Cyclospora: GI Associates shares advice on symptoms, prevention, when to seek care

WISCONSIN – Cyclosporiasis, a foodborne parasitic illness, has been making headlines in recent weeks, leaving many people wondering if they should be concerned.

While infections remain relatively uncommon in Wisconsin, GI Associates wants people to know how to reduce their risk, recognize the symptoms, and when it's time to seek medical care.

GI Associates is the largest independent gastroenterology practice, providing complete digestive health care in central and northern Wisconsin. With board-certified gastroenterologists and a compassionate team of specialists, GI Associates provides high-quality, patient-centered care that improves the health and well-being of the communities it serves.

According to the Centers for Disease Control and Prevention (CDC), 1,645 cyclosporiasis cases had been reported in the United States as of July 13, with Michigan reporting the highest number of cases this year. Wisconsin has 43 reported cases as of July 10.

"Cyclosporiasis is an illness caused by the Cyclospora parasite, which infects the small intestine and can lead to gastrointestinal symptoms," said Keaton Jones, MD, Gastroenterologist at GI Associates. "Most infections are linked to contaminated imported fresh produce, although it can also be contracted from contaminated water while traveling in countries where the parasite is more common."

What is cyclosporiasis?

Cyclospora is a microscopic parasite that causes cyclosporiasis, a gastrointestinal illness that develops after someone consumes contaminated food or water. Unlike viruses that spread easily from person to person, cyclospora generally is not passed directly between people.

Symptoms usually develop about one week after exposure, although they can appear anywhere from two to 14 days later. Common symptoms include:

• Frequent, watery diarrhea
• Loss of appetite
• Abdominal cramping or bloating
• Fatigue
• Nausea and vomiting
• Low-grade fever

"Cyclospora infections are uncommon, but the recent reports are a good reminder that not every stomach illness is the same," Dr. Jones said. "If your symptoms are severe, don't improve within a few days, or seem to get better and then return, it's important to talk with your healthcare provider."

Reducing your risk

People do not need to avoid fresh fruits and vegetables. They remain an important part of a healthy diet. One of the simplest ways to reduce your risk is to thoroughly wash fresh fruits and vegetables under running water before eating or preparing them.

If you're at higher risk (older adults, people with weakened immune systems, those undergoing cancer treatment, transplant recipients or anyone with chronic medical conditions), choose foods that are less likely to carry cyclospora or that can be made safer by cooking.

Good choices include:

• Cooked vegetables rather than raw.
• Fruits with thick peels that you remove yourself.
• Frozen vegetables that will be cooked.
• Canned fruits and vegetables.
• Produce that has been thoroughly washed under running water.

Use extra caution with:

• Bagged salads and leafy greens.
• Fresh herbs such as cilantro and basil.
• Ready-to-eat raw vegetable trays.
• Berries that can't be scrubbed or peeled.
• Imported fresh produce.
• Unwashed fruits and vegetables.

When to see a healthcare provider

The good news is that a cyclospora infection is treatable, usually with prescription antibiotics. Early diagnosis can help shorten the illness and prevent complications.

Anyone experiencing severe diarrhea, dehydration, significant weight loss, persistent gastrointestinal symptoms or symptoms that improve and then return should contact a healthcare provider.
