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
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
