Argentina is the global focal point for Andes hantavirus. Cases concentrate in southwestern Patagonia (Chubut, Río Negro, Neuquén) and the northwestern provinces of Salta and Jujuy. Argentina is also the only country with confirmed person-to-person Andes transmission, including the 1996 Bariloche outbreak and several smaller household clusters since. The May 2026 MV Hondius cluster originated on a vessel that departed Ushuaia, and Argentine sequences are 99.7% identical to the MVH-2026 strain. Argentine national surveillance (Ministerio de Salud) reports 60–110 confirmed HPS cases annually with case fatality typically 25–40%; rural lodge workers, agricultural workers, and tourists who clean cabins are the highest-risk groups.
