Cyclospora parasite cases in Kentucky, health officials warn

LEXINGTON, Ky. (WKYT) – Health officials are warning residents about a rise in Cyclospora cases, a parasite that causes an intestinal illness known as cyclosporiasis and can leave people sick for weeks.

The Kentucky Department for Public Health reported 67 cases between June 14 and July 2 — nearly double the approximately 35 cases the state typically sees in an entire year. While cases normally rise in the spring and summer months, Kentucky is among several states seeing a larger-than-typical increase.

Cases likely undercounted, health official says

Cassie Prather of the Woodford County Health Department said the reported numbers are likely an undercount.

“At this point, we have an underreported number of cases because a lot of people will deal with this and their immune system can kick it in a few days,” Prather said. “For those with a suppressed immune system it can lead to quick dehydration or even a hospital visits if they’re dealing with symptoms that don’t go away for 3-5 days.”

How the parasite spreads

People can become infected after eating or drinking contaminated food or water. Fresh produce has been linked to outbreaks in the United States, but the CDC says it is still working to pinpoint the cause of the current increase.

Symptoms and timeline

Symptoms often begin about a week after exposure but can appear as soon as two days or more than two weeks later. The most common symptom is watery diarrhea. People may also experience stomach cramps, nausea, fatigue, bloating, and weight loss. Symptoms can last weeks and sometimes return after improving.

“You’re going to endure stomach cramps, nausea, sometimes you can have a low-grade fever with that,” Prather said.

Prevention guidance

Public health experts urge people to follow food-safety guidelines to reduce the risk of cyclosporiasis and other intestinal illnesses. That includes washing hands with soap and water before and after handling raw fruits and vegetables, and refrigerating cut, peeled, or cooked fruits and vegetables within two hours.

Health officials say people whose symptoms last more than a few days, keep returning, or cause signs of dehydration should contact a healthcare provider for evaluation and possible testing.
