Preventions
Behavior change on the part of the individual that prevents a disease or disorder before it happens
Active Primary Prevention
See healthy carrier
Passive Carriers
A person who has been diagnosed with a health related state or event
Case
Modes of Disease Transmission
An epidemic affecting or attacking the population of the extensive region, country, or continent
Pandemic
Does not require behavior change on the part of the individual to prevent a disease or disorder from occurring
Passive primary prevention
an individual who has been exposed to and harbors a disease causing organism and who has done so for some time, even though he or she may have recovered from the disease
Active Carrier
The first disease case in the population
Primary case
Vector-borne disease transmission processes that occur when the pathogen, so as to spread, uses a host as a mechanism for a ride, for nourishment, or as part of a physical transfer process
Mechanical Transmission
When an increase in the number of cases of disease occurs above what is normally expected for a given time and place
Epidemic
Efforts to limit disability by providing rehabilitation where disease, injury, or a disorder has already occurred and caused damage
Tertiary prevention
Individual who harbors a pathogen and who although in the recovery phase of the course of the disease, is still infectious
Convalescent Carrier
A person who becomes infected from contact with the primary case after the disease has been introduced into the population
Secondary Case
The direct and immediate transfer of an agent from a host/reservoir to a susceptible host
Direct Transmission
The study of the distribution and determinants of health related states or events in human populations and the application of this study to prevent and control of health problems
Epidemiology
Activities aimed at health screening and early detection to improve the likelihood of cure and reduce the chance of disability or death
Secondary prevention
An individual who has been exposed to and harbors a pathogen; who is in the beginning stages of the disease; who is showing symptoms; and who has the ability to transmit the disease
Incubatory carrier
An individual who has all the signs and symptoms of a disease or condition but has not been diagnosed as having the disease or had the cause of the symptoms connected to a suspect pathogen
Suspect case
Transfer of a disease to a human by a vector
Vector-borne transmission
Descriptive Epidemiology
Effort to prevent a disease or disorder before it happens
Primary prevention
Individual who has been exposed to and harbors a pathogen and who can spread the disease at different places or intervals
Intermittent carrier
The first disease case brought to the attention of the epidemiologist
Index Case
Transfer of a pathogen to a susceptible host by a vector, with the pathogen undergoing reproduction, development changes, or both while in the vector
Biological transmission
Analytic Epidemiology
