Cases of cyclosporiasis have more than tripled in Summit County since July 15.
As of July 21, Summit County Public Health said it is currently evaluating 224 cases since June 20. This number has grown from four as of July 2 and 65 as of July 15.
As cases rise, a Summa Health spokesperson said the hospital system has been able to evaluate and discharge the majority of patients with the infection, and a smaller number have required hospital admission.
As of July 21, Ohio’s infectious disease tracker shows 1,303 cyclosporiasis cases in the state since June 20.
Nationally, since May 1, the CDC has received reports of 1,645 confirmed cases of cyclosporiasis. The agency is aware of more than 5,100 cases that require further analysis to confirm, as of July 13.
More recent data on the number of nationwide cases as of July 21 was not yet available from the CDC.
Cyclosporiasis at Summa Health
Summa Health has seen cases over the past several weeks in inpatient and outpatient settings, spokesman Mike Bernstein said. The system has also had an increase in emergency department visits and a higher volume of laboratory testing.
“Although we typically observe an increase in cyclosporiasis cases between May 1 and Aug. 31, the number of cases reported this year has exceeded those seen during the same period in 2025,” Bernstein said in a statement.
Cyclosporiasis at the Cleveland Clinic
A spokesperson for the Cleveland Clinic said the hospital has had very few patients hospitalized due to cyclosporiasis.
The hospital is encouraging patients with cyclosporiasis symptoms to start with an Express Care Virtual Visit, contact their primary care provider or visit one of their express care or urgent care centers.
From there, a provider can evaluate symptoms, order stool testing and prescribe treatment if needed, spokeswoman Beth Hertz said.
Has the cyclosporiasis outbreak cause been found yet?
A lettuce sample from Taylor Farms tested positive for cyclospora on July 18, but the Food and Drug Administration said on July 19 that the test was found to be a false positive.
Taylor Farms recalled its lettuce products served at Taco Bell restaurants and certain bagged lettuce products sold at Walmart under the Marketside brand for possibly being contaminated with cyclospora.
Its implicated shredded iceberg product was distributed June 29 through July 16 in almost 30 states, including Ohio.
Investigations continue to find the source of the outbreak.
