About this hantavirus map
A live, civilian-built tracker of the MV Hondius Andes hantavirus outbreak: confirmed cases, deaths, monitored regions, vessel position, and projected spread, all sourced from WHO, CDC, ECDC, and major news outlets.
HantaVirus Watcher is a live, civilian-built hantavirus map tracking the MV Hondius Andes hantavirus outbreak in real time. Every confirmed case, death, monitored region, vessel position, and projected spread zone on the map is sourced from a recurring scrape of WHO, CDC, ECDC, BBC, the Guardian, Reuters, AP, and a Google News index that pulls in NPR, NYT, Sky, and Al Jazeera coverage.
The page is the same one known across the web as the hanta virus map, the hanta virus watcher, and the MV Hondius outbreak tracker. There is no login, no paywall, and no advertising.
The MV Hondius hantavirus outbreak
The MV Hondius, operated by Oceanwide Expeditions, is the index vessel of an Andes hantavirus cluster that began in April 2026. Andes virus is the only hantavirus with documented person-to-person transmission, which is why the cluster has spread beyond its original passengers and crew into connected ports of call across the Atlantic and Europe. The map tracks each confirmed case by country and city, separates deaths from confirmed cases visually, and flags monitored regions where asymptomatic returnees are under observation.
Map layers
The map exposes four toggleable layers: Cases (confirmed and deaths, color-coded), Monitored (asymptomatic returnees), Route (the MV Hondius vessel track and last known port), and Predicted spread (model-derived risk zones based on travel network exposure). Layer state, theme, and map position persist across reloads.
Data freshness
A scheduled Cloudflare Worker re-scrapes the source feeds every six hours and re-runs an LLM extraction pass over each new article to add auto-extracted cases and monitored regions to the ledger. The vessel position and projected spread overlay recompute on every page load. The visible "Updated" badge in the header reflects the most recent scrape time.
Frequently asked questions
What is the hantavirus map on HantaVirus Watcher?
HantaVirus Watcher hosts a live hantavirus map that plots confirmed cases, deaths, monitored regions, the MV Hondius vessel route, and projected spread zones for the ongoing Andes hantavirus outbreak. Data is sourced from WHO, CDC, ECDC, BBC, Reuters, CNN, and other major outlets, then refreshed automatically.
What is the MV Hondius hantavirus outbreak?
The MV Hondius is an Oceanwide Expeditions vessel at the center of an Andes hantavirus cluster that began in April 2026. Andes virus is the only hantavirus with documented person-to-person transmission, which is why the outbreak has spread beyond initial passengers and crew.
How often is the hanta virus map updated?
The case ledger and news feed refresh every six hours from a Cloudflare Worker that scrapes WHO, CDC, ECDC, BBC, the Guardian, and Google News. The vessel position and predicted spread overlay update on every page load.
Is HantaVirus Watcher an official source?
No. HantaVirus Watcher is an independent civilian outbreak tracker that aggregates and visualizes information from official agencies (WHO, CDC, ECDC) and major news outlets. For medical guidance, consult your national health authority.
What is hantavirus?
Hantaviruses are a family of RNA viruses carried mainly by wild rodents. Most strains spread through inhaled aerosolized rodent urine, droppings, or saliva. The Andes strain at the center of the MV Hondius outbreak is unusual because it can transmit between humans. Severe disease can progress to hantavirus pulmonary syndrome (HPS) with respiratory failure.
Where is the MV Hondius right now?
The vessel route, current heading, and most recent port of call are shown live on the hantavirus map. As of May 2026 the ship departed Praia and is heading toward mainland Spain with 146 people aboard.
