Douglas County, Nebraska reports a rapid increase in cyclospora infections, with 27 confirmed cases and 12 unconfirmed cases in the past four days, and epidemiologists say eating at Taco Bell is the most common exposure among those interviewed as they work with state and federal partners to determine links to the broader multistate outbreak. Authorities note that Taco Bell has been connected to the national cyclospora investigation and that the county is coordinating with federal agencies while continuing to assess local sources and exposures, including the impact of lettuce recalls.
