Flashcards in Preventative Care Strategies 2 Deck (41):
1

reservoir

the reservoir of an infectious agent is the habitat in which the agent normally lives, grows and multiples

2

removing infected individuals

infection may be removed from a herd by testing and slaughtering those found to be infected

3

mass therapy

usually restricted to a local situation in which all potentially infected animals or people are treated without first testing them to identify infected individuals

4

what is the risk of mass therapy?

development of resistant strains and adverse side effects of therapy

5

environmental manipulation

a method of reservoir neutralization designed to break the chain of transmission between the portal of exit of the infected (shedder) host and the susceptible host by reducing survival of the agent in vector or vehicles (food, water, soil, vegetation)

6

biological control

use of natural enemies to manage mosquito populations, such as predatory fish that feed on mosquito larvae

7

chemical control

insecticides

8

larvicides

insecticides that specifically targets the larval stage of mosquitoes

9

adulticide

insecticides against adult mosquitoes

10

isolation

applies to animals/persons who are known to be ill with contagious disease

11

quarantine

applies to those who have been exposed to a contagious disease

12

protection of portals of entry

personal protection: protective clothing, repellents, nets on doors and windows, mosquito nets

13

chemoprophylaxis

use of antimicrobial drugs

14

immunization

vaccination

15

what is the "where" of immunization?

primarily populations in endemic areas

16

what is the "when" of immunization?

if the disease has a distinct "season", such as seen with Vector-borne agents, immunization just before the season will provide the maximum efficiency; outbreak of an nonendemic disease occurs

17

what is the "who" of immunization?

population at risk

18

what is the "why" of immunization?

for a program of vaccination to be justifiable, the loss caused by the disease must be greater than the cost of immunization

19

herd immunity

form of immunity that occurs when the vaccination of a significant/large portion of a population (or herd) provides a measure of protection for the small number of individuals who have not developed immunity

20

OIE steps for establishing a disease control program

establishing rationale, strategic goal and objectives, program planning, implementation, monitoring, evaluation and review

21

WAHID

World Animal Health Information Database

OIE

23

national labs

have unique resources to handle highly infectious agents and the ability to identify specific agent strains

24

reference labs

can perform tests to detect and confirm the presence of a threat agent. These labs ensure a timely local response in the event of a threat incident

25

sentinel labs

represent the thousands of hospital-based labs that are on the front lines. They have direct contact with patients

26

DIVA

differentiating infected from vaccinated animals

27

traceability

facilitates the identification of affected animals, herds, or flocks

28

infected premises

premises where a presumptive positive case or confirmed positive case exists based on laboratory results, compatible clinical signs, case definition, and international standards

29

contact premises

premises with susceptible animals that may have been exposed to the FAD agent, either directly or indirectly, including but not limited to exposure to animals, animal products, fomites, or people from infected premises

30

infected zone

zone that immediately surrounds an infected premises

31

buffer zone

zone that immediately surrounds an infected zone

32

control area

consists of an infected zone and a buffer zone

33

surveillance zone

zone outside and along the border of a control area

34

free area

area not included in any control area

35

vaccination zone

emergency vaccination zone classified as either a containment vaccination zone (typically inside a control area) or a protection vaccination zone (typically outside a control area) this may be a secondary zone designation

36

zoonosis

transmission of infectious diseases from animals to humans

37

what is included in the one health triad?

healthy people, healthy environment, healthy animals

38

GLEWS

the global early warning system for major animal diseases including zoonoses
