Highly pathogenic avian influenza (HPAI) H5 virus exposure in domestic cats and rural stray cats, the Netherlands, October 2020 to June 2023.
BackgroundHighly pathogenic avian influenza (HPAI) H5Nx and human H1N1pdm2009 influenza viruses can infect cats. Infections in cats may result in viral adaptations or recombinant viruses, which may facilitate zoonotic transfer.AimWe aimed to investigate the presence of HPAI H5 clade 2.3.4.4 and H1 influenza viruses and antibodies to these viruses in domestic and rural stray cats in the Netherlands and factors associated with exposure.MethodsSera from stray and domestic cats, sampled 2020-2023, were analysed by ELISA and confirmed by hemagglutination inhibition assay (HAI) and pharyngeal swabs and lung tissue for influenza A virus by RT-qPCR.ResultsIn 701 stray cats, 83 (11.8%; 95% confidence interval (CI): 9.5-14.5) sera were positive for HPAI H5 and 65 findings were confirmed. In HAI, two sera were positive for both HPAI H5 and H1. In 871 domestic cats, four (0.46%; 95% CI: 0.13-1.2) sera were HPAI H5 positive and none were confirmed but 40 (4.6%; 95% CI: 3.3-6.2) sera were seropositive for H1 and 26 were confirmed. Stray cats living in nature reserves (odds ratio (OR) = 5.4; 95% CI: 1.5-20.1) and older cats (OR = 3.8; 95% CI: 2.7-7.1) were more likely to be HPAI H5 seropositive. No influenza A virus was detected in 230 cats.ConclusionThe higher HPAI H5 seroprevalence in stray cats compared with domestic cats suggests more frequent viral exposure, most likely due to foraging on wild birds. In contrast, exposure to H1 was more common in domestic cats compared with stray cats.

Eurosurveillance is a European peer-reviewed journal focusing on the epidemiology, surveillance, prevention, and control of communicable diseases relevant to Europe.It is a weekly online journal, with 50 issues per year published on Thursdays. The journal includes short rapid communications, in-depth research articles, surveillance reports, reviews, and perspective papers. It excels in timely publication of authoritative papers on ongoing outbreaks or other public health events. Under special circumstances when current events need to be urgently communicated to readers for rapid public health action, e-alerts can be released outside of the regular publishing schedule.
