The recent acceleration in human virus discovery by metagenomics indicates that many viruses escaped prior detection due to limitations of preexisting technologies. It is now conceivable that all viral species commonly infecting human (i.e., the human virome) will soon be determined. As the value of the human genome and microbiome has become widely recognized, providing crucial reference genomes and opening unanticipated avenues of research, the genetic characterization of the human virome also holds great promises ." (Etc) We hear a lot about genome, virome, microbiome as of late. I think it has the possibility to help us, at long last.
