The cyclosporiasis outbreak has turned deadly.

Two deaths from the parasite cyclospora have been reported in Michigan, which has recorded 12,218 total cases with 193 hospitalizations as of Aug. 5, according to the Michigan Department of Health & Human Services.

Both individuals had significant underlying health conditions that may have been impacted by cyclosporiasis and dehydration, according to a statement on the health department’s website. No additional information will be provided on the two deaths, according to the department.

By Aug. 7, 279 reported cases in Michigan indicated they had been hospitalized, and the total number of cases in the state climbed to 12,485.

On July 17, Taylor Farms voluntarily removed all iceberg lettuce sourced from central Mexico from the U.S. market.

Most people infected with cyclospora develop diarrhea, with frequent bowel movements. Other common symptoms include loss of appetite, weight loss, stomach cramps/pain, bloating, increased gas, nausea and fatigue. Vomiting, body aches, headache, and fever may be noted.

If not treated, the illness can lead to dehydration and severe complications that may require higher levels of care, according to the Food and Drug Administration.

The Centers for Disease Control and Prevention said in a statement on its website that it was aware of the reported deaths in Michigan. As of Aug. 3, the CDC was reporting at least 1,947 cases in nine states.

As of Aug. 7, that number had grown to 6,358 people in 15 states.

CDC is also investigating other outbreaks and illnesses of cyclosporiasis nationally unrelated to the outbreak.
