Car Broken
Uninterrupted and immediate transfer of of infectious agents
Direct Transmission
Infectious agent->Reservoir->Portal of Exit->Mode of Transmission->Portal of Entry->Susceptible Host->
Chain of Infection
Occurrence of illness in excess of normal expectancy within community or region
Epidemic
First disease case within population
Primary Case
Inanimate, nonliving, object that harbor infectious agents which are capable for means of transmission
Fomite
Transfer of agent by means of of carry by object, means or process
Indirect Transmission
Behavior change in individual to prevent infection or disease
Active Primary Prevention
Epidemic that affects or attacks an extensive region, country or continent
Pandemic
Individual or group that all present signs or symptoms but have not been diagnosed
Suspect Case
invertebrate animal that transmits infections by conveying the infectious agent from one host to another
Vector
Pathogen undergoes changes as part of lifestyle within host before being transmitted
Biological Transmission
Means for pathogen or diseased agent to enter the body
Portal of Entry
Aims to describe the distributions of disease and determinants.
Descriptive Epidemiology
First case brought to the attention of epidemiologist
Index Case
Individual that has been exposed and harbors the disease causing organism and has done so for some time
Active Carrier
Inanimate object conveying infectious agent to a new host
Vehicle-borne Transmission
Limiting disability by providing rehabilitation after damage has already occurred due to disease, injury or disorders.
Tertiary Prevention
Focus on the causes and effects or how and why within epidemiology
Analytic Epidemiology
Result of becoming infected by contact with the primary case
Secondary Case
Individual who has been exposed to and harbors the pathogen, is in beginning stages and displaying symptoms. This individual can transmit the disease.
Incubatory Carrier
Occurs when arthropod transfers infectious materials to new host
Vector-borne Transmission
Change that is not behavioral to prevent infection or disease
Passive Primary Prevention
Victims of a common-source epidemic have person-to-person contact with others and spread disease
Mixed Epidemic
Model used to show interaction and interdependence of the agent, host and environment
Epidemiology Triangle
Individual who has been exposed and harbors pathogen. Can spread the disease in different places or at different intervals.
Intermittent Carrier
