H5N1 genetic structure

H5N1's genetic structure is defined by its segmented RNA genome composed of eight gene segments. These segments encode crucial viral proteins responsible for replication, host adaptation, and evading the host's immune response. This segmented nature allows for reassortment with other influenza viruses, leading to the emergence of novel strains with potentially altered virulence and transmissibility, representing a significant concern for public health. Genetic analysis focuses on tracking mutations and reassortment events to understand the virus's evolution and predict its pandemic potential.
