First U.S. H5N1 Death Sparks Urgency: Scientists Warn That Bird Flu Is Mutating Faster Than Expected

Posted by in categories: biotech/medical, neuroscience

Researchers at Texas Biomed have identified nine mutations in a strain of bird flu found in a person in Texas. Bad news: This strain shows an increased ability to cause disease and is more effective at replicating in the brain. Good news: Current approved antiviral treatments remain effective against this strain.

Researchers at the Texas Biomedical Research Institute (Texas Biomed) have identified a strain of bird flu isolated from a human in Texas that carries a distinctive set of mutations, making it more adept at replicating in human cells and causing severe disease in mice. This strain was compared to one found in dairy cattle, and the findings are detailed in Emerging Microbes & Infections.

The discovery underscores a significant concern about the H5N1 strains of bird flu currently circulating in the U.S.: the virus.
