A multi-state E. coli outbreak associated with romaine lettuce in sandwiches from Wendy's has grown 

with dozens more infections reported in the past week, according to federal health officials. 

Since Aug. 17, when the outbreak was first publicized, 55 more illnesses in the outbreak have been reported to the U.S. Centers for Disease Control and Prevention 

bringing the total number of reported infections to 84, the agency said Thursday. 

Among those, 38 people have been hospitalized, including eight people in Michigan who have a type of kidney failure called hemolytic uremic syndrome, the CDC said 

The infections have been reported to the CDC from four states: Michigan (53); Ohio (23); Indiana (six); and Pennsylvania (two). 

CDC investigators are working to confirm the source of the outbreak, though many of those who became sick reported eating at Wendy's, the CDC said. 

A specific food has not yet been confirmed as the source of this outbreak 

but many sick people reported eating sandwiches with romaine lettuce at Wendy's restaurants in Indiana
