A field of science that studies health problems within populations.

What is Epidemiology?

100

Occurs when pathogens are transferred between individuals without a contaminated intermediate person, object or environmental surface.

What is a Direct contact transmission?

100

Agent or germ, that causes diseases.

What is a pathogen?

100

Intervening before health effects occur.

What is Primary prevention?

100

The first disease case in the population.

What is a primary case?
200

Something that belongs to a particular people or country.

What is an Endemic?

200

Transmission over distances greater than one meter.

What is Airborne transmission?
200

The habitat in which the agent lives, grows, and multiplies.

What is a reservoir?

200

Screening to identify diseases in the earliest stages, before the onset of signs and symptoms.

What is secondary prevention?

200

The first disease case brought to the attention of the epidemiologist.

What is an index case?

300

An epidemic that is spread over multiple countries or continents. 

What is a Pandemic?

300

Occurs through contaminated materials such as food, clothes, bedding and cooking utensils. 

What is vehicle-borne transmission?

300

The manner in which a pathogen enters a susceptible host.

What is a port of entry?

300

Managing disease post-diagnosis to slow or stop disease progression.

What is Tertiary prevention?

300

Persons who become infected and ill once a disease has been introduced into a population and who became infected from contact with the primary case.

What is the secondary case?

400

A disease that affects a large number of people within a community, population or region.

What is an Epidemic?

400

Occurs when the agent is carried by an insect or animal to a susceptible host.

What is vector-borne transmission?

400

The path by which a pathogen leaves it's host.

What is active primary prevention?

400

An individual of group of individuals who have all of the signs and symptoms of a disease or condition yet has not been diagnosed as having the disease.

What is a suspect case?

500

An outbreak in which a group of persons are all exposed to an infectious agent or a toxin from the same source.

What is a Common-Source?

500

The transfer of an infectious agent from a reservoir to a host by suspended air particles, inanimate objects or animate intermediaries. 

What is indirect-transmission?

500

One who harbors a pathogenic organism for a clinically significant time and is able pass the infection to others.

What is an active carrier?

500

Person that is not actively involved.
