Epidemics & Pandemics
100

A field of science that studies health problems within populations

What is Epidemiology? 

100

Factors include host, agent, environment, and time

What is the Epidemiological Triangle?

100

A person who has been exposed to and harbors a pathogen and who has done so for some time

What is an active carrier?

100

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

What is direct transmission? 

100

This occurs at irregular intervals, in a scattered and isolated manner and without geographical concentration

What is sporadic? 

200
This type of study is performed on cells and in test tubes

What is in vitro?

200

This shows the process through which infectious disease transmission occurs

What is the chain of infection? 

200

A person who harbors a pathogen who is also in the recovery phase of the course of the disease but is still infectious.

What is a convalescent carrier?

200

when an agent is transferred or carried by some intermediate item, organism, means, or process to a host, resulting in disease

What is indirect transmission?

200

This belongs to a particular person or population. It means "native to" or " natural to." Usually happens at a low level in a population within the confines of a geographical region. 

What is endemic? 
300

This type of research is done on animals

What is in vivo? 

300

This requires behavior change in the individual

What is active primary prevention? 

300

A person who has been exposed to and harbors a pathogen but has not become ill or shown any of the symptoms of the disease

What is a healthy carrier?

300

droplets or dust particles carry the pathogen to the host and cause infection

What is airborne transmission? 

300

This is more than an expected increase in the number of endemic cases. But can also be a single case in a new geographical area. Can be turned in to an epidemic if not controlled. 

What is outbreak?

400

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

What is a case?

400

The pathogen or disease-causing agent enters the body through this

What is the portal of entry?

400

Someone who has been exposed to a pathogen, is in the beginning stages of the disease, is displaying symptoms, and also has the ability to transmit the disease

What is a incubatory carrier?

400

an arthropod such as a mosquito, flea, tick, or lice conveys the infectious agent (responsible for carrying the disease) 

What is vector-borne transmission? 

400
A generally sudden increase in the number of cases of disease above the normally expected level within a community, population, or region. 

What is an epidemic?

500

an inanimate (nonliving) object such as a piece of clothing, a door handle, or a utensil that can harbor an infectious agent and is capable of being a means of transmission

What is fomite?

500

limiting any disability by providing rehabilitation when a disease, injury, or disorder has already occurred and caused damage

What is tertiary prevention? 

500

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

What is a intermittent carrier?

500

an inanimate object that conveys an infectious agent to a host such as sharing drinking water or in swimming pools, etc. 

What is vehicle-borne transmission? 

500

This spreads over multiple countries or continents and affects a large number of people.  

What is a pandemic?
