Interdepartmental Media Update – Hantavirus - May 10, 2026
Canada response context for Canadian passengers linked to the MV Hondius event.
Reviewed tracker
Hantavirus tracker for maps, cases, official alerts and rodent reservoirs
This tracker organizes reviewed public health sources into map layers for historical case context, official outbreak notices, reservoir ecology, and prevention guidance. It is not live infection tracking or exact local risk scoring.
Reviewed public health map
Live hantavirus map and case tracker
Track a reviewed hantavirus map snapshot with source-linked case summaries, Canada and US updates, selected official alerts, and reservoir regions. Not live local surveillance or county-precision case tracking.
Updated map snapshotOfficial-source review refreshed as new alerts and source candidates are checked.

Drag the map, pinch to zoom, or tap a colored marker. Use quick links if you are looking for a state, Canada, alerts, or sources.
Explore in 3 steps
Use the hantavirus tracker, check Canada or US context, then verify the source
This keeps the map useful without turning the homepage into a long report. Each shortcut opens a focused page for live-tracker intent, Canada or US context, sources, and limits.
1. What does this map marker mean?Compare reported cases, official alerts, and reservoir ecology before reading risk.2. Is there an official alert?Review selected WHO, ECDC, PAHO/WHO, CDC, and health department notices.3. Need regional context?Start with Florida, Canada, Washington, or the U.S. state map pages.
Search intent
What people usually mean by “hantavirus tracker”
Most users are trying to answer one of these questions. Each answer should stay tied to source type, geography level, review status, and limitations.
Where has hantavirus appeared?
Use the map to start with reviewed country, region, and state-level context, then open source links for official detail.
Does my state or region have historical cases?
The U.S. layer follows public state-level limitations and links to CDC and state health department records.
Are there recent official outbreak notices?
Official-source outbreak explainers summarize selected WHO, PAHO/WHO, ECDC, CDC, and state public health notices with limitations.
Which rodents and environments matter?
Reservoir ecology pages explain host-virus context without turning animal range into exact human risk.
How do I reduce risk while cleaning rodent contamination?
Prevention pages summarize CDC-style wet-cleaning guidance and escalation for heavy or workplace exposures.
How is this different from news signals or risk models?
Methodology pages separate reviewed case summaries, official alerts, reservoir ecology, and unreviewed news signals.
Layer model
The tracker separates data from signals
Reported case summaries: historical or agency-published records, not patient locations.
Official alerts: selected public health notices, not complete live surveillance.
Reservoir ecology: host and environment context, not proof of infected animals or human cases.
Prevention guidance: source-linked cleanup and rodent-exposure education, not medical diagnosis.
Internal index
Tracker index: sources, places and event records
These links connect the tracker to the reviewed human-facing data products behind the map: source pages, location pages, and event pages. Raw markdown records stay available through llms.txt, ai.txt, and openapi.json rather than the Google sitemap.
Where pages
Reviewed geography summaries, not live local risk maps.
Source notes
Official source pages with use and limitation notes.
Event records
Reviewed event/case records with citation-safe summaries.
