Cyclospora is spreading in the U.S., necessitating caution during meals and travels. This parasitic infection can cause severe diarrhea lasting for weeks.

Confirmed and suspected cases are being reported in several areas. Health authorities are conducting epidemiological investigations.

Common symptoms include diarrhea and abdominal pain, and the symptoms can be severe enough to lead to dehydration. Fever and fatigue may accompany these symptoms.

Transmission is known to occur through contaminated food or water, with fresh vegetables and raw fruits being cited in related cases.

Prevention includes frequently washing hands with running water and thoroughly cleaning or cooking vegetables and fruits if possible. Avoid foods of uncertain hygiene.

If symptoms persist, one should seek diagnostic testing at a medical institution. If diarrhea and dehydration continue for weeks, prompt medical attention is recommended.
