Andes virus incidence and lethality in Argentina have risen substantially. The 2025-2026 season has seen 101 cases, compared to 57 in the previous season, with lethality increasing to 32%. The Argentine Ministry of Health cited 41 confirmed cases in 2026, exceeding the epidemic threshold, with most occurring in Buenos Aires Province. The well-studied 2018-2019 Epuyén outbreak in Patagonia involved human-to-human transmission. Recent spread into more populated regions like Buenos Aires increases the risk of larger local and global outbreaks.
