Andes virus (ANDV) is a hantavirus found primarily in Argentina and Chile. It is the only hantavirus known to be capable of person-to-person transmission, in addition to the more common rodent-to-human transmission route.
Andes virus causes Hantavirus Pulmonary Syndrome (HPS), a serious respiratory illness. The reservoir host is the long-tailed pygmy rice rat (Oligoryzomys longicaudatus), found throughout Patagonia.
Patagonia, including southern Argentina and Chile, is the established endemic region for Andes virus. The Antarctic Peninsula region is reached via Patagonian ports such as Ushuaia.

The map displays publicly available events and geographic context. It does not track individual patients, private residences, or unconfirmed private movements.
Sources are monitored automatically every 30–60 minutes. When a source page changes, the update is queued for review. No data is published automatically — each item requires a human review step before it appears on the public map.
Every public datum includes: the source name, a confidence label, a last-checked timestamp, and a link to the original source where available.
Statistics such as confirmed case counts and risk levels are not published until they appear in official public health authority communications.
This map is based on publicly available sources only. It does not have access to non-public epidemiological data, clinical records, or government internal communications.
Media-reported items may contain inaccuracies or may be superseded by official statements. They are clearly labelled and should not be treated as confirmed facts.
Geographic locations are shown at the precision available from public sources. Many items are city-level or country-level only. The approximate route is for context, not navigation.
