Avian flu, or bird flu, affects birds across many species.
It generally doesn't infect people, but due to being a zoonotic virus, it can be transmitted through contact with infected birds.
According to the World Organisation for Animal Health, the virus is generally classified into two categories. There is low pathogenicity avian influenza (LPAI), which typically causes little or no clinical signs. Then there's high pathogenicity avian influenza (HPAI), which can cause severe clinical signs and possible high mortality rates.
Forbes reported that the farm where Emmanuel lives is a highly pathogenic strain, which has been impacting birds in the US since January 2022.
In the UK, the situation is particularly severe in East Anglia, where commercial and small-scale bird keepers are being hit, and mandatory housing measures for all poultry and captive birds in Norfolk, Suffolk and parts of Essex were introduced earlier in October.
The disease has also ripped through breeding colonies of seabirds, killing thousands in some sites and affecting threatened species from puffins to hen harriers.
