The UK government has announced the relaxation of mandatory housing restrictions for poultry and captive birds, effective from April 18, as the risk of bird flu infection eases following a severe outbreak over the past two years. This outbreak, caused by the 2.3.4.4b clade of the H5N1 serotype, marked the UK's most widespread and prolonged bird flu episode in modern times, impacting over 300 poultry farms and leading to the culling of more than 50 million birds across 37 countries. This strain of bird flu has shown unprecedented affects on wild bird species, with over 60 species affected in the UK, and has also posed a threat to mammals through direct contact with infected birds or their feces.
