New Mutations Help H5N1 Bird Flu Virus Infect Cows, Not People
Recent research highlights the ongoing evolution of the H5N1 bird flu virus within livestock populations. The study reveals specific genetic changes that have enabled the virus to successfully infect cattle. Crucially, these mutations do not appear to facilitate human infection, indicating a current divergence in the virus's adaptation capabilities between species. This development offers insights into how H5N1 is adapting in its animal hosts and what this might signify for the future of human health in relation to this avian influenza strain.
