The Triangle of Epidemiology
100

preventing a disease or disorder before it happens

What is primary prevention?

100

is the habitat in which an infections agent grows and lives on which it depends for its survival nature 

What is reservoir?

100

individual who has been infected and harbors others for some time , even if the person have recover from the disease 

What is active carrier?

100

immediate transfer of an infectious agent from one person to another 

What is direct transmission?

100

incubation period or life expectancy of the host

What is time?

200

does not require behavior change from the individual

What is passive primary prevention?

200

pathogen enters the body

What is portal of entry?

200

individual who has been exposed and harbors a pathogen, but has not become sick or symptoms 

What is healthy carrier?

200

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

what is airborne transmission?

200

the cause of the diseases 

what is agent?

300

requires behavior change from the individual 

What is active primary prevention?

300

different ways in which disease is transferred 

 what is modes of disease transmission?

300

individual who harbors a pathogen during the recovery phase but still can be infectious 

What is convalescent carrier?

300

an arthropod gives the infectious agent

what is vector-borne transmission?

300

an animal or human that harbors the disease

what is host?

400

limit disability by providing rehabilitation where injury, disease, and disorder has occurred and caused damage

What is tertiary prevention?

400

disease that happens when the pathogen leaves the reservoir through a portal

What is portal of exit?

400

individual who has been exposed and harbors a pathogen and can spread the disease in different places and intervals 

What is intermittent carrier?

400

inanimate object that gives an infectious agent to a host 

what is vehicle-borne transmission?

400

the surroundings and conditions external to the human that cause disease transmission

what is environment?

500

health screening and detection activities used to identify disease 

What is secondary prevention?

500

is human or animal that is susceptible to the disease

what is the host?

500

individual who has been exposed and harbors a pathogen, at the beginning stages of the disease by displaying symptoms, and has the ability to transmit the disease 

What is incubatory carrier?

500

an agent is carried or transferred by a intermediate item resulting in disease

What is direct transmission?

500

organism such as bacteria, fungi, mold , and viruses that is capable of producing disease 

what is pathogen?
