Viral TikTok star Emmanuel – an emu who gained an enormous on-line following because of movies shared by his proprietor at Knuckle Bump Farms in Florida – has reportedly fallen sick with avian influenza.
Farm proprietor Taylor Blake wrote on Twitter that wild geese introduced avian influenza to the farm, with many birds having since died.
We put our brains collectively and constructed Emmanuel a sling in order that we will begin bodily remedy with him, within the hopes that he’ll regain perform of his proper foot/leg. We have now been tweaking and perfecting it during the last 48hrs. pic.twitter.com/rnltpoyzAE

As a big outbreak sweeps poultry farms throughout the US and the UK, many individuals at the moment are asking: what precisely is avian influenza, and what do I must know? What’s avian influenza?
Avian influenza is a illness brought on by an influenza A virus, affecting birds throughout many species.
It might probably have important penalties for the poultry business, on account of its potential affect on chook well being, manufacturing and even worldwide commerce.
Though avian influenza doesn’t often infect folks, it’s thought of a zoonotic virus. Meaning it may be transmitted to people by contact with contaminated birds, and sporadic instances have been seen when outbreaks occur in poultry.
Some avian influenza viruses are extra pathogenic than others. Pathogenic means disease-causing, so if extremely pathogenic avian influenza will get right into a poultry farm, it could trigger sudden and important mortality.

It has been reported the outbreak underway on the farm the place Emmanuel lives is a extremely pathogenic pressure, which has been affecting poultry and wild birds within the US since January 2022.
Even low pathogenic strains could make birds unwell and trigger them to put fewer eggs.
Avian influenza infections in people may cause a spread of medical signs, from delicate higher respiratory signs to extreme pneumonia.
Some strains of avian influenza, similar to extremely pathogenic H5N1 and H7N9, may cause important illness in people, and in some situations even dying.
Advisable normal remedy for people is with antiviral medicine, and can depend upon particular person circumstances and severity of the signs.
In home birds, the almost definitely path of an infection is thru contact with contaminated wild birds. This might be direct contact or contact by water contaminated with wild chook droppings.
Typically, an outbreak of avian influenza on a poultry farm means many birds need to be culled in an effort to cease the unfold.
Is there any avian flu in Australia?
Australia is classed by the World Organisation for Animal Well being as freed from avian influenza within the home chook inhabitants. Nevertheless, we do at the moment have a low-level circulation of low pathogenic influenza viruses amongst wild birds.
We have now had a number of low and extremely pathogenic avian influenza outbreaks in home poultry in Australia earlier than, with the newest one affecting farms in Victoria. Many birds have been culled to eradicate the illness and in all instances eradication was profitable.
Not one of the viruses inflicting these outbreaks in Australia have prompted illness in people. Nevertheless, it’s important that we use hygienic practices and biosecurity when working with poultry.
We at the moment should not have H5N1 in Australia; waterfowl, the chook species almost definitely to hold this virus, don’t migrate to Australia. As well as, Australia has very strict biosecurity measures to stop illness introduction by imports. Due to this fact, the chance of introduction of this pressure into the nation may be very low.
Most measures aimed toward lowering the chance of avian influenza outbreaks in poultry in Australia have targeted on lowering contact between wild birds and farmed birds.
Meaning limiting the entry wild birds can get to farms, in addition to defending and treating water sources.
Prior to now decade, we have now seen a rise within the variety of home outbreaks in Australia. Earlier analysis suggests this enhance might be related to a rise in free vary poultry during the last 30 years.
A paper I coauthored in 2019 modelled how intervention methods might scale back threat, noting that: a shift of 25% of typical indoor farms to free-range farming practices would lead to a 6–7% enhance within the threat of a extremely pathogenic avian influenza outbreak. Present practices to deal with water are extremely efficient, lowering the chance of outbreaks by 25–28% in comparison with no water remedy.
Halving wild chook presence in feed storage areas might scale back threat by 16–19% whereas halving wild chook entry of potential bridge-species to sheds might scale back outbreak threat by 23–25%.
A big outbreak in Australia could be enormously expensive to business, trigger an enormous variety of birds to die and will doubtlessly pose a well being threat to people.
Though vaccines for avian influenza for poultry can be found, these would solely be thought of if an outbreak grew to become widespread.
Following acceptable biosecurity practices on poultry farms continues to be a very powerful prevention instrument we have now to keep away from outbreaks.
