In an update on its website Wednesday, the CDC wrote that at least 275 residents of multiple states, including Iowa, Nebraska, Texas, Wisconsin, Georgia, Connecticut and New Jersey, have been diagnosed with a cyclospora infection. At least 10 people have reportedly been hospitalized.

The stomach bug, which causes diarrhea and other flu-like symptoms, could be linked to a foodborne illness, according to The Associated Press.

From an earlier AP report:

The Food and Drug Administration is investigating the cyclospora infections, which are most often found in tropical or subtropical countries and have been linked to imported fresh produce in the past.

The illness is usually spread when people ingest food or water contaminated with feces. The agency says it isn't yet clear whether the cases from all the states are linked.
