Table 1

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
