Healthline‘Explosive Diarrhea Parasite’ Spreading Across 31 States, CDC Warns. How to Reduce Your Risk

📡 Surveillance / Emerging Signal

Health officials are investigating a multistate increase in cyclosporiasis, a parasitic infection caused by Cyclospora that can lead to watery, prolonged diarrhea, abdominal cramping, nausea, bloating, and appetite loss. According to reporting cited in the article, 31 states have reported cases, with Michigan experiencing a particularly large outbreak involving thousands of reported infections. Investigators are working to identify the source, with leafy greens and other fresh produce under consideration as possible contributors.

Patient Counseling Points

• Educate patients that persistent watery diarrhea lasting days to weeks warrants medical evaluation.
• Reinforce that the greatest risk of illness complications is often dehydration, especially among older adults, young children, immunocompromised patients, and those with chronic health conditions.
• Encourage careful food handling practices, including washing fresh produce before preparation and consumption.
• Remind patients that symptoms may begin about one week after exposure, making the source difficult to identify.
• Advise travelers and patients with persistent gastrointestinal symptoms to seek evaluation rather than relying solely on over-the-counter remedies.

Patient Care Applications

• Recognize prolonged watery diarrhea as a potential presentation of cyclosporiasis during the current outbreak activity.
• Assess hydration status carefully in patients presenting with gastrointestinal illness.
• Monitor vulnerable populations for worsening symptoms, electrolyte abnormalities, and dehydration-related complications.
• Educate patients on food safety practices and the importance of reporting persistent symptoms.
• Coordinate testing and escalation when diarrheal illness persists beyond expected timeframes or is accompanied by severe symptoms.
