Scientific Reports - Superior replication, pathogenicity, and immune evasion of a Texas dairy cattle H5N1 virus compared to a historical avian isolate

We measured stability of infectious influenza A(H5N1) virus in irradiated raw milk and wastewater and on surfaces. We found a relatively slow decay in milk, indicating that contaminated milk and fomites pose transmission risks. Although the risk is low, our results call for caution in milk handling …

The longer we allow the virus to run rampant through animal populations, the greater our chances of disaster.

The spread of H5N1, the bird flu, since 2021 is unprecedented and unlike anything we have witnessed in the last century.

No evidence of human-to-human transmission was identified. Evidence Rating Level: 4 (Below Average) Study Rundown: Avian influenza A(H5N1) viruses are known for causing disease in poultry and dairy cows in the United States. Since their

The Food and Veterinary Agency has announced that it has increased control measures for shipments of products of animal origin, live animals and poultry from the Durrës area, Albania

The USDA’s Animal and Plant Health Inspection Service (APHIS) has reported 110 new cases of Highly Pathological Avian Influenza (HPAI) over 27 different states in the past 30 days.

The global outbreak of clade 2.3.4.4b H5N1 highly pathogenic influenza A virus (HP H5N1) has had an unprecedented impact on wild birds including raptors, but long-term population impacts have not been addressed. To determine if raptors survive infections with HP H5N1, raptors from the upper Midwest …

In this article, we present an assessment of the risk of the potential introduction and spread of highly pathogenic avian influenza (HPAI) in cows in Bulgaria. In the spring of 2024, we witnessed an unprecedented spread of the virus in dairy herds in the USA. This crossing of interspecies barriers b …
