Final Flashcards
The study of incidence and control of disease and epidemics
Epidemiology
Pattern of disease in time and space
Occurrence
Proportion or percent infected at a given time
Prevalence
Number of new cases per unit time at a place
Incidence
Extent of resistance, immunity, or lack thereof
Susceptibility
Speed and severity of symptoms
Virulence
Persistent, moderate, steady disease occurrance
Enzootic
Outbreaks, pulses in disease occurrence
Epizootic
An animal that physically carries a disease agent from host to host
Vector
The spread of disease from infectious to susceptible hosts
Transmission
Parent to offspring disease transmission
Vertical transmission
Disease transmission between individuals of the same cohort
Horizontal transmission
A host that sustains a disease agent
