The ill people live in seven states — Florida, Kansas, Missouri, Ohio, Pennsylvania, Tennessee and Wisconsin — and the Center for Disease Control believes the victims contracted the illness from puppies sold at Petland stores.

“Petland is cooperating with public health and animal health officials to address this outbreak,” the CDC said in a statement.

The CDC says the illness is one of the most common causes of diarrhea in the United States, infecting 1.3 million people every year.

While dogs who are infected might present as perfectly healthy, they can suffer from “diarrhea, vomiting, or a fever.” The CDC warns people to limit their exposure to the animals and to wash hands frequently. Symptoms in humans include “diarrhea, sometimes bloody; fever; stomach cramps; nausea and vomiting.”
