Final Exam Cumulative Portion Flashcards
The constant /expected occurrence of a disease w/in a given geographic area / population
Endemic
a major increase in disease incidence affecting a large number of animals / spreading over a large area
Epidemic
a disease that occurs irregularly and haphazardly
Sporadic
a geographically widespread (sometimes global) epidemic
Pandemic
the % of deaths among the clinically ill animals
Case-Fatality Rate
% of animals in a population that die from a particular disease over a specified period of time
Mortality Rate
virus cycles between humans and insect vectors
Urban cycle
(epizootic cycle): the virus is transmitted between domestic animals and the primary / accessory insect vector
Rural cycle
(Enzootic cycle) natural transmission of virus between wild animals/birds (vertebrate hosts) and primary insect vectors.
Sylvatic cycle
a host from which infectious agents are not transmitted to other susceptible hosts.
Dead-end host
a host within which the level of virus becomes high enough that an insect vector becomes infectious when it feeds on it
Amplifying host
an arthropod that acquires the virus from an infected wild animal and subsequently transmits it to a human/ secondary host.
