Virus Hanta
Global hantavirus map methodology
How the map chooses sources, markers, colors and country status without pretending to be a live global case counter.
Derniere revision:
What the map is
The map is an editorial surveillance interface. It shows sourced events, prevention context and country-source status. Coordinates are regional centroids, country centroids or operational locations; they are never patient addresses.
Color describes marker severity or editorial category, not a precise country risk score. A country with limited data is labelled as limited rather than reviewed.
What the map is not
It is not a real-time global case database. It does not infer worldwide totals from search results. It does not let media reports update official counters alone.
Official case/death statistics require WHO, ECDC, CDC, PAHO, national public-health agencies or scientific sources.
How updates happen
Updates are append-only where possible: new entries include source URL, date, confidence, whether counters are affected and a justification. Old records stay available for audit rather than being silently rewritten.
This makes the site more useful for readers and safer for search engines and ad review.
