Outbreaks in Illinois
Below are outbreaks, investigations, disease concerns, and increased activity in 2020 that include cases in Illinois or have a wide impact in Illinois.
The Illinois Department of Public Health has identified an increase in Cyclospora cases in Illinois since June 1, 2020. As of August 5, 2020, at least 257 laboratory confirmed domestically acquired cases have been reported to IDPH among Illinois residents. A public health investigation is being conducted to determine the source(s).
People can become infected with Cyclospora by consuming food (typically fruits and vegetables) or water contaminated with the parasite.
The most common symptom of Cyclospora infection is watery diarrhea. Other symptoms can include stomach cramps, nausea, vomiting, fatigue, loss of appetite, weight loss, muscle aches, and low-grade fever. Symptoms typically begin one to two weeks after exposure and can be treated with specific antibiotics. If not treated, the illness may last from a few days to a month or longer. Symptoms may seem to go away and then return one or more times (relapse). People that are experiencing symptoms of Cyclospora should contact their health care provider for testing.
A public health investigation is being conducted, including interviewing cases of Cyclospora to identify food exposures. Laboratories and health care providers should report cases promptly so public health workers can interview the cases as soon as possible.
In the United States, foodborne outbreaks of cyclosporiasis have previously been linked to various types of fresh produce such as raspberries, basil, cilantro, snow peas, and lettuce.
