What is an endemic?
Contains, spreads, or harbours an infectious organism.
What is a carrier?
Droplets or dust particles that carry a pathogen to the host and cause infection
What is airborne transmission?
An individual that has been exposed to and carries a disease causing organism - though the individual may have recovered from the disease.
What is an active carrier?
Any virus, bacteria, fungus or parasite that can cause illness to an individual
What is an infectious agent?
Epidemic that has spread over multiple countries
What is a pandemic?
What is a vehicle?
Uninterrupted and immediate transfer of an infectious agent from one person to another. This mode of transmission requires the physical transfer of a pathogen.
An individual that has been exposed or carries a pathogen but has not become ill from it.
Method in which a disease is transmitted
What is a modes of transmission?
The sudden increase in cases of a disease above the normally expected levels in a region
An inter vertebrae animal that transits infection by conveying infectious agents from one host to another.
What is a vector?
Pathogens that are spread by using a host (e.g. fly, flea, or rat)
What is mechanical transmission?
Individual that has been exposed to a pathogen and can spread the disease in different places or at different intervals
What is an intermittent carrier?
What is a reservoir?
What is a propagated epidemic
An inanimate object that can harbour an infectious agent and can assist in means of transmission.
What is a fomite?
An inanimate object that conveys an infectious agent to a host
An individual harbouring a pathogen that is in recovery phase of the disease but still infectious
What is a convalescent carrier?
What is portal of entry?
Characterization of the distribution of health-related state or events
What is descriptive epidemiology?
An infectious organism in vertebrae animals that can be transmitted to humans via direct contact, fomite, or a vector.
What is a zoonosis?
A pathogen undergoing life cycle changes prior to leaving a host through portal of exit.
An individual that harbors a pathogen in the beginning stages of the disease. Individual displays symptoms and can transmit the disease
What is an incubatory carrier?
Pathogen leaving a reservoir through a route like the bodily fluids if the reservoir is human.
