Overview

Chile was one of the first countries to document Andes virus (1995) and has since developed one of the most robust hantavirus surveillance systems in Latin America. The southern regions (Los Lagos, Aysén, Magallanes) account for the majority of cases. Chile has also been a leader in ECMO therapy research for severe HPS cases.
