Bird 'Flu: Ewe Too?


 After contracting the H5N1 variant of bird 'flu, many Mammals have subsequently died . Now, the first case of this viral infection has been recorded in a female sheep (Ovis aries)' The animal concerned was based on a farm in northern England. Birds on that farm had contracted bird 'flu (probably from wild birds). None of the other sheep in the flock (including the ewe's own lambs), had antibodies to the virus (https://www.reuters.com/world/uk/uk-detects-bird-flu-sheep-first-time-2025-03-24/). Many of the wild Mammals, contracting this virus, have been carnivores, who may have eaten dead birds. Herbivores, including US dairy cattle are, however, becoming infected by H5N1. The addition of sheep, suggests the pandemic risk to humans is growing.
