Hunting-training #dogs & companion dogs in #Netherlands are frequently exposed to highly pathogenic avian #influenza #H5 & human #H1N1 virus, 2021–2023
Highlights • High seropositivity in dogs to highly pathogenic avian influenza (HPAI) H5 virus in the Netherlands during HPAI H5 endemicity in wild birds. • HPAI H5-seropositivity higher in hunting -training dogs than companion dogs. • HPAI H5-seropositivity in hunting-training dogs associated with recent bird contact in/near water. • High seropositivity in dogs to human H1N1pdm2009 influenza A virus (IAV). • H1N1pdm2009-seropositivity higher in companion dogs than hunting-training dogs. Abstract Dogs are susceptible to the currently circulating highly pathogenic avian influenza (HPAI) H5 and human H1N1pdm2009 (pandemic H1N1) viruses, yet little is known about the extent to which dogs are exposed to both these viruses. Here we investigated HPAI H5 and human H1N1pdm2009 virus exposure in domestic dogs–including dogs that participated in hunting-training– and investigated lifestyle factors associated with HPAI H5 virus exposure. We screened sera from 538...
