Due to ongoing sporadic H5N1 avian flu infections and brisk levels of seasonal flu activity, the US Centers for Disease Control and Prevention (CDC) today urged healthcare providers to subtype all influenza A specimens in hospitalized patients, especially those in the intensive care unit (ICU), as soon as possible.

However, none of this means we are "one mutation away" from a pandemic. The first highly pathogenic avian influenza virus of subtype H5N1 emerged in China in 1996. Since then, H5 viruses have spread widely in Europe, Africa, North America and Asia via ...

Mutations in one of the first human-isolated strains of H5N1 bird flu in the US were identified by the Texas Biomedical Research Institute.

Since early 2024, the U.S. has logged 66 human cases of H5N1. Scientists are keeping a watchful eye on the virus’s spread as we enter a new year.

As the Centers for Disease Control and Prevention (CDC) explains, bird flu is a disease caused by the influenza A virus. At the same time, recent CDC data shows that seasonal influenza A is rising across the U.

Seasonal influenza vaccines triggered protective immune responses against the H5N1 avian influenza virus primarily in younger people, indicating its potential use as a first line of defense during an eventful pandemic.

Human MxA protein suppresses mammalian H5N1 virus replication, but emerging mutations may enable partial evasion, raising concerns for human transmission.

With cases of avian influenza A(H5N1) continuing to rise among cattle and humans in the US, scientists and government health officials are preparing for the potential of the virus adapting to ...

The findings come at a time when outbreaks of bird flu -- a different subtype of the same ... of the highly pathogenic avian influenza (HPAI) H5N1 influenza virus currently circulating

The Lincoln-Lancaster County Health Department (LLCHD) today reported that H5 avian influenza has been detected in a local wastewater sample collected from the

CDC officials say they extended the guidance now because they are seeing more H5N1 patients whose illness they cannot track back to an infected bird or cow.
