Each entry is dated by the survey it was written in (the CDC re-sent the releases with survey dates in 2025); click a date to see that survey response. The CDC cut some text off at about 250 characters: symptoms in every release, and the other two fields in releases 9-12. Those entries are marked "cut off by CDC".
