Rodent trapping was conducted at seven hantavirus pulmonary syndrome (HPS) case sites from June 1993 to March 1994 during the HPS outbreak in the southwestern United States. To determine if there were changes in the rodent population or the hantavirus seroprevalence in rodents since the HPS outbreak, rodents were trapped at the same sites three years later using the same trapping protocol. The trap success decreased from the numbers trapped during the outbreak, however, the number of Peromyscus, as a percentage of the total rodents captured, did not noticeably decrease. In addition, the seroprevalence of hantavirus antibodies in Peromyscus decreased significantly (P < 0.0001).
1993年6月至1994年3月，在美国西南部汉坦病毒肺综合征（HPS）疫情期间，在7个HPS病例地点进行了啮齿动物诱捕。为了确定自HPS疫情爆发以来啮齿动物种群或啮齿动物中汉坦病毒血清阳性率是否发生变化，三年后在相同地点使用相同的诱捕方案诱捕啮齿动物。诱捕成功率比疫情期间诱捕的数量有所下降，然而，作为捕获的啮齿动物总数的百分比，白足鼠的数量没有明显减少。此外，白足鼠中汉坦病毒抗体的血清阳性率显著下降（P < 0.0001）。
