CDC adds four states to the cyclospora map, bringing total U.S. cases near 7,000 with 2,500 new infections reported this week.

The United States saw 2,500 new cyclospora infections reported this week, pushing the national total to nearly 7,000 cases across almost every state, as the CDC updates its outbreak map [1]. The surge underscores continued public‑health pressure on fresh‑produce safety during the peak summer season.  

| At a glance | |
|---|---|
| New cases (week) | 2,500 |
| Total U.S. cases | ~7,000 |
| States added | Idaho, plus three others |
| Primary suspected source | Shredded iceberg lettuce (Taylor Farms) |

## Outbreak expansion and source focus  
Idaho became the latest state to confirm a cyclospora infection, marking the fourth addition to the CDC’s map in recent days [1]. The CDC’s surveillance season runs through Aug. 31, and officials expect case numbers to stay elevated until then, reflecting the typical summer peak for the parasite [1]. While no single food item has been definitively identified nationwide, investigators in Michigan have pointed to shredded iceberg lettuce supplied by Taylor Farms as the most likely source for the large Midwest cluster, linking it to Taco Bell locations in several states [2]. The FDA and CDC continue to trace the lettuce’s distribution, which has reached 27 states and includes shipments to major retailers such as Walmart and Jack in the Box [2].

## Geographic spread and hospitalization data  
The outbreak now involves 45 states with at least one domestically acquired case, though the highest counts remain in Michigan (over 10,000 reported) and Ohio (2,574 cases) [2]. Hospitalizations have risen, with at least 98 nationwide and over 160 in Michigan alone, though no deaths have been recorded [2]. The CDC notes that the true infection count is likely higher than official reports, as many individuals recover without seeking medical care [1].

## Public‑health response and guidance  
Health officials advise consumers to scrub firm produce, discard bruised sections, and sanitize preparation surfaces to reduce infection risk [1]. Specific advisories target shredded iceberg lettuce from Taylor Farms, recommending avoidance of any such product in states linked to the outbreak, including Indiana, Kentucky, Michigan, Ohio, and West Virginia [2]. The recall and removal of the lettuce from Taco Bell’s supply chain aim to curb further spread while investigations continue.

## What to watch  
- **Case trends**: Weekly CDC updates on new infections and state additions, especially as the surveillance window closes on Aug. 31.  
- **Product recalls**: Any expansion of the Taylor Farms lettuce recall to additional retailers or states.  
- **Hospitalization reports**: Increases in hospital admissions could signal a worsening outbreak severity.  

The ongoing cyclospora surge highlights the challenges of tracing foodborne parasites in a fragmented supply chain, and the effectiveness of current recalls will be a key factor in limiting the outbreak’s summer peak.
