CDC, several states, and the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA-APHIS) are investigating a multistate outbreak of multidrug-resistant Campylobacter infections.
Campylobacter bacteria isolated from clinical samples from people sickened in this outbreak are resistant to commonly recommended, first-line antibiotics. This means it may be difficult to treat these infections with the antibiotics usually prescribed for Campylobacter infections.
Since the last update on October 30, 2017, 30 more ill people have been reported from 11 states. The most recent illness began on October 23, 2017.
As of December 12, 2017, 97 people with laboratory-confirmed infections or symptoms consistent with Campylobacter infection have been linked to this outbreak. Illnesses have been reported from 17 states.
Twenty-two (24%) of 91 ill people with available information have been hospitalized. No deaths have been reported.
Illnesses started on dates ranging from June 17, 2016 to October 23, 2017.
Epidemiologic and laboratory evidence indicates that contact with puppies sold through Petland stores is a likely source of this outbreak.
