我们分析了在监测科罗拉多州啮齿类动物中 Sin Nombre 病毒传播和持久性的纵向研究中收集的双重捕获数据。我们的数据表明，多次捕获（在一个陷阱中捕获两只或更多啮齿动物）可能不是随机的，如之前的研究所示，而是潜在的、特定于物种的社会行为或凝聚力的结果。在我们捕获的成对啮齿动物中，大多数情况下，啮齿动物属于同一物种，是雄性，并且可以成对重新捕获。因此，对啮齿动物的双重捕获虽然不常见，但并不罕见，往往发生在某些物种中，并且似乎是非随机的群体觅食遭遇。这些人口和生态特征可能对汉坦病毒传播的研究有影响。
We analyzed dual-capture data collected during longitudinal studies monitoring transmission and persistence of Sin Nombre virus in rodents in Colorado. Our data indicate that multiple captures (two or more rodents captured in a single trap) may not be random, as indicated in previous studies, but rather the result of underlying, species-specific social behavior or cohesiveness. In the pairs we captured, most often, rodents were of the same species, were male, and could be recaptured as pairs. Therefore, dual captures of rodents, which are unusual but not rare, tend to occur among certain species, and appear to be nonrandom, group-foraging encounters. These demographic and ecologic characteristics may have implications for the study of the transmission of hantaviruses.
