Rapid literature review: Influenza A and Dairy Cattle

Share:
There is currently limited information available on the susceptibility of cattle to influenza A viruses (IAV). The susceptibility of cattle to avian IAVs in particular is not well understood and there are no published studies on cattle and the currently circulating H5N1 Eurasian lineage clade 2.3.4.4.b panzootic strain. However, throughout recent history, it has been noted that some cattle populations have shown signs of illness during outbreaks of influenza A in people (Sreenivasan et al., 2019) and a few research studies are available that investigate the susceptibility of cattle to human strains of IAVs in particular. Additionally, some experimental studies are available that investigate the susceptibility of cattle or related ruminants to other influenza A strains.
