Florida health officials say they are now investigating 24 cases of a stomach bug that has infected people in 14 states.
The number of cases under investigation increased over the weekend, and now one person is in the hospital.
But Florida Department of Health officials said Monday they have still not found common links to restaurants or food ingredients that may have caused the outbreak.
The Centers for Disease Control and Prevention says most cyclospora infections around the country occurred from mid-June to early July. It's not clear whether the cases are all linked.
Cyclospora causes diarrhea and other flu-like symptoms. The illness spreads when people ingest foods or water contaminated with feces. Previous outbreaks of cyclospora infections have been linked to various types of fresh vegetables and berries.
