Objective:

To provide updated surveillance data on cyclosporiasis cases in the United States.

Approach:
  • Surveillance Data Collection: The CDC has received reports of 1,645 laboratory-confirmed domestically acquired cases since May 1, 2026, and is aware of over 5,100 additional reports requiring further analysis as of July 13, 2026.
Key Findings:
  • 1,645 laboratory-confirmed domestically acquired cases reported from 34 states as of July 13, 2026.
  • 141 patients were hospitalized, with no reported deaths among domestically acquired cases.
  • 440 travel-associated cases reported from 35 states, with 20 hospitalizations and no deaths.
Interpretation:

The CDC anticipates an increase in reported case counts due to a 6-week lag in reporting and ongoing data collection.

Limitations:
  • Surveillance figures are preliminary and subject to change for the current reporting period.
  • The CDC's count includes only laboratory-confirmed cases.
Conclusion:

The CDC will issue surveillance updates more frequently this season due to the increase in reported cases.
