingerprinting” has not been possible.
