The rising fowl flu outbreakis being carefully monitored as if the virus mutates it may pose a “important menace” to human well being, a authorities adviser advised i.
Whereas the present threat to people is low, specialists are involved a mutation would enable avian flu to grow to be airborne and transmissible between individuals.
It is usually understood that the UK’s Animal and Plant Well being Company (APHA) has confirmed circumstances of fowl flu being transmitted to wild mammals, together with foxes and sea life similar to seals and dolphins in and across the UK, in addition to throughout Europe and within the US.
“Avian influenza represents a major ongoing menace to animal and human well being,” Professor Wendy Barclay, head of division of infectious illness at Imperial School London, advised i.
“We’re monitoring for indicators of the virus mutating and probably turning into airborne. That’s how pandemics occur.
“We’ve had 4 flu pandemics on this planet within the final 100 years, they usually have all mutated.
“It’s a roll of the cube if this present pressure mutates. The extra virus there may be the extra probably it’s to mutate.
“That’s one of many causes we’re involved as a result of, certainly, there may be lots of virus on the market within the wild.”
In June, the Authorities arrange a consortium of scientific establishments to battle in opposition to the worst outbreak of fowl flu ever seen, which has already led to the culling of virtually 4 million birds similar to chickens, geese and turkeys within the UK and nearly 100 million birds worldwide.
The group, generally known as FluMap, consists of APHA scientists, officers from the Division of Atmosphere, Meals & Rural Affairs (Defra), representatives from the Biotechnology and Organic Sciences Analysis Council, and impartial college scientists.
Professor Barclay, who’s a member of FluMap, says: “It’s vital to stress that in the meanwhile it’s very onerous for the virus to be transmitted to people.
“Well being officers concerned in culling birds take lots of precautions as they’ve a excessive publicity and catching it may be very dangerous.
“One of many issues that FluMap is trying out is whether or not or not this virus is slightly bit extra secure than earlier ones, and that may be why it has been hanging round for the reason that summer season and greater than we’ve seen earlier than.”
Official figures from the World Well being Organisation present that there have been 868 circumstances of human an infection with the H5N1 avian flu virus over the previous 20 years. The Authorities places the mortality price of individuals contracting fowl flu at 60 per cent, in comparison with a loss of life price for the height of Covid-19 of simply two per cent.

Professor Barclay stated: “If the virus underwent the mutations it must grow to be transmissible to people, then that 60 per cent fatality price may go down as a result of there’s a stability with viruses the place, as a way to grow to be transmissible, they’ve to vary their nature and normally meaning the fatality price goes down, nevertheless it doesn’t all the time.”
Just one individual is thought to have caught fowl flu within the UK. In December final yr, Alan Gosling of Buckfastleigh in Devon, contracted the illness from the rescue geese on his fowl sanctuary. Mr Gosling survived the illness and was given the all-clear in January.
A spokeswoman for the UK Well being Safety Company (UKHSA) stated: “The present proof means that the pressure of avian influenza at the moment circulating in birds doesn’t unfold simply to or between individuals.
“Nonetheless, viruses always evolve and that’s the reason UKHSA and APHA have monitoring in place to make sure we choose up any proof that the virus has unfold from birds to people.
“Though the proof means that the present pressure of avian influenza doesn’t unfold simply from birds to individuals, it’s important that folks don’t contact useless or sick birds.”
UKHSA is encouraging the general public to report findings of a single useless fowl of prey (together with owls), three or extra useless wild waterfowl (swans, geese or geese) or gulls, or 5 or extra useless birds of any species to their native authority.
Regardless of being onerous to catch from useless birds, well being officers coping with the culling of contaminated farmers’ inventory are taking excessive precautions, together with taking prophylactic Tamiflu and carrying private protecting gear earlier than attending outbreaks.
