Rising threat: Australia intensifies surveillance amid growing concerns over H5N1 bird flu strain
- Replies 180
As the world grapples with various health challenges, a new concern is on the horizon for Australians, particularly those who have seen many health scares in their lifetimes.
Australia's disease authorities are ramping up surveillance in response to a new strain of bird flu that has raised concerns among health officials.
This proactive approach aims to monitor potential risks to both wildlife and human health, highlighting the ongoing vigilance needed in managing infectious diseases.
The Australian Centre for Disease Preparedness (ACDP) has issued a warning about the potential arrival of the H5N1 bird flu strain, a virus that has already wreaked havoc in regions to Australia's north and south.
The H5N1 strain is not new to the global stage; it has been detected in farm workers in the United States and has crossed into a range of animal species, including dairy herds.
The Colorado Public Health Department has confirmed human cases of the strain in poultry workers, raising the alarm about the virus's ability to jump from animals to humans.
The ACDP is closely monitoring the situation, as the risk of the H5N1 bird flu appearing in Australia is increasing, particularly with the approach of spring.
Senior research scientist at the ACDP, Dr Frank Wong, highlighted the remoteness of Northern Australia as a potential hurdle for effective surveillance.
Australia was not along the migration routes of large water birds like ducks and geese that travel long distances and have contributed to the global spread of H5N1 bird flu.
However, authorities noted that birds from Asia that interact with infected migratory birds could potentially introduce the virus to Australia.
Moreover, they indicated there was also a risk from the south after an elephant seal was discovered dead in Antarctica with the H5N1 virus.
‘Where it has touched base in Antarctica is basically south of Chile and Argentina,’ Dr Wong said.
‘That part of the Antarctic continent is pretty much the opposite side of Antarctica closest to Australia.’
He stated that more information about the risk from Antarctica would be available after winter.
‘The impact to bird and animal species in Antarctica is still relatively unknown because the detection is quite recent, and it's now the Antarctic winter,’ Dr Wong continued.
‘As spring comes, we will know a little bit better how the virus may either have any continuing impact to birds in the Antarctic continent or whether we're no longer detecting the virus.’
The Centers for Disease Control and Prevention (CDC), the leading health authority in the United States, reported that the risk to humans remains low, even as more farm workers test positive for H5 bird flu.
The virus has been detected in over 100 dairy herds across at least 12 states. Farm workers involved in culling infected chickens and dairy workers milking affected herds have contracted the virus.
The centre described these cases as ‘concerning’ due to the potential for severe illness and broader outbreaks.
‘If these viruses were to change to spread easily from person-to-person, it could trigger a pandemic, though, to date, we have not seen genetic changes in the virus that would make it more likely to transmit between humans,’ the CDC explained in a statement.
Back home, Australia is not immune to avian influenza threats. Outbreaks of H7 strains of avian influenza at poultry farms have been reported in three states and territories.
According to ACDP Director Debbie Eagles, the extent to which these outbreaks will last is still uncertain.
‘It is the most number of highly pathogenic avian influenza strains that have been detected at the same time in Australia,’ Dr Eagles stated.
‘It's difficult to say how long they will take to control.’
While the H5 and H7 strains have been known to infect humans, health authorities maintain that the risk from H7 remains low.
They assure the public that eggs and poultry meat are safe to consume when handled and cooked according to standard food handling practices.
As Australia intensifies its surveillance efforts in response to the rising concerns surrounding bird flu, the situation has taken a more serious turn with the recent declaration of the country's first human case.
This development underscores the importance of remaining vigilant and informed about the ongoing risks associated with avian influenza, highlighting the need for continued awareness and precautionary measures among the community.
