Retrovirus that comes from chimps develops into human pathogen: kills t-cells. Victims die of multiple infections: ~(cid:1004). (cid:1009)% of the (cid:449)o(cid:396)ld(cid:859)s population infected. Obligate parasites need a host to complete their life cycle. Network of host interactions: local vs. distant. Presence of a vector: pathogens transmitted by respiratory droplets require host mobility. Rhinovirus: parasites that use an intermediate vector for transmission can immobilize a host and be much more virulent. Malaria, yellow fever, dengue: parasites that are enduring and depend on the mobility of a healthy host can be much more virulent. Pathogens in diffuse population = herpes viruses in all populations: always chronic, never cleared. Venereal transmission: always chronic diseases caused by persistent infectious agents. Virulent: how bad of a disease it causes. Latent: present, but not replicating: can be reactivated.
