Cyclospora outbreak reaches Nebraska as health officials investigate source

A nationwide outbreak of the parasite Cyclospora has reached Nebraska, according to health experts at CHI Health.

While only a handful of cases have been identified in the state, doctors say the true number of infections may be higher because many people recover at home without being tested.

Cyclospora is a microscopic parasite that can contaminate food and cause gastrointestinal illness. Health officials are still investigating the source of the current outbreak and have not identified a specific food item responsible.

Previous Cyclospora outbreaks have been linked to fresh produce, including pre-cut salad mixes, cilantro, basil, raspberries, snow peas and green onions.

Dr. Renuga Vivekanandan with CHI Health says the parasite can be difficult to remove because it can survive in small, porous areas of some produce.

“Even though you’re washing it, they can remain there,” Vivekanandan said. “Ideally, if you buy produce whole, you can wash it thoroughly yourself.”

Symptoms of Cyclospora typically appear about seven days after exposure but can take up to two weeks, making it difficult for investigators to determine where someone was infected.

Symptoms can include prolonged diarrhea, fatigue, dehydration, muscle weakness and stomach discomfort.

Doctors say most people recover without hospitalization, but young children, older adults and people with weakened immune systems face a higher risk of complications.

Unlike some stomach illnesses, Cyclospora can be treated with antibiotics. Health experts say the most common treatment is trimethoprim-sulfamethoxazole, also known as Bactrim.

Doctors recommend contacting a healthcare provider if symptoms do not improve and say staying hydrated is especially important.

Health experts say Cyclospora typically does not spread easily from person to person.

“If somebody else in your household has this, you’re not necessarily going to get it,” said Dr. Dave Quinby, an infectious disease physician with CHI Health. “Handwashing is always good, but this tends not to go person to person well at all.”

Until investigators identify the source of the outbreak, doctors recommend buying whole produce when possible, washing fruits and vegetables thoroughly and cooking foods when appropriate.

According to the CDC, more than 843 confirmed cases and approximately 1,500 probable cases have been reported nationwide. Eighty-six people have been hospitalized, and no deaths have been reported.
