Of these 353 cases, at least 21 people reportedly have been hospitalized.

Cyclospora is a parasite that is spread by people ingesting something that was contaminated with feces. Symptoms of cyclosporiasis may include: watery diarrhea, loss of appetite, weight loss, cramping, bloating, increased gas, nausea, and fatigue.

Previous outbreak investigations have implicated various types of fresh produce, but no food items have been implicated to date. Cases in this outbreak are defined as laboratory-confirmed Cyclospora infection in a person who became ill in June or July 2013, and had no history of travel outside of the United States or Canada during the 2 weeks prior to illness.

More cases are currently being investigated and the CDC will continue to update the public as states confirm them.
