Corrections

The site corrects wrong case counts, misclassified case status, broken source links, route errors, publication-date mistakes, and medical statements that no longer match official guidance.

Outbreak counts can change as cases are confirmed, ruled out, reclassified, or added. The current dataset shows the latest official status split, while the timeline keeps historical source wording where useful.

To report an issue, include the page URL, the exact sentence or number, and the official source that supports the correction. Start with the methodology page to see the current source hierarchy.
