Editorial: Bird flu death highlights head-scratching vaccine policy from Louisiana officials
Editorial: "We don't expect our public health officials to have all the answers. But when they do have information that can save lives, it's sheer dereliction of duty to hide it. Vaccines work, and Louisiana officials need to stop the pandering and say so."

First US human death from bird flu is more serious than you may think
Two months shy of the fifth anniversary of COVID-19 being declared a global pandemic, the US has recorded its first human death as a result of avian influenza H5N1 infection. The unidentified Louisiana man contracted the virus through contact with infected wild and domestic birds on his property in…

A child in California is presumed to have H5N1 bird flu, according to the San Francisco Department of Public Health (SFDPH). As of Dec. 23, there had been 36 confirmed human cases of bird flu in the state, according to the California Department of Public Health (CDPH). This represents more than half of the human

A human isolate of bovine H5N1 is transmissible and lethal in animal models
A human isolate of bovine H5N1 is transmissible and lethal in animal models
The outbreak of clade 2.3.4.4b highly pathogenic avian influenza viruses of the H5N1 subtype (HPAI H5N1) in dairy cattle in the USA has so far resulted in spillover infections of at least 14 farm workersSUP1, 2–3/SUP, who presented with mild respiratory symptoms or conjunctivitis, and one individual with no known animal exposure who was hospitalized but recoveredSUP3,4/SUP. Here we characterized A/Texas/37/2024 (huTX37-H5N1), a virus isolated from the eyes of an infected farm worker who developed conjunctivitisSUP5/SUP. huTX37-H5N1 replicated efficiently in primary human alveolar epithelial cells, but less efficiently in corneal epithelial cells. Despite causing mild disease in the infected worker, huTX37-H5N1 proved lethal in mice and ferrets and spread systemically, with high titres in both respiratory and non-respiratory organs. Importantly, in four independent experiments in ferrets, huTX37-H5N1 transmitted by respiratory droplets in 17–33% of transmission pairs, and five of six exposed ferrets that became infected died. PB2-631L (encoded by bovine isolates) promoted influenza polymerase activity in human cells, suggesting a role in mammalian adaptation similar to that of PB2-627K (encoded by huTX37-H5N1). In addition, bovine HPAI H5N1 virus was found to be susceptible to polymerase inhibitors both in vitro and in mice. Thus, HPAI H5N1 virus derived from dairy cattle transmits by respiratory droplets in mammals without previous adaptation and causes lethal disease in animal models.

Weather, migratory activity affecting H5N1 spread - Brownfield Ag News
An animal disease specialist says the recent uptick in avian influenza outbreaks is in part due to the milder winter weather. Dr. Keith Poulsen with the Wisconsin Veterinary Diagnostic Center tells Brownfield many lakes and ponds have not frozen, so some wild birds are not migrating south as early as they normally would, putting more […]

Predicting H5N1 disease severity based on T cell responses
New research led by scientists at La Jolla Institute for Immunology (LJI) suggests that many people already have immune cells on "stand by" to fight the H5N1 virus, also known as highly pathogenic avian influenza.
