Health officials report a growing multistate cyclosporiasis outbreak in the United States, with the CDC and media outlets citing rising numbers of both confirmed and suspected cases this summer. Several reports say thousands of people are sick, and that some cases require medical care, as the investigation continues across a broad range of states.

The CDC has confirmed cases in a substantial share of the country and is investigating additional illnesses that may be linked to cyclosporiasis. One cluster of outlets cites confirmed case counts in the low thousands and additional suspected cases requiring testing, while others highlight suspected totals exceeding 10,000 or 11,000. NBC and the Guardian describe the outbreak as expanding to more states in recent updates, including figures that rise as investigations progress.

Outlets also differ in emphasis. Some focus on the breadth of state participation (ranging from nine to over 30 states), while others focus on investigation scope (laboratory-confirmed domestic cases versus additional cases under investigation). Reports generally describe cyclosporiasis as a foodborne illness associated with contaminated fresh produce or water, and some include guidance to limit exposure to potentially implicated foods while authorities continue testing.
