Spillover of highly pathogenic avian influenza H5N1 virus to dairy cattle

Share:
Nature has released an Accelerated Article Preview from Caserta et al. on the spillover of HPAI H5N1 from wild birds into dairy cattle. The manuscript reviews the epidemiological investigation of 9 farms in four states in the USA: Texas, New Mexico, Kansas and Ohio. One important finding was the transmission of H5N1 B.3.13 from a farm in Texas to a farm in Ohio after the transport of 42 apparently healthy lactating cows based on phylogenetic analysis.
