Concepts of Transmission
100

Any virus, bacteria, fungus, or parasite that can potentially cause an illness or disease

What is a Pathogen?

100

Immediate transfer of a pathogen through physical contact between an infected host and an uninfected host

What is Direct Transmission?

100

Form of screening and detecting diseases to allow early treatment and prevent further severity of disease/illness

What is Secondary Prevention?

100
Contains, spreads, and fosters an infectious agent

What is a Carrier?

100

An inanimate object that can foster an infectious agent and is a possible form of transmission

What is a Fomite?

200

The first case of a disease in a certain population

What is a Primary Case?

200
An agent is passed on from a host to a susceptible host through an item or organism

What is Indirect Transmission?

200

Mode of prevention that does not require an individuals to undergo any behavioral changes 

What is Passive Primary Prevention?

200

Individual that fosters a pathogen and is able to infect others while in recovery

What is a Convalescent Carrier?

200

A nonliving mediator that transfers an infectious agent from its habitat to a susceptible host

What is a Vehicle?

300

Person who gets infected from contact with the primary case after a disease enters a population

What is Secondary Case?

300

An arthropod carriers an infectious agent

What is Vector-borne Transmission?

300

Mode of prevention that requires an individual to undergo behavioral changes

What is Active Primary Prevention?

300
Individual who was exposed and fosters the pathogen but did not become ill or shown symptoms of a disease

What is a Healthy Carrier?

300

Habitat where an infectious agent lives, grows, and reproduces

What is a Reservoir?

400
Standard criteria that makes sure that cases are correctly diagnosed no matter the time and location of diagnosis

What is Case Definition?

400

An inanimate object carries an infectious agent onto a susceptible host

What is Vehicle-borne Transmission?
400

Prevention level that tries to minimize the severity of an illness or disease after it has already been diagnosed

What is Tertiary Prevention?

400

Individual who has been exposed to the pathogen and shows symptoms in the early stages and is able to transmit the disease

What is an Incubatory Carrier?

400

Invertebrate that transmits an infection by transferring the infectious agent from host to host

What is a Vector?

500

The first case of a certain disease that has caught the attention of epidemiologists

What is an Index Case?

500

A pathogen goes through the process of changes in its life cycle while still within the host or vector before being transmitted to a new, susceptible host

What is Biological Transmission?

500

Attempt to increase the productivity and usefulness of an individual

What is Rehabilitation?

500

Individual who has been exposed to and fosters a pathogen and is able to transmit the disease at different times and places

What is an Intermittent Carrier?

500

Infectious host in vertebrate organisms that can be spread to humans through direct contact, a famine, or vector

What is Zoonosis?
