{Abstract} Introduction :  The late autumn epizootic of the highly pathogenic avian influenza virus (HPAIV) subtype H5N1 in Serbia in 2023 caused massive mortality in the migratory population of common cranes (Grus Grus). This is the first time HPAIV has been identified in the common crane in Serbia, leading to mass mortality of this bird species. Methods :  To understand the pathological impact of HPAIV in cranes, we evaluated the pathological changes in the tissues of common cranes. Additionally, we report genomic characterization of HPAI/H5N1. In total, 14 juvenile common crane carcasses were examined. Results :  Infected birds primarily exhibited neurologic signs , including ataxia and incoordination. Grossly, necrotizing pancreatitis was the most common finding, while microscopic lesions included necrosis, inflammation and hemorrhages in the lungs, spleen, brain, liver and kidneys . Based on RT-PCR, all birds were infected with the HPAI H5N1 virus, as viral RNA was d...

 {Excerpt, edited} Updated December 23, 2024​ --  ​​​The current risk to the public remains low.  ​​ -- No person-to-person spread of bird flu has been detected in California.  -- People rarely get bird flu , but those who interact​ with infected dairy cows, poultry, or wildlife ​have a greater risk of infection.​​ -- Pasteurized milk and dairy products are safe to consume. Pasteurization inactivates the bird flu virus.​​ -- CDPH is working to protect public health related to bird flu. We monitor infection data, evolving science, and the people affected. Our knowledge will change as we learn more. We are committed to reducing the impact to those at highest risk.
