  1. From poultry flu to wild bird flu - H5N1

    * "Every outbreak of bird flu in Australian from 1976 to 2024 has arisen on a large, commercial poultry farm."

    * A suspected bird flu case was detected on mainland Australia

    "Australia had been the last continent free of this deadly strain of bird flu."

    "Infection usually happens after close contact with infected poultry — for example, chickens, ducks, turkeys, geese – or contaminated environments."

    "In the US, for example, since the arrival of this virus they've had to cull and destroy over 200 million chickens."

    "In February 2025 the H7N8 strain was detected at multiple poultry farms in Victoria's north-east." >>

  2. As I was looking out of the window yesterday - a surprise visit by a small flock of King Parrots! Didn’t manage to get a photo - so found this glorious male in my archives. They were a bit quick, but I think there were a couple of males, plus a few females and juveniles.

    Abstract

    Background: Usutu virus (Orthoflavivirus usutuense, USUV), a neurotropic arthropod-borne RNA virus of the family Flaviviridae, is a zoonotic virus that has spread throughout the European continent over the last three decades, since its emergence in Italy in 1996. However, no cases of USUV have been reported in Portugal so far.

    Material and methods: In the scope of an active surveillance program for Orthoflavivirus, we collected growing feather samples from 249 red-legged partridges (Alectoris rufa) hunted in southern Portugal during the 2021-2023 hunting seasons. Samples positive for USUV were subjected to whole genome sequencing and strain characterization.

    Results: Two partridges tested positive for USUV. Phylogenetic analyses of whole and partial genomes assigned the USUV strains to the African 3 lineage, specifically the African 3.1 sub-lineage.

    Conclusions: Our study confirms, for the first time, the circulation of USUV in wild birds in Portugal. Active surveillance of hunted partridges proved to be a useful, accessible, and cost-effective method for USUV monitoring, further supporting their value as effective sentinels for Orthoflavivirus surveillance. Given the ongoing circulation of USUV and the increasing risk of its spillover to other domestic and wild animals, and humans, additional efforts are needed to improve virus surveillance in Portugal from a One Health perspective.
