Some animal viruses have
a membrane outside
nucleocapsid:
Latent vs. persistent Persistent slow release of the virus without cell death
infection latent virus lays dormant until activated by a stimulus
Viroids= short pieces of naked RNA, replicated
"naked" RNA; common in

can cause disease:
When a genetic change Antigenic shift
occurs to allow an animal
pathogen to infect
humans:
