Crowdsourced Cyclospora Watch

Feeling sick or have a confirmed case of cyclospora? Submit your report here

36 responses collected so far. This is a self-reported, crowdsourced tracker built to try to spot patterns in the current multistate cyclospora outbreak — not an official CDC or state health department investigation. There is no control group, so results below are proportional reporting among people who got sick, not proof of cause. Treat this as “worth watching,” not “confirmed.”

Top produce leads

Sorted by signal ratio — how much more often cases report eating this compared to how often people eat it in an ordinary two-week period. A ratio above 1 means it’s showing up more than you’d expect from typical diets.

CI columns are a 95% confidence interval — small sample sizes mean wide ranges. If the “Ratio CI low” column is still above 1, that’s a stronger lead than the point estimate alone.

Cases by state

This is a representation of the cases that have been self-reported in this survey. For the official case count, please refer to the CDC or your relevant state/local health department.

Stores & restaurants mentioned

Reported symptom duration

Cyclospora illness tends to run longer than most foodborne bugs (often weeks, sometimes relapsing). Short-duration reports are more likely something else.

Epi curve

Reddit thread parsed sources

This is a hand-compiled tally of food/restaurant mentions from Reddit threads, kept separate from the statistical analysis above since it doesn’t have the per-person structure needed for the confidence intervals or signal ratios. Read as “what’s been mentioned together,” not as a statistical finding.

How to read this page: a high signal ratio means the food is reported by sick people more than you’d expect from normal eating habits — that’s a lead worth watching, not a verdict. Small numbers (a food only 2-3 people mentioned) are noisy and easy to over-read. If something looks concerning and consistent, the right next step is reporting it to your local or state health department, who can do formal case-control interviews and trace product lots — this page can’t do that part.
