Bird flu (avian influenza): latest situation in England

From:
Department for Environment, Food & Rural Affairs and Animal and Plant Health Agency

Latest situation

Take action to prevent bird flu and stop it spreading. Be vigilant for signs of disease and report it to keep your birds safe.

Highly pathogenic avian influenza (HPAI) H5N5 has been detected in a number of wild birds in Great Britain this autumn. This includes the first reported wild bird mass mortality of the season associated with an HPAI finding.

The risk level of HPAI H5 in wild birds has increased from low to medium.

The risk level in poultry remains assessed as:
  • low where there is suboptimal or poor biosecurity
  • very low where good biosecurity is consistently applied at all times
While findings of HPAI in wild birds during recent years have been dominated by the H5N1 virus strain, the finding of HPAI H5N5 was likely this season and follows previous findings in Great Britain and recent detections of the strain in continental Europe.

While the UK does not currently have outbreaks of HPAI in poultry or other captive birds, keepers must remain vigilant and practise stringent biosecurity to protect the health and welfare of their birds. Find out how to protect your birds in our biosecurity guidance.

New registration requirements for bird keepers in Great Britain


On 19 March the government announced new measures to help protect the poultry sector from bird flu.

All bird flu cases and disease control zones


There are no current disease control zones in England.

The UK has self-declared zonal freedom from highly pathogenic avian influenza for Great Britain with effect from 29 March 2024 and in Northern Ireland from 31 March 2023. This is in line with World Organisation for Animal Health (WOAH) rules.

The last outbreak of HPAI in poultry and other captive birds in the UK occurred between 26 October 2021 and 29 March 2024.

The last cases were confirmed in:
  • England on 14 February 2024
  • Scotland on 22 November 2023
  • Wales on 27 April 2023
  • Northern Ireland on 16 October 2022

Seabird recovery slow at Shetland National Nature Reserves

16 December 2024

Numbers of great skua or bonxies at Shetland National Nature Reserves (NNRs) increased slightly this year but remain significantly below pre-avian flu levels.

A full census of the species, for which Shetland is a global stronghold, was carried out at NatureScot’s Hermaness and Noss NNRs this year to see how populations are faring after the devastating impact of the virus in 2022.

At Hermaness 220 breeding pairs were counted, a small increase from 208 in 2023 but still down a huge 77% on the 955 counted in 2018, the last full census before the outbreak.

Meanwhile the Noss count found 80 pairs of bonxie, up from 69 in 2023 but a drastic decline of 83% from 476 in 2018.

While a full count was not carried out this year, numbers of gannets, a species that was also hit badly by bird flu, were observed to be slightly up at Hermaness in 2024. However, again it is estimated that the previous upward trend in this species has been set back by 20 years at the reserve. Gannets reached 29,562 nests in 2021 pre-bird flu but were down to 18,739 nests at the last census in 2023.

Thankfully there was only one positive case of avian flu in seabird populations at the reserves during the breeding season. NNR staff are remaining vigilant however, after a small number of positive tests in great black-backed gull and bonxie at the end of the season. These have been confirmed as the H5N5 strain of avian flu, in contrast to the H5N1 strain of 2022.

Juan Brown, NatureScot Operations Officer, said: “This year’s seabird census reveals the ongoing impact of the avian flu outbreak in 2022 and the painfully slow recovery of these populations which are likely to take years, if not decades, to reach pre-outbreak levels once again.

“In contrast to recent years, the small number of positive avian flu tests we have had this year have all been the H5N5 strain of the virus, rather than H5N1. While we don’t yet know what the impact of H5N5 will be on wild bird populations, we are keeping a close eye on the situation and encourage people to report all sightings of sick or dead birds using the GB online reporting system. Sightings will help us track the spread of the virus and assess impacts on wild bird populations.”

In what was generally a poor breeding season for seabirds overall, there was better news for storm petrels at Noss. A total of 35 birds responded to call recordings played next to potential nest holes during a survey this year - the highest since this secretive seabird was found breeding on Noss in 2008. As only a proportion of birds respond, the population will be significantly bigger.

In other good news, Hermaness welcomed its highest visitor numbers on record, with more than 13,000 people enjoying the reserve, including local school groups and guided walks. This continues the upwards trend over the past four years, which have also seen new visitor facilities installed.

At Noss visitor numbers returned to normal levels for the first time since Covid, despite the ferry not running on an unprecedented number of days due to bad weather. Visitors who made the crossing were able to enjoy the newly completed interpretation panels at the Visitor Centre.
