Glasgow University scientists have made an important discovery about bird flu and its impact on humans. They found that bird flu strains can bypass our body’s defenses, but they are getting closer to identifying the most dangerous ones. By studying a part of our DNA called BTN3A3, which becomes active during infection, they found that it can stop bird flu viruses from spreading in our nose, throat, and lungs. This breakthrough allows us to better monitor and control potential pandemics by examining the genetic makeup of bird flu strains.

Scientists want to study the genetic code of bird flu strains in birds to identify the ones that can harm us. They will take targeted actions to control their spread. The recent avian flu outbreak has shown how important it is to take such actions, as it has affected many birds. While some bird flu samples have resisted our body’s defense mechanisms, there are other ways the virus can threaten human health. However, this discovery, along with genetic monitoring, gives us useful information to assess future disease risks and protect public health.
