Hantavirus in Brazil BR

Brazil reports HPS cases from multiple endemic regions, with several distinct hantaviruses circulating — Araraquara virus, Juquitiba virus, Castelo dos Sonhos virus, and others. Case-fatality rates are high. Risk concentrates in the central and southeastern states (São Paulo, Minas Gerais, Paraná, Santa Catarina) where agricultural expansion into Cerrado and Atlantic Forest habitats increases rodent contact.
