One person in the South West of England has confirmed bird flu, the UK Health Security Agency (UKHSA) has said.

The risk to the wider public continues to be very low, the UKHSA said, but urged people not touch sick or dead birds.

In a statement, the health protection body said: “Bird to human transmission of avian flu is very rare and has only occurred a small number of times in the UK previously.

“The person acquired the infection from very close, regular contact with a large number of infected birds, which they kept in and around their home over a prolonged period of time.

“All contacts of the individual, including those who visited the premises, have been traced and there is no evidence of onward spread of the infection to anyone else. The individual is currently well and self-isolating.”

The UK has recently seen a large number of bird flu outbreaks among animals, with the UK’s Chief Veterinary Officer, Christine Middlemiss, issuing warnings to bird owners over hygiene.

On December 21, she said the UK faced its largest ever outbreak of bird flu with more than 60 cases confirmed across the country since the start of November.

Some strains of bird flu can pass from birds to people, but this is extremely rare, according to the UKHSA.

It usually requires close contact with an infected bird, so the risk to humans is generally considered very low.

Human-to-human transmission of bird flu is also very rare, the organisation said.

The case was detected after the Animal and Plant health Agency (APHA) identified an outbreak of the H5N1 strain of bird flu in a flock of birds.

The infected birds have all been culled.

As a precaution, the UKHSA swabbed the person involved and detected low levels of flu.

Further lab analysis showed that the virus was the ‘H5’ type found in birds.

The UKHSA said that, at this point, it has not been possible to confirm that this is a H5N1 infection (the strain that is currently circulating in birds in the UK).

But the UKHSA has notified the World Health Organisation (WHO) as a precaution.

It said this is the first human case of this strain in the UK, although there have been cases elsewhere globally.

Professor Isabel Oliver, chief scientific officer at the UKHSA, said: “While the risk of avian flu to the general public is very low, we know that some strains do have the potential to spread to humans and that’s why we have robust systems in place to detect these early and take action.

“Currently there is no evidence that this strain detected in the UK can spread from person to person, but we know that viruses evolve all the time and we continue to monitor the situation closely.

“We have followed up all of this individual’s contacts and have not identified any onward spread.”

Ms Middlemiss said: “While avian influenza is highly contagious in birds, this is a very rare event and is very specific to the circumstances on this premises.

“We took swift action to limit the spread of the disease at the site in question, all infected birds have been humanely culled, and cleansing and disinfection of the premises is underway.

“This is a reminder that stringent cleanliness when keeping animals is important.

“We are seeing a growing number of cases in birds on both commercial farms and in backyard flocks across the country. Implementing scrupulous biosecurity measures will help keep your birds safe.”

For contacts of an infected person who have the highest risk, the UKHSA contacts them daily to see if they have developed symptoms.

People are also offered anti-viral treatment after exposure to infected birds to stop the virus reproducing in their body.

Swabs are also carried out on people even if they do not have symptoms.
