H5N1 Transmission

Bird flu is infecting more people than we think. We need to stop it now before a new pandemic begins

Authorities in New York state have temporarily closed all live poultry markets in New York City and three suburban counties after detecting bird flu at seven markets within the past week, according to a notice on Friday.

The order affects roughly 80 markets in New York City and in several nearby counties. Gov. Kathy Hochul described it as a “proactive” step to help curb the spread of bird flu.

Globally, human cases of the highly pathogenic avian influenza A(H5N1) have shown a wide spectrum of disease severity while recent US cases have generally been clinically mild, prompting experts to call for a balanced approach to this “formidable challenge.”

A bird flu variant linked to the death of a Louisiana resident has now been found in cattle in Nevada.

The data, which appeared fleetingly online on Wednesday, confirmed transmission in two households. Scientists called on the agency to release the full report.

It’s probably not good that one former USDA scientist called the outbreak a 's— show.'

When it comes to the potential of H5N1 avian flu, otherwise known as bird flu, picking up mutations that may lead to human-to-human spread, that "train has already left the station," warns one infectious disease expert.

Leading virologist Angela Rasmussen breaks down everything you should know about the latest bird flu outbreak, including how worried Americans should be.

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 …

The threat has gotten serious enough that hospitals are now looking for the disease (When it makes sense clinically)

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. The platform was designed as part of […]

The USDA’s Animal and Plant Health Inspection Service (APHIS) has reported 124 new cases of Highly Pathological Avian Influenza (HPAI) over 32 different states in the past 30 days, with egg availability in some grocery stores across the country impacted.

With human infections of avian flu present in the U.S., workers remain most vulnerable to the virus.

Reintroduced to U.S. Congress on February 3, 2025, the Expanded Food Safety Investigation Act (EFSIA) seeks to grant the U.S. Food and Drug Administration (FDA) the authority to collect microbial samples from concentrated animal feeding operations (CAFOs). The bill is sponsored by Representative Rosa DeLauro (D-CT) and Senator Cory Booker (D-NJ). Concentrated animal feeding operations (CAFOs), also referred to as “factory farms,” are large-scale facilities that raise food-producing animals in confinement. At present, FDA lacks the authority to conduct microbial sampling on factory farms during foodborne illness outbreak investigations, and therefore, public health investigators are frequently denied access to CAFOs.

Avian influenza has continued to challenge the agricultural sector, impacting nearly every state over the past two years. Minnesota, a state where turkey production is a cornerstone of the economy, is no exception. For local...

The ongoing outbreak of “bird flu” has spread widely across both wild bird populations and commercial poultry operations …

Scientists say the world needs to learn more about H5N1 bird flu and how it spreads

While the developments may not raise the risk of a pandemic, they could create more havoc for farmers, worsen egg shortages and expose surveillance gaps.

HAGERSTOWN- The Maryland Department of Agriculture has announced the first presumptive positive case of H5 avian influenza in a commercial broiler farm in Worcester County. This is the fifth case of highly pathogenic […]

The recent outbreak of the H5N1 avian influenza virus in the U.S. and the potential for it to mutate has raised concerns among the scientific community that it could result in human-to-human transmission and a new pandemic. Farmers are also concerned. VOA’s Veronica Balderas Iglesias reports.

Scientists were slow to recognize that Covid spreads through the air. Some are now trying to get ahead of the bird flu.
