Hantavirus pulmonary syndrome is an emerging infectious disease caused by viruses of the genus Orthohantavirus. The rodent Oligoryzomys flavescens is distributed along four countries of South America. In Argentina, O. flavescens acts as a reservoir of three genotypes of ANDV orthohantavirus. The aims of this work were to estimate home range size and movements-with spool-and-line and radiotelemetry-of infected and non-infected O. flavescens in order to understand the spread and transmission of the virus. O. flavescens use a wide area to satisfice its requirements, reaching a home range of 1.82 ha during spring. Orthohantavirus infection did not change the behaviour of individuals. We observed a great overlapping in the home range of infected and non-infected individuals resulting in a high probability of virus dispersion on rodent population. These results show that human health risks could be high on island environments and knowledge about the movement ecology of O. flavescens provides useful information on prevention.
汉坦病毒肺综合征是一种由正布尼亚病毒属病毒引起的新发传染病。金黄姬鼠分布于南美洲的四个国家。在阿根廷，金黄姬鼠是三种基因型的ANDV 正布尼亚病毒的储存宿主。本研究的目的是估计受感染和未受感染的金黄姬鼠的家域大小和运动范围（使用线轮和无线电遥测技术），以了解病毒的传播和传播。金黄姬鼠使用广泛的区域来满足其需求，在春季达到 1.82 公顷的家域范围。正布尼亚病毒感染并没有改变个体的行为。我们观察到受感染和未受感染个体的家域有很大的重叠，导致病毒在鼠群中的传播概率很高。这些结果表明，岛屿环境中的人类健康风险可能很高，对金黄姬鼠运动生态学的了解为预防提供了有用的信息。
