MV Hondius Andes outbreak
Active Andes hantavirus outbreak linked to MV Hondius. ECDC reports 8 confirmed, 2 probable, 0 suspected, 1 inconclusive, and 3 deaths; shown as a route-level public-health event, not patient locations.
Public routes
6 exposure objectsRoute-level events only appear when public sources name them. This does not include passenger manifests, seat maps, or private medical details.
Andes virus is the hantavirus with documented rare person-to-person spread, so U.S. and Canadian response geography is shown only where official sources identify it.
Reported route context from Ushuaia through remote South Atlantic stops, Cabo Verde, and Tenerife. This is not a precise environmental exposure site.

Andes virus
What the site should know
Most hantavirus infections come from rodent excreta, but Andes virus is the only hantavirus known to spread person-to-person. Official guidance frames this as limited and associated with close or prolonged contact.
CDC guidance uses a 4-42 day incubation period. Early symptoms can include fever, myalgia, chills, gastrointestinal symptoms, and respiratory symptoms; severe disease can progress quickly.
There is no licensed specific antiviral treatment or vaccine for Andes virus. Care is supportive and can require ICU-level respiratory and hemodynamic support.
Andes virus is associated with South American rodent reservoirs, especially Oligoryzomys species in Argentina and Chile. Reservoir occurrence should be shown as ecological context, not human cases.
Precision
No precise patient pins
Public reporting is intentionally coarse. The interface treats small counts, rural events, and travel histories as sensitive.
Sources
Andes-specific first
ECDC, WHO, CDC, Argentina, Chile, and PAHO sit above news feeds in the confidence stack.
Transmission
Close-contact caveat
Andes virus has documented but limited person-to-person spread, usually tied to close or prolonged contact.
Event timeline

8 MayWHO confirms Andes virusWHO reported laboratory-confirmed Andes virus infections and described human-to-human transmission as the working hypothesis.
10 MayContact guidance publishedWHO and CDC guidance defined exposure and monitoring for potential Andes virus contacts from MV Hondius.
11-12 MayIreland repatriation confirmedHPSC confirmed Irish citizens from MV Hondius returned to Ireland for HSE-managed isolation; EU coordination named Ireland among evacuation operations using Tenerife South as the hub.

Provenance
What is live, curated, or planned
ECDC outbreak totals refresh from the source registry. Route, response-place, and endemic context entries are manually curated from linked sources.
Track confirmed, probable, suspected, inconclusive, non-case, death, hospitalized, and recovered fields with revision history.
Parse Argentina BEN and Chile MINSAL PDFs into region-level records with human review before publication.
Summarize CDC/WHO contact definitions, 42-day monitoring, and prevention language with direct citations.
Track public sequence metadata only when source licensing and privacy constraints are clear.
Use route, country, state, province, or facility-level public response markers instead of patient-location pins.
Public health UX
Prevention belongs beside the map
Keep Andes virus person-to-person language narrow: documented but limited, usually close or prolonged contact with a symptomatic person.
Separate rodent-exposure prevention from MV Hondius contact-management guidance so users do not generalize ship-specific quarantine rules to ordinary travel.
Lead with safe rodent cleanup: ventilate, wet/disinfect, avoid dry sweeping or vacuuming contaminated material, and use protective gear where guidance recommends it.
Attach source freshness and case-status labels to every count because active outbreak records can be reclassified after laboratory testing.
Data notes
What the map trusts
ECDC is the best current public source for MV Hondius Andes-virus status because it is updating the outbreak page daily during the active event.
WHO Disease Outbreak News gives the clearest case timeline, route context, case definitions, and risk framing for the international event.
CDC and WHO guidance should drive exposure, monitoring, and prevention language because Andes virus has documented but limited person-to-person spread.
Argentina and Chile are the priority endemic sources. PAHO is useful for reconciliation, but strain attribution must stay explicit.
ECDC totals refresh from the official outbreak page. Route, response-place, and endemic-context records are manually curated from linked sources and kept at coarse public-health precision.
