health of people is connected to the health of animals and the environment
what percent of human pathogens are zoonotic
61

measles
herpes
smallpox
general categories of interactions between host and virus (4)
stable
evolving
dead end
resistent
stable interaction
maintains the virus in a species
evolving interaction
passage of virus from experienced to native populations of the same or other host species
dead end
one way passage from one host species to another
resistant
host blocks infection completely
emerging viral infections
NEW human infections that are derived from stable pre existing host-virus relationships that serve as reservoirs for particular viruses
out of emerging pathogens ____% are zoonotic
75
zoonotic pathogens are basically what
emerging viral infections
reservoir
an animal or innate object where an infectious agent lives
source of infection
animal or object that is the origin of transmission of a disease
vector
a living organisms that communicates an infectious agent from an infected to a susceptible animal (mosquito)
vehicle
object acting as an intermediate between an infected hist and a receptive host (food)
hotspot
place in the world that has a high rick of emerging infectious disease events
genetic drift
mutations and repeated infections in human host
genetic shift
re-assortment and emergence of new virus and global spread
emerging virus
the causative agent of a new of previously unrecognized virus infection in a population
