It starts like a stomach bug. Then it keeps going.
Across the U.S., more people are talking about cyclosporiasis, a foodborne illness caused by the microscopic parasite Cyclospora cayetanensis. The infection is best known for one brutal symptom: frequent, watery, sometimes explosive diarrhea that can last far longer than the average bout of food poisoning.
One Michigan man described needing the bathroom every 15 to 30 minutes after symptoms escalated over a couple of days. His story, shared amid online discussions about the illness, captures why Cyclospora has suddenly become a high-anxiety search term for anyone dealing with a mysterious gastrointestinal illness.
Cyclospora Symptoms: More Than a Regular Stomach Bug
According to public health guidance, Cyclospora symptoms often include watery diarrhea, nausea, stomach cramps, bloating, gas, fatigue, appetite loss, and weight loss. Some people also report low-grade fever or flu-like aches.
The frustrating part is the stop-start pattern. Symptoms can improve, then return days later. Without proper treatment, cyclosporiasis may linger for weeks or even longer, which is one reason patients often end up at urgent care or calling their doctor after assuming it would pass on its own.
How Cyclospora Spreads Through Contaminated Food and Water
Cyclospora cayetanensis spreads when people ingest food or water contaminated with infected human feces. That sounds alarming because it is—but it’s also a reminder of how dependent modern food systems are on sanitation at every step, from farms and processing facilities to restaurants and home kitchens.
Unlike some stomach viruses, Cyclospora does not usually spread directly from person to person right away. The parasite needs time in the environment to become infectious. Outbreaks have often been associated with fresh produce, especially items eaten raw, because cooking can kill many pathogens while a quick rinse may not remove every microscopic risk.
Why Cyclosporiasis Cases Get Attention From the CDC and FDA
When a parasite shows up across multiple states, agencies such as the CDC and FDA track reports, investigate possible food sources, and look for patterns in what sick people ate. Those investigations can be complicated. Fresh ingredients move through long supply chains, and by the time patients are diagnosed, the original food may already be gone.
That delay matters. Cyclosporiasis is diagnosed through stool testing, but not every routine stool test automatically checks for Cyclospora. If you have persistent watery diarrhea, especially after eating fresh produce or food from a source later tied to an outbreak, it’s worth asking a healthcare provider whether specific parasite testing is needed.
When to Seek Medical Care for Explosive Diarrhea
Most people don’t need to panic over a short stomach illness. But explosive diarrhea that is frequent, persistent, or paired with dehydration symptoms should be taken seriously. Warning signs include dizziness, very dark urine, dry mouth, inability to keep fluids down, blood in stool, severe abdominal pain, or symptoms lasting more than a few days.
People who are pregnant, older adults, immunocompromised, or caring for young children should be especially cautious. Treatment is available, but the right medication depends on diagnosis and individual health factors, so this is not the moment to self-treat with random leftover antibiotics.
How to Reduce Your Risk of Cyclospora Infection
You can’t control every part of the food supply, but basic prevention still helps. Wash hands before handling food, rinse fresh produce under running water, keep raw and ready-to-eat foods separate, refrigerate perishable items promptly, and pay attention to outbreak notices from health agencies.
The bigger takeaway is simple: if a “stomach bug” feels unusually intense or refuses to quit, don’t just tough it out. Cyclospora is tiny, but the illness it causes can be disruptive, exhausting, and medically significant.
