New Zealand confirms first H5N1 bird flu case

New Zealand has confirmed its first case of the highly pathogenic H5N1 avian influenza after a migratory brown skua seabird found on a beach near Wellington tested positive, prompting authorities to intensify surveillance and begin vaccinating some of the country's most endangered bird species,according to agency reports.
Announcing the development on Wednesday, Biosecurity Minister Andrew Hoggard said there was no evidence so far of widespread transmission among wild birds or any infections in poultry."There is no evidence of any mass mortality in wildlife or transmission between wild birds in New Zealand. There has been no detection in poultry," Hoggard said in a statement.

The detection comes weeks after H5N1 was reported in Australia, making New Zealand the latest country to record the virus, which has spread across wild bird and mammal populations worldwide since 2021, causing millions of bird deaths and outbreaks in poultry and dairy farms.Hoggard said New Zealand could experience a pattern similar to neighbouring Australia, where 14 confirmed or presumed positive H5 bird flu cases had been recorded as of Wednesday. He added that authorities had been preparing for the virus by working closely with the poultry industry to strengthen biosecurity measures and improve outbreak preparedness.
In response to the detection, health officials have launched a vaccination programme targeting around 300 core breeding birds from five of New Zealand's most endangered species, including the flightless takahē and kākāpō, in an effort to protect vulnerable populations from the virus.New Zealand's unique birdlife is considered particularly susceptible to avian influenza because many native species evolved in isolation for millions of years without land mammals. As a result, several species are flightless, nest on the ground and have limited natural defences against predators or emerging diseases.
Conservationists fear an uncontrolled outbreak could further threaten species already facing pressure from habitat loss and introduced predators such as stoats, rats and feral cats.Brett Gartrell, professor of wildlife health at Massey University, warned that the virus could have devastating consequences for the country's biodiversity."We are incredibly worried about New Zealand’s biodiversity because our birds have never had to deal with anything like this before," Gartrell told Reuters."If it spreads quickly in New Zealand, we could be in trouble … those core group of birds that (officials) want to protect with the vaccination won’t be fully immune if it spreads too quickly," he added.
