Coverage & sourcesThe 2026 US cyclospora outbreak, the largest on record
Collected articles: every report in this story's record, counted once, in the week (Monday to Sunday, UTC) it was published; a report published on a Sunday evening in US Eastern time counts in the next week. Copies of the same wire story count as separate articles. This shows how much we collected, not how important a development was or whether it was independently confirmed. It covers this record only, not all news coverage. Our collection begins in October 2021.
