New Zealand confirms first avian flu case in migratory bird

New Zealand has confirmed its first detection of the H5N1 avian influenza strain, identified in a migratory seabird found dead on a Wellington beach. This marks the final continent, Oceania, to report the presence of the virus, following its detection in Australia just a month prior.

There is no evidence of mass mortality in wildlife nor of transmission between wild birds in New Zealand. No case has been detected in poultry.

Biosecurity Minister Andrew Hoggard assured the public that there is no evidence of widespread mortality among wildlife or transmission between wild birds within New Zealand. Crucially, no cases have been found in poultry. Hoggard emphasized that the virus poses "a low risk to public health" and urged citizens to report any findings of sick or dead birds to the authorities.

The country is reportedly "well prepared" to respond to any potential outbreak. In anticipation of the virus's impact, authorities have initiated a vaccination program for some of New Zealand's most threatened endemic bird species, including the takahe and kakapo, which are particularly vulnerable due to their isolated habitats.

The virus represents 'a low risk to public health'.

The confirmation in New Zealand follows Australia's report on June 20 of the H5N1 strain in a brown skua found near death on a remote beach. Since then, Australia has documented further avian flu cases in various jurisdictions, including infections in native bird populations. The H5N1 strain, known for its rapid contagion, severe symptoms, and high mortality rates in birds, has caused significant global outbreaks since its first detection in 1996.

Oceania was the only continent where the H5N1 strain had not been detected.
