Michigan’s cyclosporiasis outbreak has risen to 572 confirmed cases, more than tripling from 170 reported earlier in the week, according to the Michigan Department of Health and Human Services.

The largest increase has been in the southwest region of the state, while officials said they had not identified a definitive source for the illness.

The outbreak comes as Michigan is one of 18 US states dealing with cyclosporiasis, a parasitic infection linked to severe diarrhea and closely monitored by federal and state health agencies.

The tiny culprit behind the turmoil

Cyclosporiasis is caused by the microscopic parasite Cyclospora cayetanensis and is typically spread when people consume food or water contaminated with feces.

The CDC says the illness usually causes watery diarrhea with frequent and sometimes explosive bowel movements. The agency also notes that symptoms may last from a few days to more than a month and can fade before returning.

In its public guidance, the CDC says cyclosporiasis is not usually life-threatening, but it can still cause significant illness, especially when dehydration develops.

The hunt for the source presses on

The outbreak has renewed attention on fresh produce, which has been linked to previous cyclosporiasis investigations in the United States. The CDC says US outbreaks have been tied to various types of fresh produce.

Earlier data showed 145 cases across 17 states between May 1 and June 16, including 20 hospitalizations. New York, Texas, Illinois, and Michigan were among the hardest-hit states in the national count.

Investigators have not said the Michigan outbreak is tied to a single product, and health officials continue to trace possible food sources.

Prudence, not panic, is the order of the day

Health guidance remains focused on food safety and early treatment. The CDC advises people to avoid food or water that may contain feces, wash fresh produce thoroughly, and recognize that direct person-to-person transmission is unlikely.

The infection is usually treated with antibiotics, and rest and fluids are important to prevent dehydration. Officials are urging anyone who becomes ill to contact a health care provider and their local health department.

The source of the Michigan outbreak has still not been pinned down.
