in short
- Hen flu is considered spreading quickly amongst migratory and home birds in Australia.
- Specialists warn the virus can stay for a big time period outdoors of a number animal.
The “devastating” H5N1 variant of avian influenza marked a grim milestone on Sunday as the primary confirmed case of transmission between chicken and mammal species was recorded, with consultants warning the worst is but to return.
An extended-nosed fur seal was confirmed to have died of the illness in coastal South Australia, with a second case being investigated in a seal in The Pages Conservation Park islands close to Kangaroo Island on Monday.
Earlier, Surroundings Minister Murray Watt mentioned the nation wanted to be “sensible” concerning the affect this sickness may have on native wildlife.
“We’re more likely to see mass mortalities of birds and mammals, and I do know that may be a very distressing factor for Australians to listen to,” Watt advised ABC tv.
Sean Dooley of the avian conservation group BirdLife Australia advised SBS Information that the virus might have an ecology-shifting affect.

“Potential extinction from the illness is feasible for some birds,” he mentioned.
“That is why we want an efficient response, the place we are able to, to mitigate the losses.
“We additionally want a large enhance within the sources that go into making certain resilient populations of as a lot of our species, or else we’ll be going through an actual ongoing disaster past the precise outbreak.”
How chicken flu spreads
Avian influenza, a flu-type virus, is airborne and contracted by birds and different mammals after they breathe or ingest it from an contaminated animal.
Robyn Alders, an honorary professor on the Growth Coverage Centre at Australian Nationwide College, advised SBS Information that the virus additionally survives outdoors of a number animal.
“Even if you cannot see a diseased carcass or a lifeless animal, it doesn’t suggest that the atmosphere there may be secure,” she mentioned.
“Significantly now that we’re beginning to see areas the place you have obtained bigger die-offs, the potential contamination in that space goes to be important.”
In cooler temperatures the place water is current, Alders mentioned there may be proof H5N1 can survive for days.
In areas the place the virus has but to reach, Dooley recommends individuals proceed spending time in nature and report something they think could possibly be chicken flu-related to the emergency animal illness hotline.
“That is nonetheless actually invaluable as a result of it might probably assist gradual the unfold as they take away these birds that are potential sources of an infection,” he mentioned.
Cats are notably inclined to the illness, and Alders recommends individuals maintain their cats indoors because the virus has a “50 per cent” mortality price for them.
‘We’re seeing gaps’
Hen flu vaccinations are underway in particular, appropriate populations in the mean time, however consultants query whether or not the federal government is satisfactorily ready.
Dooley mentioned the nation is in a stronger place now than it was just a few years in the past, however that authorities claims to have “completed all the pieces they might” are false.
“We’re seeing gaps,” he mentioned.
“When you speak to individuals on the bottom … it is actually hit or miss as as to if individuals have been skilled for this, or whether or not they have the gear, whether or not the PPE they want is filtering down.
“There’s lots of people panicking as a result of they do not know what to do they usually’re not resourced to do it.”
Agriculture Minister Julie Collins has mentioned the federal government is investigating whether or not chicken flu vaccine trials for marine mammals in North America could possibly be utilized in Australia — however that there’s “nothing commercially accessible” which might defend weak native seals.
In contrast to something we have seen earlier than
Whereas numerous avian influenza strains exist already in Australia, H5N1 is “so not like every other chicken flu virus we have handled”, Alders mentioned.
First detected in geese in China in 1996, the pressure has flared up previously however sometimes burnt out as a result of it is just too deadly.
The very fact the present lineage exists in any respect is right down to human exercise, Alders argued, notably the concentrated nature of poultry farming which creates enormous viral reservoirs.
“A virus that kills its host inside 48 hours — and that is what it does in chickens — should not survive,” she mentioned.
“I do not know the place this virus goes, however what I do know is that it was human exercise that, in some ways, facilitated this virus to proceed and to unfold.”
She mentioned it is “as much as us” to scale back and get rid of the virus.
“All people’s obtained to be a part of the dialogue about how we produce our meals, what requirements we count on, not solely when it comes to human welfare but additionally animal welfare, and actually working with agroecological cycles — not considering that we are able to reduce corners.
