Viral diseases have an important impact on public health world-wide. New genomic technologies are providing infectious disease scientists with a unique ability to study at the genetic level those viruses that cause disease and the interactions they have with infected hosts. In this book, the authors present new research in viral genomes. Topics include improvements in HSV-1 derived amplicon vectors for gene transfer; viral genome research in papillomavirus; the synthetic synthesis of viral genomes; and a novel bioinformatic method to analyse over 10,000 influenza virus strains simultaneously.
