Overview
- Mar del Plata recorded its first hantavirus death, a 33-year-old resident of Sierra de los Padres with rural exposures such as hunting and taxidermy, with the diagnosis ratified by the Instituto Malbrán.
- San Andrés de Giles confirmed the death of 14-year-old Rodrigo Morínigo, whose diagnosis was verified on January 2 before he died on January 3 in Pergamino.
- National surveillance logged 77 confirmed cases and 23 deaths in 2025, a 29.8% case-fatality rate, and 43 cases have already been notified in the current season.
- Roughly 70% of last year’s cases were in the central region, including Buenos Aires province, where authorities have activated protocols, traced contacts, and carried out environmental controls.
- Health guidance urges ventilating enclosed spaces, sealing gaps, and cleaning rodent droppings with diluted bleach, as infection most often follows inhalation of particles from wild rodent excreta.
