Disease Transmission
immediate transfer of an agent from a reservoir to a susceptible host by direct contact such as mouth, open wounds, touching, kissing, or by droplet spread
What is Direct Transmission?
a prevention that aims to prevent disease or injury before it ever occurs.
What is Primary Prevention?
individuals who have been exposed to and harbor a disease-causing organism and who have done so for some time, even though they may have recovered from the disease.
What is Active Carrier?
virus, bacterium, or other microorganism that can cause disease.
What is pathogen?
a person who has been diagnosed with a health-related state or event.
What is Case?
Transmission of an infection from one person to another through an intermediary agent
What is Indirect Transmission?
prevention that aims to reduce the impact of a disease or injury that has already occurred.
What is Secondary Prevention?
although they are in recovery phase of the course of the disease, are still infectious.
What is Convalescent Carrier?
The route by which an organism is transferred from one host to another
What is Modes of Transmission?
the first disease case in the population.
What is Primary Case?
occurs when bacteria or viruses travel on dust particles or on small respiratory droplets
What is Airborne Transmission?
prevention that aims to soften the impact of an ongoing illness or injury that has lasting effects.
What is Tertiary Prevention?
people who have been exposed but have not become ill or shown any of the symptoms of the disease.
What is Healthy or Passive Carriers?
the means by which an infection is able to enter a susceptible host
What is Portal of Entry?
someone who become infected from contact with the primary case after the disease has been introduced into the population.
What is Secondary Case?
indirect transmission of an infectious agent that occurs when a vector bites or touches a person.
What is Vector-Borne Transmission?
behavior change on the part of the individual that prevents a disease or disorder before it happens
What is Active Primary Prevention?
someone who have been exposed to and harbor a pathogen and who can spread the disease at different places or intervals.
What is Intermittent carrier?
any route which enables a pathogen to leave the reservoir or host
What is Portal of Exit?
the first disease case brought to the attention of the epidemiologist
What is Index Case?
the transmission of pathogens through water, food, and air.
What is Vehicle-Borne 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?
are in the beginning stages of the disease, are showing symptoms, and have the ability to transmit the disease.
What is Incubatory Carrier?
the principal habitat in which a pathogen lives, flourishes and is able to multiply
What is Reservoir?
a person who has all the signs and symptoms of a disease or condition but has not been diagnosed as having the disease
What is Suspect Case?
