disease definitions Flashcards
(intervention?) prior to exposure to agent, vaccine, sanitation
primary intervention
(intervention?) early detection through screening tests, before clinical signs, may or may not affect disease outcome
secondary intervention
(intervention?) after clinical signs of disease are apparent, intervention ( surgery, treatment, medical), intended to improve productivity and quality of life and/or surviorship
tertiary intervention
definition of host
animal that supports the replication or development of an agent
definition of agent
factor whose presence is required (bacteria, viruses, parasites, toxins, etc.)
definition of environment
macro climate, micro climate, presence of fomites or vectors, contact with soil
what is preventative medicine?
determining the most cost-effective intervention points
increase immunity, increase innate resistance,
decrease transmission, decrease reservoir,
remove nutritional constraints
what are the 5 biosecurity tools in disease-control?
quarantine testing imports vaccinations sanitation prophylactically treat all
3 factors of quarantine
separation in space
age-segregation
risk-segregation
disease is a result of what 3 multi-factor causes
host
environment
agent
how sick is an animal when you put it on primary prevention?
not sick at all
is testing for a disease primary or secondary intervention?
primary
what is the least efficient form of intervention?
tertiary
does disease occur randomly in a population?
NO
biosecurity
management to PREVENT THE SPREAD of pathogens or toxins that may damage the health of the population
biocontainment
management to CONTROL THE SPREAD of disease or intoxication within the population
endemic =
balanced
epidemic =
more disease than expected
what is quarantine?
separation of incoming animals/people from the resident population
what is testing imports?
identify particular pathogens you want to exclude and don’t import positive individuals
what is the purpose of vaccinating?
an attempt to improve immunity
what is sanitation?
keeping things clean and well-managed
how can you prophylacticaly treat all?
internal parasite control
external parasite control
