Purpose
Hantavirus Map provides a geographic view of the 2026 Andes hantavirus outbreak linked to the cruise ship MV Hondius. The site is not operated by, endorsed by or affiliated with WHO, CDC, ECDC or any national health authority. Its purpose is to present publicly available surveillance data and verified reporting in a clear, map-centered format during a fast-moving international health event.
Where the data comes from
How map markers are placed
Each marker on the map represents a location where a confirmed case, probable case, death or monitoring programme has been officially reported. Markers are placed at the national level (capital city coordinates) unless a more specific location is known (such as the ship's position or the Ushuaia departure point). Marker colours follow a consistent scheme: bright red for deaths, red for confirmed cases, dark red for suspected or probable cases, green for active monitoring with no confirmed cases, and blue for the ship position.
Update process
The backend service polls WHO and CDC pages every 30 minutes. Numerical data (case counts, deaths) uses a highest-reported-value merge — if WHO reports 9 confirmed and CDC reports 8, the map shows 9, because case counts in an active outbreak only move upward. Timeline events and news items are added manually after verification against at least two independent sources (typically one health authority and one wire service). The "updated" timestamp reflects the last successful data synchronisation.
What this site cannot do
This is not a diagnostic tool, a substitute for medical advice, or an official public health resource. Data is compiled from public sources and is subject to reporting delays, translation differences and revision by the originating agencies. If you need to make a health decision — whether to seek testing, whether to travel, whether to isolate — contact your national health authority directly or call your local emergency number.
