About Hantatrack

A focused live tracker for the 2026 Andes virus outbreak. Transparent, source-cited, never authoritative.

On 1 April 2026 the Dutch cruise ship MV Hondius departed Ushuaia, Argentina. Within weeks, Andes virus cases linked to the voyage were being reported across multiple countries through different health authorities, in different languages, at different cadences. No single place was tracking the cluster live. Hantatrack exists to be that place — a focused, honest aggregator that links every count back to its primary source.

How Hantatrack works

Step 1
We aggregate

WHO Disease Outbreak News, CDC HAN, PAHO regional updates, ECDC threat reports, national ministries, and ReliefWeb — pulled continuously every six hours.

Step 2
We verify

Claims are classified by source tier. New countries or events flag for manual review; updates to known events apply automatically with the source URL preserved.

Step 3
You see the map

Live per-country pins, country-level confirmed and suspected overlays, an outbreak-day counter, and a one-click trail from every figure back to its primary source.

Map · Layers

What you see on the map

Hantatrack renders three independent visual layers, each tied to a different kind of evidence:

  • Cluster pins — countries with confirmed or suspected Andes virus cases. Filled red disc = at least one confirmed case; hollow yellow disc = suspected only. The three white dots inside the pin scale with the case count.
  • Transit pins — cases in motion (e.g. a passenger repatriated through a country without a domestic outbreak). Sky-blue hollow ring with a chevron.
  • Advisory pins — health authority warnings issued without a confirmed local case yet. Amber disc with an exclamation glyph.
  • Country overlays — red wash for countries with confirmed cases, yellow for suspected only. Toggleable from the bottom-left legend.
Data · Sources

Sources

  • WHO Disease Outbreak News (DON) — official international outbreak bulletins
  • CDC Health Alert Network (HAN) — U.S. clinical advisories for imported cases
  • PAHO — regional epidemiological updates for the Americas
  • ECDC — European communicable disease threat reports
  • National health ministries — Argentine MSAL, Chilean ISP, Dutch RIVM, and others as repatriated cases emerge
  • ReliefWeb — humanitarian aggregator surfacing news from multiple agencies
  • Major outlets — Reuters, AP, BBC, NYT — Tier 2 confirmation only, never primary

Every figure on the map links back to its primary source. We prefer incomplete transparency over false precision — when data is sparse, we show it explicitly rather than hiding it. See the methodology page for the full source-tier classification.

Disclaimers

What it is not

  • Not medical advice or a diagnostic tool
  • Not affiliated with WHO, CDC, PAHO, ECDC, RIVM, or any health authority
  • Not a substitute for official outbreak reports — always check the source links for primary information
  • Not a news service. We aggregate primary sources; we do not produce original journalism
