The occurrence of of cases of an illness, specific health-related events. 

What is epidemic?

100

A person in a population who has been identified as having a particular disease, disorder, injury or condition.

What is a case?

100

An inanimate object capable of being a means of transmission.

What is a fomite?

100

The uninterrupted and immediate transfer of an infectious agent from one person to another.

What is direct transmission?

200

Characterization of the distribution of health related states or events.

What is Descriptive epidemiology?

200

A epidemic that affects or attacks the population of an extensive region, country or continent.

What is a Pandemic? 

200

The first one brought to the attention of the epidemiologist.

What is index case?

200

Invertebrate that transmits infection by conveying the infectious agent from one host to another.

What is a vector?

200

Droplets or dust particles carry the pathogen to the host and cause infection.

What is airborne transmission?

300

Finding and quantifying associations , testing hypotheses, and identifying causes of health related states or events.

What is analytic epidemiology?

300

Am ongoing, usual, or constant presence of a disease.

What is a Endemic?

300

Any virus, bacteria, fungus, or parasite can be labeled as this.

What is a pathogen?

300

The habitat in or on which an infectious agent lives, grows, and multiplies.

What is a reservoir?

300

Type of transmission that occurs when a arthropod conveys the infectious agent.

What is vector borne?

400

A behavior, environmental exposure or inherent characteristic that increases the chance of developing an adverse health outcome. 

What is a risk factor?

400

The ability of a program to produce a desired effect among those who are participate in the program compared to those who are not?

What is Efficacy?

400

The cause of the disease.

What is an agent?

400

A nonliving intermediary such as a clothing, food, or water that conveys the infectious agent from its reservoir to a host. 

What is a vehicle?

400

Type of transmission that involves an inanimate object that conveys an infectious agent to a host.

What is vehicle-borne?

500

" On, upon,or befall"+ "the people"+"the study of"=

What is Epidemiology?

500

This epidemic arises from specific source.

What is Common Source?

500

The incubation period, life expectancy of the host or the pathogen.

What is time?

500

Contains, spreads, or harbors an infectious organism.

What is a carrier?

500

When the pathogen undergoes changes as part of its life cycle while within the host/vector and before being transmitted to the new host.

What is biological transmission?
