“…Andes orthohantavirus (ANDV) is responsible for most HPS cases in the southern cone of South America, and two variants, ANDV‐ South and ANDV‐ BsAs, are capable of human‐to‐human transmission (Alonso et al, 2020; Ferres et al, 2007; Iglesias et al, 2016; Padula et al, 1998). Viruses of this species are hosted by rodents of the genus Oligoryzomys (Sub‐family Sigmodontinae), commonly known as ‘colilargos’ due to their long tail (Vadell, 2021).…”

“…Hantavirus pulmonary syndrome (HPS) is a zoonotic emerging infectious disease characterized by a rapid onset of pulmonary oedema followed by respiratory failure and cardiogenic shock (MacNeil et al, 2011). Though HPS has a relatively low incidence, its fatality rate is high, reaching almost 40% in some areas (Vadell, 2021). It is caused by New World orthohantaviruses (family Hantaviridae , Subfamily Mammantavinirae , Genus Orthohantavirus ; Laenen et al, 2019) which are hosted by rodents of the family Cricetidae.…”

Hantavirus pulmonary syndrome (HPS) is a zoonotic emerging infectious disease caused by New World orthohantaviruses (family Hantaviridae) hosted by rodents of the family Cricetidae. In Argentina, one of its main hosts is the sigmodontine rodent Oligoryzomys flavescens, a widely distributed mouse of the Pampas, Delta and Espinal ecoregions of central‐east Argentina. Because the abundance of the reservoir and its proportion in the rodent community affects both virus prevalence and human exposure risk, its estimation throughout its known geographical distribution is of key importance for the design of public health strategies to prevent HPS. The aim of this study was therefore to model the relative abundance of O. flavescens in most of the Pampas ecoregion within Buenos Aires Province, Argentina, where hantavirus pulmonary syndrome is endemic. To do this we used owl‐pellet samples collected between 2006 and 2008 from 51 sites distributed throughout most of Buenos Aires province. Mammalian prey in each pellet was identified to the lowest possible taxonomic level by examination of the skulls, dentaries and molars. We modelled the frequency of O. flavescens found in each sample as a function of climatic, environmental, and topographic data of each site. The two best models were applied to a Geo referential Information System to build maps of estimated frequency (as a proxy of relative abundance) within Buenos Aires province. Estimated relative abundance of O. flavescens in Buenos Aires province was significantly associated with annual mean temperature, annual precipitation and presence of freshwater bodies, and varied among sub‐regions, with the Inland and Rolling Pampas being the regions with highest frequencies. Knowing in which areas O. flavescens abundance is expected to be higher can be used to concentrate limited sanitary efforts in those areas that are most needed in order to reduce transmission and increase detection.

“…Orthohantavirus is a genus of globally distributed RNA viruses in the family Hantaviridae . In the Americas, the viruses are hosted by native rodent species within the Cricetidae family ( 1 ). Although not all orthohantaviruses cause disease in humans, some genotypes are etiologic agents of hantavirus cardiopulmonary syndrome (HCPS), a serious emerging disease ( 1 ).…”
