| infectious disease | negative effects on a host organism cause by a parasite / pathogen |
| parasite / pathogen | an organism that exploits a single host individual per life-story stage, causing disease |
| infection | the process by which a parasite exploits its host, signified by its presence in the host but may or may not cause disease |
| transmission | the process by which a pathogen passes from a source of infection to a new host individual and infects that host |
| VerVecTIDES | modes of transmission |
| Density-dependent transmission | via direct, indirect contact, creates linkages to other variables (climate, competition, predation), regulate host populations |
| Frequency-dependent transmission | via STIs, vectored diseases, with greater proportions of infected, pathogen can invade and persist at low host population densities |
| Pop, Ext, Colon, In, Sp | biogeography assumptions |
