Argentina halted first human-to-human hantavirus outbreak in 2018

In 2018, Argentina’s Epuyén faced the first major human-to-human Andes hantavirus outbreak, causing 34 infections and 11 deaths. Unlike typical rodent-borne spread, this strain transmitted via close contact. Authorities contained the crisis using aggressive contact tracing, isolation, and mandatory quarantines, strategies that remain vital lessons for global epidemiology.
