Parasitic stomach illness cyclosporiasis spreading across 30+ US states

A parasitic gut illness called cyclosporiasis is surging nationwide, with cases reported in more than 30 states.

A parasitic stomach illness is spreading across the United States, with more than 30 states now reporting cases of cyclosporiasis — a disease known for causing severe gastrointestinal symptoms. The illness is caused by Cyclospora cayetanensis, a microscopic parasite typically contracted by consuming contaminated food or water. Cyclosporiasis can produce prolonged, watery diarrhea, stomach cramps, nausea, and fatigue, sometimes lasting weeks if untreated. Outbreaks in the US have historically been linked to imported fresh produce such as raspberries, basil, and salad mixes. The current surge appears to span a broad geographic footprint, affecting states in multiple regions of the country.

Why it matters

Cyclosporiasis outbreaks can affect large numbers of people rapidly when a contaminated food source reaches wide distribution networks. Identifying and removing the source is critical to containing spread.

What's next

Health authorities are expected to investigate the food or water source driving the outbreak and may issue specific consumption warnings as the investigation progresses.

• More than 30 states have reported cyclosporiasis cases in the current surge
• Cyclosporiasis is caused by the parasite Cyclospora cayetanensis

Bias & framing notes

All five sources carry identical text under an apparent CNN/CDC wire slug ('0711_CDC_CNN'), offering no independent reporting or additional detail. The underlying information likely originates from a CDC or CNN report, but without access to that primary source, specific figures and context cannot be verified beyond what the shared wire copy states.
