Infection of domestic cats with pandemic H1N1 influenza virus has recently been documented. We conducted a seroprevalence survey and found that 17 of 78 (21.8%) cats sampled during the 2009-2010 influenza season had antibody titers ≥40 against the novel H1N1 strain by hemagglutinin-inhibition assay, compared to only 1 of 39 (2.6%) sampled in 2008 prior to emergence of the pandemic (p = 0.006). Seroprevalance of seasonal H1N1 (41.9%) and H3N2 (25.6%) viruses was similarly high. These data reflecting past infection of household cats raise the possibility that they may act as a vector of influenza transmission within households.
最近有记录显示，家猫也感染了大流行 H1N1 流感病毒。我们进行了血清流行率调查，发现在 2009-2010 流感季节采集的 78 只猫中，有 17 只（21.8%）的血凝抑制抗体滴度≥40，而在大流行前的 2008 年采集的 39 只猫中，只有 1 只有抗体（2.6%）（p = 0.006）。季节性 H1N1（41.9%）和 H3N2（25.6%）病毒的血清流行率也同样很高。这些反映过去感染家养猫的数据表明，它们可能在家中充当流感传播的媒介。
