infectious disease surveillance Flashcards
object of surveillance
early detection of disease
what is surveillance
continuous investigation of a given population to detect occurrence of disease for control purposes, which may involve testing of a part of the population
all regular activities aimed at ascertaining the health status of a given population with the aim of early detection and control of animal diseases of importance to national economies, food security and trade
what do we want to know with surveillance
how fast a disease is spreading
in which direction is it going
the size of the populations threatened
to know how many vaccines to purchase, number of staff to deploy etc
what is monitoring
on-going programmes directed at detection of changes in the prevalence of disease in a given population and its environment
more specific activities that will follow as part of an early reaction should surveillance activities indicate introduction of disease
focuses more on identified disease in order to know changes in prevalence, rate and direction of spread
passive surveillance
routine programmes that run usually partly direct visual or indirect, relying on farmer interviews and notifications
to survey the landscape for livestock diseases and detect changes in status
active surveillance
any activity which is frequent, intensive and aims at establishing the presence or absence of a specific disease
4 levels of disease control activities
individual
institutional
community
global
suspected diseases
2 or more sick or dead animals with the same or similar signs
sudden death of animals without visible cause
the results of lab tests, clinical sign to disease or epidemiological circumstances that justify suspicion of disease
confirmed case of disease
case officially confirmed in living or deas
location of outbreak is place where animals are held where case of disease has been officially confirmed
primary location of outbreak is place where a disease breaks out which is not epizootiologically linked with a previous outbreak
what is secondary location of outbreak
location which is epizootiologically linked with a previous outbreak location within the same region
duties and obligations of the vet
mandatory reporting of a suspected disease within 24h
notification of every confirmed case of disease
weekly reports about location of outbreak until registration of end of the outbreak
what info must vet send
exact number of animals on farm
results of preliminary epizootiological/epidemiological research
