Research aims to strengthen NZ's defenses against bird flu

Research aims to strengthen NZ's defenses against bird flu

 


Scientists are collecting environmental samples such as bird faeces in a research project aimed at understanding how and where bird flu and other viruses may affect New Zealand. There is.

This comes after the highly contagious H5N1 avian influenza was recently discovered in Antarctica, making Oceania the only continent yet to be reached by the highly pathogenic virus.

The Te Niwha research project is led by Professor Gemma Geoghegan from the University of Otago and Dr David Winter from the Environmental Science Research Institute (ESR), working with local communities and iwi.

The team will work on developing portable field environmental DNA detection tools for avian influenza and other viruses as part of an enhanced national surveillance system.

Geoghegan said bird flu had killed millions of birds, spread to mammals such as seals and polar bears, and even infected humans.

Waterfowl carry a variety of viruses and typically spread them to new species and environments.

“It is unclear what role wild waterfowl play in virus transmission in Aotearoa New Zealand and what impact this will have on human and animal health in the near future.

“This knowledge gap leaves Aotearoa New Zealand vulnerable to the introduction of highly pathogenic avian influenza viruses, with unavoidable impacts on wildlife, agriculture and potentially human health.”

Samples are being collected from areas where seabirds, shorebirds and waterfowl live.

It has also been collected from urban parks where humans come into contact with birds and from birds in the subantarctic and Chatham Island regions.

Taonga species such as hoiho/yellow-eyed penguins are sampled in collaboration with iwi and the Department of Conservation.

Winter said much has been learned about using genomics and wastewater to monitor viruses during the COVID-19 pandemic.

“Just as we did with COVID-19, we want to ensure we have the knowledge and technology needed to respond to the next threat.

“Using an innovative combination of genomic technologies, we unraveled the transmission networks and evolution of avian viruses already present in Aotearoa, demonstrated the use of large-scale environmental sampling for disease surveillance, and demonstrated the relevance of Quantify the disease risk of such viruses, including any virus that has a negative impact on public health.”
