Categories of pathogens that pose threats of being stably harmful in human populations because of reduced dependence on host mobility
| Characteristics allowing transmission from immobile hosts |
Association with lethality |
Reference |
| arthropod-borne transmission | lethality higher among arthopod-borne pathogens than among directly transmitted pathogens | (16) |
| water-borne transmission | lethality of diarrheal bacteria correlated with tendencies for waterborne transmission | (42) |
| attendant-borne transmission | lethality of E. coli correlated with duration of attendant-borne cycling | (20, 41) |
| durability in the external environment |
lethality of respiratory-tract pathogens correlated with durability |
