Vertebrate virus families - Diagram of the families of viruses that include human, animal and zoonotic pathogens.
Diagram illustrating the shapes and sizes of viruses of families that include animal, zoonotic and human pathogens. The virions are drawn to scale, but artistic license has been used in representing their structure. In some, the cross-sectional structure of capsid and envelope are shown, with a representation of the genome; with the very small virions, only their size and symmetry are depicted.
