Transmission
the direct and immediate transfer of an agent from a host to a susceptible host
what is direct transmission?
individual exposed to an who harbor a pathogen, are in the beginning stages of the disease
what incubatory carrier?
effort to prevent a disease or disorder before it happens
what is primary prevention?
a person who has been diagnosed with a health related state or event
what is a case?
when there is an increase of the number of cases of a disease that is higher than what is normally expected
what is an epidemic?
transfer of a pathogen to a susceptible host by a vector
what is biological transmission?
individual who has been exposed to and harbors a disease causing organism
what's an active carrier?
activities aimed at early detection to improve the likelihood of cure or reduce the chance of disability
what is secondary prevention?
it is the first disease case in the population
what is a primary case?
an epidemic affecting or attacking the population
what is a pandemic?
disease that results when an agent is transferred or carried by some intermediate item to a susceptible host
what is an indirect transmission?
individuals 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 a healthy carrier?
efforts to limit disability by providing rehabilitation where disease has occurred and caused damage
what is tertiary prevention?
the people who have become infected from the person who had the disease from the primary case
what is a secondary case?
the ongoing or constant presence of a disease in a community
what is an endemic?
vector borne disease transmission processes that occur when the pathogen, in order to spread, uses a host
what is a mechanical transmission?
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?
behavior change from the individual that prevents a disease or disorder happening
what is active primary prevention?
an individual who has all the signs and symptoms of a disease but has not been diagnosed as having it
what is a suspect case?
epidemics that arise from a specific source
what is a common source?
transfer of bacteria or viruses that may become aerosolized when individuals, sneeze, cough, laugh, or exhale
what is airborne transmission?
individual who has been exposed to and harbors a pathogen and who can spread the disease
what is an intermittent carrier?
does not require behavior change from the individual in order to prevent a disease occurring
what is passive primary prevention?
the first disease case brought to attention of the epidemiologist
what is index case?
epidemics that arise from infections transmitted from one infected person to another
what is propagated?
