High number of HPAI H5 virus infections and antibodies in wild carnivores in the Netherlands, 2020–2022
Wild birds, particularly those belonging to the orders Anseriformes and Charadriiformes, are the natural host of a wide range of low pathogenicity avian influenza (LPAI) viruses.
How the current bird flu strain evolved to be so deadly
Genetic changes to avian influenza viruses have led to spread among many wild species, creating an uncontrollable global outbreak.
The episodic resurgence of highly pathogenic avian influenza H5 virus
Highly pathogenic avian influenza (HPAI) H5N1 activity has intensified globally since 2021, increasingly causing mass mortality in wild birds and poultry and incidental infections in mammals.

BTN3A3 evasion promotes the zoonotic potential of influenza A viruses
Spillover events of avian influenza A viruses (IAVs) to humans could represent the first step in a future pandemic. Several factors that limit the transmission and replication of avian IAVs in mammals have been identified.
We need to keep an eye on avian influenza
H5N1 avian influenza viruses of the A/goose/Guangdong/1/96 lineage have been circulating in wild birds for many years, have inflicted significant economic losses on the poultry industry and have caused zoonotic infections since 1997.
Influenza A(H5N1) detection in two asymptomatic poultry farm workers in Spain, September to October 2022: suspected environmental contamination
In autumn 2022, the Spanish Influenza National Reference Laboratory (NRL) confirmed the detection of influenza A(H5N1) in samples from two asymptomatic workers linked to an outbreak in a poultry farm in Spain.
Highly pathogenic avian influenza A(H5N1) virus infection in farmed minks, Spain, October 2022
In October 2022, an outbreak in Europe of highly pathogenic avian influenza (HPAI) A(H5N1) in intensively farmed minks occurred in northwest Spain. A single mink farm hosting more than 50,000 minks was involved.
H7N9 avian influenza virus infection in men is associated with testosterone depletion
Human infections with H7N9 avian influenza A virus that emerged in East China in 2013 and caused high morbidity rates were more frequently detected in men than in women over the last five epidemic waves.
