This is not a new illness, according to the CDC "So far this year, multiple states have reported an increase in cases compared to the same period in 2025." No deaths have been reported.

As of July 13, 2026:

  • Investigations to identify and confirm the sources of the outbreaks are ongoing.
  • U.S. cases reported to CDC: 1,645
    • The CDC surveillance updates do not include probable cases.
    • Since May 1, 2026, CDC has received reports of 1,645 confirmed domestic cases of cyclosporiasis and is aware of more than 5,100 cases that require further analysis to confirm the illness as domestically acquired cyclosporiasis. 
    • CDC is aware that states are likely to report higher case counts of cyclosporiasis than reflected in CDC data and is working closely with states to update numbers as additional cases are confirmed.
    • So far this year, multiple states have reported an increase in cases compared to the same period in 2025.  
    • Cases were reported by 34 states. These people became sick after eating food in the United States and did not report any travel during the 14 days before they got sick.
    • State data may include both probable and confirmed cases, which in turn is likely to reflect a higher case count than the CDC surveillance data because initial case reports have not yet been reported to CDC.
    • On a regular basis, CDC reports all laboratory-confirmed cases that are received from states.
  • Hospitalizations: 141
  • Deaths: 0
  • States reporting cases: 34
