Abstract

Circulation of clade 2.3.4.4b highly pathogenic avian influenza H5Nx viruses has intensified in recent years, increasing epizootics and mammalian exposure. Cats, bridging wild and domestic environments, are key for studying cross-species transmission. To assess their exposure in France, we screened 728 outdoor cats (December 2023-January 2025). Seropositivity was 2.6% (19/728), with an estimated seroprevalence at 1.8%. Absence of hunting behaviour was a significant protective factor. These findings highlight high recent exposure and the need for targeted surveillance in cats.

猫作为暴露于H5Nx禽流感病毒的哺乳动物的哨兵：一项血清学研究，法国，2023年12月至2025年1月。

近年来，2.3.4.4b支高致病性禽流感H5Nx病毒的传播愈演愈烈，增加了动物流行病和哺乳动物暴露。猫作为野生环境和家养环境的桥梁，是研究跨物种传播的关键。为了评估它们在法国的暴露情况，我们筛选了728只户外猫（2023年12月至2025年1月）。血清阳性率为2.6%(19/728)，估计血清阳性率为1.8%。没有狩猎行为是一个重要的保护因素。这些发现强调了近期猫的高暴露率和有针对性监测的必要性。
