Transmission
transfer of a disease to a human by a vector.
What is Vector-Borne Transmission?
effort to prevent a disease or disorder before it happens
What is Primary Prevention?
individual who has been exposed to and harbors a disease-causing organism (pathogen) and who has done so for some time, even though they may have recovered from the disease.
What is Active Carrier?
a person who has been diagnosed with a health-related state or event.
What is a Case?
an infectious organism in vertebrate animals (e.g., rabies, anthrax) that can be transmitted to humans through direct contact, a fomite, or a vector.
What is Zoonosis?
transfer of bacteria or viruses on dust particles or on small respiratory droplets that may become aerosolized
What is Airborne Transmission?
behavior change on the part of the individual that prevents a disease or disorder before it happens
What is Active Primary Prevention?
individual who have been exposed to and harbor a pathogen but have not become ill or shown any of the symptoms of the disease.
What is Health Carriers?
the first disease case in the population.
What is Primary Case?
epidemics that arise from a specific source.
What is Common-Source?
disease that results when an agent is transferred or carried by some intermediate item, organism, means, or process to a susceptible host.
What is Indirect Transmission?
does not require behavior change on the part of the individual in order to prevent a disease or disorder from occurring
What is Passive Primary Prevention?
individual that harbors a pathogen and who, although in the recovery phase of the course of the disease, is still infectious.
What is Convalescent Carrier?
those persons who become infected from contact with the primary case after the disease has been introduced into the population.
What is Secondary Case?
epidemics that arise from infections transmitted from one infected person to another.
What is Propagated?
disease transmission processes that occur when the pathogen, in order to spread, uses a host
What is Mechanical Transmission?
activities aimed at health screening and early detection in order to improve the likelihood of cure and reduce the chance of disability or death.
What is Secondary Prevention?
individual exposed to and who harbor a pathogen, are in the beginning stages of the disease, are showing symptoms, and have the ability to transmit the disease
What is Incubatory Character?
an individual (or a group of individuals) 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 suspected pathogen.
an inanimate intermediate involved in the transmission of a pathogen from an infected person or reservoir to a susceptible host.
What is a Vehicle?
transfer of a disease via a particular vehicle, for example, needle use.
What is Vehicle-Borne Transmission?
efforts to limit disability by providing rehabilitation where disease, injury, or a disorder has already occurred and caused damage.
individual who has been exposed to and harbors a pathogen and who can spread the disease at different places or intervals.
What is Intermittent Carrier?
the first disease case brought to the attention of the epidemiologist.
What is Index Case?
the habitat (living or nonliving) in or on which an infectious agent lives, grows, and multiplies and where it depends for its survival in nature.
What is a Reservoir?
