Zoonosis

Front 1

acute disease

Back 1

A disease or disorder that lasts a short time, comes on rapidly, and is accompanied by distinct symptoms.

Front 2

Biological vector

Back 2

an arthropod vector in whose body the infecting organism develops or multiplies before becoming infective to the recipient individual.

Front 3

Chronic Disease

Back 3

a disease that persists over a long period. The symptoms of chronic disease are sometimes less severe than those of the acute phase of the same disease. Chronic disease may be progressive, result in complete or partial disability, or even lead to death. Examples of chronic disease include diabetes mellitus, emphysema, and arthritis.

Front 4

Communicable disease

Back 4

a disease the causative agents of which may pass or be carried from one person to another directly or indirectly

Front 5

contagious disease

Back 5

easiely transmitted communicable diseases

Front 6

direct transmission

Back 6

The immediate transfer of an agent from a reservoir to a suceptible host

Front 7

endemic disease

Back 7

An infectious disease that occurs frequently in a specific geographical locale. The disease often occurs in cycles. Influenza is an example of an endemic disease.

Front 8

enzootic disease

Back 8

conditions affecting animals of a specific geographical area

Front 9

epidemic disease

Back 9

disease with sudden onset and widespread outbreak within a group

Front 10

epidemiology rate

Back 10

factors that determine the frequency and distribution of disease within populations

Front 11

epizootic disease

Back 11

Affecting a large number of animals at the same time within a particular region or geographic area. Used of a disease.

Front 12

fomites

Back 12

an inanimate object (as a dish, toy, book, doorknob, or clothing) that may be contaminated with infectious organisms and serve in their transmission

Front 13

horizontal transmission

Back 13

is the transmission of a bacterial, fungal, or viral infection between members of the same species that are not in a parent-child relationship.

Front 14

incidence

Back 14

the statistic that tells about the general health of a population

Front 15

indirect transmission

Back 15

Epidemiology A nonperson-to-person transmission of an agent–eg, parasite from a reservoir to a susceptible host by suspended air particles or by animate–vector or inanimatex–vehicle intermediaries

Front 16

nfectious disease

Back 16

a disease that is carried by a transmissible agent such as viral bacterial fungal or parasitic organisms

Front 17

latent disease

Back 17

is characterized by periods of inactivity either before signs and symptoms appear or between attacks

Front 18

mechanical vector

Back 18

an arthropod vector which transmits an infective organism from one host to another but which is not essential to the life cycle of the parasite

Front 19

morbidity rate

Back 19

the incidence rate, or the prevalence of a disease or medical condition

Front 20

mortality rate

Back 20

is a measure of the number of deaths (in general, or due to a specific cause) in some population, scaled to the size of that population

Front 21

noncommunicable disease

Back 21

NCD is a disease which is not infectious. Such diseases may result from genetic or lifestyle factors

Front 22

pandemic disease

Back 22

is a worldwide epidemic of a disease in humans

Front 23

panzootic disease

Back 23

(an outbreak of an infectious disease of animals) that spreads across a large region (for example a continent), or even worldwide. The equivalent in human populations is called a pandemic.

Front 24

prevalence

Back 24

total number of cases of the disease in the population at a given time, or the total number of cases in the population, divided by the number of individuals in the population.

Front 25

reservoir

Back 25

an inanimate or animate object that serves as a longterm habitat and focus of dissemination for an infectious agent

Front 26

reverse zoonoses

Back 26

There are also diseases of people which are transmissible to animals

Front 27

sentinel

Back 27

early warning systems, for the community.

Front 28

source of infection

Back 28

an individual or object from which an infections is acquired

Front 29

sporadic disease

Back 29

A sporadic disease is one that occurs only occasionally in a population

Front 30

subacute disease

Back 30

not acute

Front 31

transmission

Back 31

transfer from one animal to another

Front 32

vector

Back 32

an animal (arthropod) that transmitts disease organisms

Front 33

vertical transmission

Back 33

transfer from one generation to another

Front 34

zoonoses

Back 34

a disease that can be naturally transmitted from andimals and humans
