Hantavirus Pulmonary Syndrome (HPS) is an emerging infectious disease of the Americas. Eight native rodent species have been identified as HPS virus reservoirs in Argentina. The aim of this work was to detect the orthohantavirus genotypes present in a rodent community that inhabits a zone where a fatal HPS case occurred within an endemic locality of Central Argentina. We captured 27 rodents with a trapping effort of 723 trap nights. We detected 14.3% of infected Akodon azarae with the Pergamino genotype. This result expands the known distribution of this orthohantavirus. Although the Pergamino genotype has not been associated with human cases, the information about its distribution is relevant for risk assessment against potential changes in the virus infectivity.

汉坦病毒肺综合征（HPS）是美洲新出现的传染病。阿根廷有 8 种本地啮齿动物已被确定为 HPS 病毒储存库。这项工作的目的是检测啮齿动物群落中存在的正汉坦病毒基因型，该啮齿动物群落居住在阿根廷中部流行地区发生致命 HPS 病例的地区。我们通过 723 个诱捕夜捕获了 27 只啮齿类动物。我们检测到 14.3% 的受感染Akodon azarae具有 Pergamino 基因型。这一结果扩大了该正汉坦病毒的已知分布。尽管 Pergamino 基因型尚未与人类病例相关，但有关其分布的信息与针对病毒感染性潜在变化的风险评估相关。
