Trust layer
This page explains how source-backed data is maintained, which fields require review and why headlines are not used for case counts.
Official sources come first: WHO, ECDC, CDC and national health authorities. Operator and media sources provide context.
When sources disagree, this site keeps source dates visible and does not collapse categories into a single unsourced number.
Rule 1: WHO, ECDC, CDC and national public-health agencies come first for medical facts.
Rule 2: Operator and AIS sources provide vessel context; they do not override public-health case counts.
Rule 3: Media or signal sources can help discovery after review, but they are not direct case-count truth.
Rule 4: Every published medical number needs an as-of date and a visible source.
