Keep That Away
The act of intervening before an infection occurs, such as a vaccine
What is primary prevention?
A person that harbors an agent who may not have an obvious disease
What is a carrier?
Droplets, airborne, and direct contact are all considered
What are modes of transmission?
A disease found in a particular population or area
What is an endemic?
The manner in which a pathogen enters a host
What is the portal of entry?
An individual that could transmit a disease but has no symptoms
An agent spreading through contact or droplets is considered this
What is direct transmission?
A generally sudden increase in the number of cases of a disease above normal levels
What is an epidemic?
The path by which a pathogen leaves the host
What is the portal of exit?
A type of intervention suited for the earliest stages of a disease
What is secondary prevention?
An infected individual that could transmit the disease to others
What is an active carrier?
The transfer of an agent through suspended air particles, vehicles, or other vectors
What is indirect transmission?
An epidemic that has spread across multiple countries or continents and affects a large number of people
What is a pandemic?
The habitat in which an agent typically lives, grows, and multiplies
What is a reservoir?
What is tertiary prevention?
An individual that harbors an infectious agent periodically, not continuously
What is an intermittent carrier?
The transmission of a disease, typically through the use of insects
What is vector-borne transmission?
A type of epidemiology concerned with cause and effect
What is analytical epidemiology?
The first link of the chain of infection
What is the infectious agent?
A set of interventions to reduce disability, and improve functions in individuals with health conditions while interacting with their environment
What is rehabilitation?
An individual that has recovered from an illness, but could still transmit the disease to others
What is a convalescent carrier?
An example of this is a fly contaminating things by landing on them
What is mechanical transmission?
A type of epidemiology aiming to describe the distribution of disease and its determinants
What is descriptive epidemiology?
The final link in the chain of transmission is known as the
