Cases
Transmission
General
100

Behavior change on the part of the individual that prevents a disease or disorder before it happens 

Active Primary Prevention 


100

See healthy carrier

Passive Carriers

100

A person who has been diagnosed with a health related state or event 

Case

100
Different ways in which disease is transferred

Modes of Disease Transmission

100

An epidemic affecting or attacking the population of the extensive region, country, or continent

Pandemic


200

Does not require behavior change on the part of the individual to prevent a disease or disorder from occurring 

Passive primary prevention

200

an individual who has been exposed to and harbors a disease causing organism and who has done so for some time, even though he or she may have recovered from the disease 

Active Carrier

200

The first disease case in the population

Primary case

200

Vector-borne disease transmission processes that occur when the pathogen, so as to spread, uses a host as a mechanism for a ride, for nourishment, or as part of a physical transfer process

Mechanical Transmission

200

When an increase in the number of cases of disease occurs above what is normally expected for a given time and place

Epidemic

300

Efforts to limit disability by providing rehabilitation where disease, injury, or a disorder has already occurred and caused damage 

Tertiary prevention 

300

Individual who harbors a pathogen and who although in the recovery phase of the course of the disease, is still infectious

Convalescent Carrier 

300

A person who becomes infected from contact with the primary case after the disease has been introduced into the population

Secondary Case

300

The direct and immediate transfer of an agent from a host/reservoir to a susceptible host 

Direct Transmission

300

The study of the distribution and determinants of health related states or events in human populations and the application of this study to prevent and control of health problems

Epidemiology

400

Activities aimed at health screening and early detection to improve the likelihood of cure and reduce the chance of disability or death

Secondary prevention

400

An individual who has been exposed to and harbors a pathogen; who is in the beginning stages of the disease; who is showing symptoms; and who has the ability to transmit the disease

Incubatory carrier

400

An individual who has all the signs and symptoms of a disease or condition but has not been diagnosed as having the disease or had the cause of the symptoms connected to a suspect pathogen

Suspect case

400

Transfer of a disease to a human by a vector

Vector-borne transmission

400
Provides a description of the who, what, when, and where aspects of health related states or events in a population

Descriptive Epidemiology

500

Effort to prevent a disease or disorder before it happens 

Primary prevention

500

Individual who has been exposed to and harbors a pathogen and who can spread the disease at different places or intervals 

Intermittent carrier

500

The first disease case brought to the attention of the epidemiologist 

Index Case

500

Transfer of a pathogen to a susceptible host by a vector, with the pathogen undergoing reproduction, development changes, or both while in the vector 

Biological transmission

500
Study that involves answering the questions why? and how? These questions are addressing using hypothesis about relationships and statistical tests for assessing the hypothesis. A comparison group is involved. 

Analytic Epidemiology
