Baby fox tests positive for BIRD FLU in Minnesota, officials reveal

A baby fox has tested positive for bird flu H5N1 in Minnesota, state officials revealed Wednesday, in the first case to be reported in a wild mammal in America.

The State’s Department of Natural Resources said the fox kit was found lying outside a fox den and being unable to use its back legs in Anoka County, near Minneapolis.

It was taken in by a family to be brought to a wildlife sanctuary the following morning, but it died overnight in their care.

Michelle Carstensen, the state’s wildlife health group lead, told DailyMail.com the fox had likely caught the virus after eating an infected wild water-fowl or domestic poultry that had the virus from a nearby farm.

The family that picked up the fox to take it to a nearby wildlife sanctuary are all being tested for bird flu themselves, Carstensen said. None are reporting symptoms of illness.

Following the case, foxes are now also being tested for bird flu in Wisconsin, Michigan, Iowa and New York, she said. Two were found to have caught bird flu in Ontario, Canada, last week.

The case underlines the risk of bird flu spreading from domestic poultry into other mammals, as well as humans.

Last month a prison inmate in Colorado became the first human to test positive for H5N1 after helping to euthanize an infected flock on a poultry farm. The individual was isolated with ‘very mild’ symptoms, and is thought to have since made a full recovery.

America is facing one of its worst ever bird flu outbreaks this year, with more than 24 million chickens and turkeys having already been culled — raising the price of meat and eggs nationwide.

SARS-CoV-2 — the virus that triggers Covid — may have initially jumped to humans from an animal species such as bats, although some theories suggest it was leaked from a lab in Wuhan, China.

Carstensen told DailyMail.com: ‘The fox was found with neurological symptoms, it was not able to walk well with its back legs.

‘The family intended to put it in a box because it was late evening, and in the morning take to a rehabilitation facility. But the animal died overnight.’

Asked where it could have caught the virus, she said: ‘The most common would be from what it was feeding on, and since it is a scavenger species there is a plethora of available dead things for it… so, most likely a water fowl carcass.

‘But it is possible that it could have been from a domestic poultry flock in the neighborhood. We’ve had a lot of raptor mortalities due to this.

‘It is very possible it could have even been in a local hen house.’

What is bird flu?

Also known as avian influenza, bird flu is an infectious disease of birds caused by a variant of the standard influenza A virus.

Bird flu is unique in that it can be transmitted directly from birds to humans.

There are 15 different strains of the virus. It is the H5N1 strain which is infecting humans and causing high death rates.

Humans can catch bird flu directly through close contact with live infected birds and those who work with infected chickens are most at risk.

She added: ‘I would remind people not to pick up sick or dead animals. It is much better to ring someone to come and help you rather than triggering a potential disease event.’

The department brought in the fox cub for routine testing for rabies because it had been in contact with humans.

But they also swabbed it for bird flu, after the cases that were declared in Canada. This swab came back positive.

An autopsy on the fox revealed it also had lesions on the brain, which were likely triggered by severe pneumonia.

State officials believe the animal caught the virus because it was young and had a still developing immune system, unlike older individuals.

Dr Joni Scheftel, a state veterinarian in Minnesota, said Wednesday: ‘Wild animals can sometimes transmit diseases to humans.

‘While we typically think of rabies or other well-known diseases as the primary concerns, this shows that there are other risks to keep in mind as well.

‘The best advice we have for Minnesotans is to avoid contact with wildlife that appears to be sick or injured and contact your healthcare provider if you are bitten or have close contact with wildlife.’

The state said it would now start testing all sick animals for bird flu alongside the typical diseases, such as rabies and canine distemper.

Minnesota has detected nearly 200 wild bird cases of bird flu to date in 19 species, primarily waterfowls and raptors.

Bird flu sparked concern in the late 2000s after it emerged that more than 60 percent of people who caught the virus died.

But scientists say a recent mutations in the virus mean there are now several new strains that are much less deadly to humans.

The US confirmed its first case of human bird flu in a man in Colorado last month, which was also the second case in the world. The only symptom reported was ‘fatigue for a few days’.

Colorado’s Department of Agriculture said the man — who has not been named — tested negative on repeat swabbing. But himself and ten others he worked with were all put into isolation as a precaution for fear of the virus being spread.

The first case of bird flu was detected in the UK in December 2021, in a man who was asymptomatic and shared his house with his poultry.

The individual recovered after only a mild illness but his birds all had to be culled.

This year’s bird flu outbreak is one of the worst on record with the strain able to infect all birds including chickens, ducks and even zoo animals.

Several American zoos have had to put their ostriches and even penguins on lockdown due to the disease — refusing them access to the outdoors for fear of them catching the virus.

Bird flu is spread by close contact or the droppings of migrating waterfowl – like geese, ducks and shorebirds – and is more often more likely to infect free-range chickens and indoor caged birds.

In 2015, the US had another bird flu epidemic that wiped out about 50 million chickens, costing the industry billions.

A virus that kills up to 50% of humans… but transmission is rare: Everything you need to know about bird flu

What is bird flu?

Bird flu, or avian flu, is an infectious type of influenza that spreads among bird species but can, on rare occasions, jump to human beings.

Like human influenza there are many strains of bird flu:

The current outbreak in birds in the US is H5N1, among other strains, which infected a prison inmate in Colorado.

Where has it been spotted in the US?

There are currently 15 states reporting cases of avian influenza among their poultry. These are Alaska, Colorado, Connecticut, Delaware, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan and Minnesota.

One case was also detected in an inmate who worked on a poultry farm in Colorado.

How deadly is the virus?

Fatality rates for bird flu in humans have been estimated to be as high as 50 per cent.

But because transmission to humans is so rare, around 500 bird flu deaths have been reported to the World Health Organization since 1997.

Is it transmissible from birds to humans?

Cases of bird-to-human transmission are rare and usually do not spread on human-to-human.

Bird flu is spread by close contact with an infected bird or the body of one.

This can include:

  • touching infected birds
  • touching droppings or bedding
  • killing or preparing infected poultry for cooking

Professor Ian Jones, a virologist at the University of Reading, England, said: ‘Transfer of avian flu to people is rare as it requires direct contact between an infected, usually dead, bird and the individual concerned.

‘It is a risk for the handlers who are charged with the disposal of carcasses after an outbreak but the virus does not spread generally and poses little threat.

‘It does not behave like the seasonal flu we are used to.

‘Despite the current heightened concern around viruses there is no risk to chicken meat or eggs and no need for public alarm.’

What are the symptoms?

Symptoms of bird flue usually take three to five days to appear with the most common being:

  • a very high temperature
  • or feeling hot or shivery
  • aching muscles
  • headache
  • a cough or shortness of breath
