Levels of Prevention
100

A field of science that studies health problems within populations

What is Epidemiology

100

“Outbreak” of an illness specifically health-related events in the community or region 

What is epidemic? 

100

First case of disease within the population

What is Primary case? 

100

An object that consist of a door handle, clothing or utensil that is capable of transmission 

What is Fomite

100

Taking actions to prevent a disease or disorder before it happens 

What is Primary prevention? 

200

Ability for a program to benefit people to those who are offered

What is effectiveness? 

200

Epidemic that affects the whole population 

What is pandemic

200

A person that is identified as having a disease, disorder, injury or condition within the population 

What is Case? 

200

Habitat where the infectious agent lives and grows 

What is Reservoir? 

200

Requires “behavior change” from the individual 

What is active primary prevention? 

300

Ability for a program to create desired effect within those who do and don’t participate 

 

What is Efficacy 
300

Disease that is commonly known and constant within the community 

What is Endemic

300

One who is infected with the disease from a population that was in contact with primary case

What is Secondary case? 

300

Invertebrate animals that transports an infectious agent from one host to another 

What is Vector? 

300

Doesn’t require behavior change on the individual 

What is passive primary prevention? 

400

Process of identifying cause of health issue through testing hypotheses

What is Analytic Epidemiology

400

Appears from a specific source 

What is common-source epidemic? 

400

Person with signs and symptoms of a existing or non diagnosed disease 

What is Suspect case? 

400

Infectious organism such as vertebrate animals that transmit to humans through direct contact 

What is Zoonosis? 

400

Identifying disease from health screening and detection activities 

What is secondary prevention? 

500

Portrays the distribution of health issues visually 

What is Descriptive Epidemiology 

500

Infections that is transmitted from one infected person to the other

What is propagated epidemic? 

500

Epidemiology who brings the attention of the first disease case

What is Index case? 

500

Non-living intermediary like famine, food or water that transports the infectious agent from the reservoir to susceptible host

What is Vehicle? 

500

Prevent disability by creating rehabilitation with an existing disease, injury, or disorder 

What is Tertiary prevention?
