title: First evidence of asymptomatic infection related to the Araucaria (Juquitiba-like) hantavirus.
abstract: Hantavirus pulmonary syndrome (HPS) is a severe disease, transmitted to humans by inhalation of virus-contaminated aerosols from rodent excreta. Epidemiological, clinical and laboratory data confirmed a fatal HPS case and an asymptomatic infection in a household contact, both caused by Araucaria hantavirus, which has previously been found only in patients with HPS. This is the first report of asymptomatic infection related to a pathogenic hantavirus genotype, highlighting the need for additional studies on characterisation of viral and genetic mechanisms associated with this disease.
