Nearly 7,000 people in the United States may have contracted cyclosporiasis, a parasitic foodborne illness that can cause weeks of intestinal unrest and diarrhea, according to the latest federal figures released on July 15, 2026.

The Centers for Disease Control and Prevention (CDC) reported 1,645 lab-confirmed domestic cases, with an additional 5,100 cases currently under investigation. This investigation reflects a substantial increase in potential cases, prompting heightened public health attention.

Cyclosporiasis is known for causing prolonged gastrointestinal symptoms, and the CDC continues to monitor the situation closely to determine the outbreak's source and contain its spread.
