Cyclosporiasis Cases per Week

Cumulative cases compared to new cases per week over time from July 23, 2026 to now.

Our research team reviews each state health department's website to determine the total number of cyclosporiasis cases (confirmed and probable) reported in the last week and for the year. It is important to note that some health departments include cases for the entirety of 2026 and some begin their cases counts May 1, 2026. Local health departments and local news websites are utilized if information is not available at the state level. These sources are reviewed regularly and case numbers are updated in our map Thursdays by 4PM ET. Please note that health departments update their own websites on different days and at different frequencies, so our case counts may differ from what is currently reflected on their websites. Delays in reporting cases may also lead to changes in the previous week's case counts.
