If this route proves to be common to many animal viruses it might point to new ways in which viral infections could be attacked with drugs.

Papers are accepted on all viruses, irrespective of host species, but the modern journal's primary focus is on animal viruses.

The vast majority of human and animal viruses do not cause cancer, probably because of long-standing coevolution between the virus and its host.

The core particles in the case of the animal viruses and the structures of these inner nucleoprotein particles are similar.
