How to read a marker

Every marker on the map links to the original report and carries a confidence tier. Tap a marker to see the source, event date, and last-verified date.

Confirmed

Official public health agency confirmation.

Reported

Reported by a credible source, not yet officially confirmed.

Unverified

Uncertain sourcing — shown only with explicit caution label.

Speculative

Preliminary or anecdotal — context only, not a case claim.

Signal layers

Two automatic layers, ranked by source reliability:

  • Official agency (green) — CDC HAN / WHO DON advisories mentioning hantavirus. Confirmed by the agency itself.
  • News signal (blue) — media mentions indexed by GDELT. Reported, not confirmed cases.
  • All circles sit at a country centroid only, never a precise location.

3 signals with weak country metadata were left off the map and only appear on /sources.

How regions are tracked

Map markers appear only when a public health agency publishes a report with a verifiable source, date, and location. We do not add signals from social media, news summaries, or unverified claims.

Each marker shows: source name, publication date, last-verified date, confidence tier, and a direct link to the original report.

Stay updated

Data status: No verified live map points are currently published. When CDC, WHO, or state agencies publish reports with clear sourcing and location data, they will appear here. Until then, the map shows geography only — not an absence of disease anywhere. Not medical advice.
