According to a new study, an evolutionary shift around 2020 helped the bird flu virus adapt better to wild birds.

A cull of birds is to be carried out after an outbreak of avian flu was confirmed at a commercial poultry business. The government's Department for Environment, Food and Rural Affairs (Defra) said the "highly pathogenic" (HPAI) H5N1 illness had been found at premises near Dalton-in-Furness, south Cumbria.

Type A viruses are the most significant for human and animal health, and they are all descended from avian viruses. The flu A virus has two essential proteins in its envelope: haemagglutinin (H) and neuraminidase (N). There are 18 types of H and 11 types of N, which can be found in any combination: H1N1, H1N2, and so on up to H18N11.

A sixth case of bird flu in the space of a month has been confirmed in Suffolk. The Department for Environment, Food and Rural Affairs (Defra) said the H5N1 virus was found at a site near Claydon on Friday.
