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

By Texas Biomedical Research Institute

“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’s rapid mutation when it infects a new host species.”
