Analysis of the Monophyletic Lineage of Avian Influenza H5N1 Which Circulated in Venezuelan Birds During the 2022-2023 Outbreak - PubMed
Avian influenza subtype H5N1 has caused outbreaks worldwide since 1996, with the emergence of the Guandong lineage in China. The current clade 2.3.4.4b has evolved from this lineage, with increased virulence and mass mortality events in birds and mammals. The objective of this study was the analysis …
Highly pathogenic avian H5N1 influenza A virus replication in ex vivo cultures of bovine mammary gland and teat tissues - PubMed
Since early 2024, highly pathogenic avian influenza H5N1 viruses have been causing outbreaks in dairy cattle in the United States. Here, we compared the replicative capacity of A/dairy cattle/Texas/24-008749-001/2024 (H5N1; Cow-H5N1) isolated from a dairy cow, A/chicken/Ghana/AVL-76321VIR7050-39/202 …
Chicken C4BPM facilitates replication of H5N1 and H9N2 Avian Influenza Viruses by inhibiting the production of type I interferons - PubMed
Avian influenza viruses (AIVs) are potential pandemic of global concern, posing a major threat to both the poultry industry and human health. Host factors play a key role in the replication of AIVs, while the function of complement component 4 binding protein, membrane (C4BPM) in this process is sti …
Why the incidence of bird flu is spiking is not clear, Vitz said it could be tied to this year’s cold weather. With ponds frozen, our region’s waterfowl are congregating in fewer patches of open water, he said, making the spread of disease easier.
WELLFLEET — If you feel like you’ve been noticing a lot of dead birds lately, you’re not alone. According to State Ornithologist Andrew Vitz, we are in the midst of […]
The decision to go ahead and look for H5N1 is based on whether or not that patient has close proximity to animals, a lab exposure, or close exposure to someone with known avian flu
The threat has gotten serious enough that hospitals are now looking for the disease (When it makes sense clinically)
Veterinarian warns cat owners about H5N1 risks amid rising cases
Veterinary and public health officials are urging cat owners to remain vigilant as cases of Highly Pathogenic Avian Influenza, or H5N1, commonly known as bird flu, have been detected in domestic cats.
The Centers for Disease Control and Prevention says that 40 out of the 67 confirmed human bird flu cases since 2024 have been linked to exposure to dairy cows sick with the virus
The strain, called D1.1, was behind a human death from bird flu last year.
Now it looks like we have new strains of virus that may escape some of the immunity associated with the other strains of viruses that could exacerbate the epidemics among animals and wildlife
Genome sequencing of milk from Nevada has identified a different strain of bird flu in dairy cows for the first time, the USDA says
No human bird flu cases have been linked to the consumption of raw milk. However, health officials still remain wary of raw milk consumption, citing a lack of data around whether humans can contract the bird flu from drinking it
H5N1 bird flu spills over again; Nevada cows hit with different, deadly strain
So far, the US has tallied 67 human cases of H5N1 since the start of 2024. Of those, 40 have been in dairy workers, while 23 were in poultry workers, one was the Louisiana case who had contact with wild and backyard birds, and three were cases that had no clear exposure.
Should we be worried about bird flu, the 'unpredictable shape-shifter'?
Bird flu has decimated poultry flocks and infected cattle herds. The risk to humans is currently low, but that could easily change as influenza can rapidly change.
Bird flu is taking a massive toll on wild animals, researchers find
Researchers are reporting mass die offs of wild birds and sea mammals due to bird flu. They're tracking the deaths to better understand the virus and how it might create a greater threat to humans.
USDA milk testing shows different strain of H5N1 bird flu in Nevada dairy herds
The U.S. Department of Agriculture announced Wednesday that four dairy herds in Nevada recently found to be infected with H5N1 bird flu were in fact infected with a different strain of the virus than has been circulating in cows for the past year.
US Department of Agriculture detects second bird flu strain in dairy cattle

DEC launches link to report suspected bird flu in wild birds
ALBANY — If people suspect a wild bird may be exhibiting avian flu symptoms, they now have a way to report it. On Thursday, the state Department of Environmental Conservation announced an online platform for people to report suspected Highly Pathogenic Avian Influenza (HPAI) outbreaks in wild birds.
