Health officials are tracking new cases of cyclosporiasis, a foodborne infection that leads to severe gastrointestinal symptoms, including intense diarrhea.

More than 2,800 cases of cyclospora infection have been reported, largely concentrated in Michigan, state health officials reported Monday.

The outbreak has resulted in at least 86 hospitalizations, though no deaths have been reported

The US CDC is investigating thousands of possible cases across 34 states, as officials track down the source of the outbreak.

“You cannot thin a system, defer the tools that would speed it up, and then wonder why the public is left guessing,” writes epidemiologist Katrine Wallace.

Nearly 7,000 cases of cyclosporiasis are either confirmed or under investigation in the US - the source is still unknown.

Why fresh produce is the perfect vehicle for a parasite that needs a week to mature, and what the US outbreak tells us about its spread.

It took weeks for the CDC to issue a health advisory over the growing number of cyclosporiasis cases.

Cases have hit record levels, and scientists are racing to pinpoint where the Cyclospora parasite entered the food supply.
