a pathogen-carrying organism, usually a person or an animal
what is a host?
a person who has been diagnosed with a medical condition
what is a case?
the method through which the disease spreads to a new host
what is the modes of transmission?
preventing a disease before it happens
what is primary prevention?
the field of medicine that studies the occurrence, distribution, and potential control of illnesses and other health-related variables
what is epidemiology?
an infectious or non-contagious power that is harmful to one's health
what is an agent?
the first disease case in a population
what is a primary case?
the transmission of an agent from a reservoir to a susceptible host in a direct and immediate manner
what is direct transmission?
personal change to prevent the disease from happening
what is active primary prevention?
an epidemic that affects or attacks a large region, country, or continent's population
what is a pandemic?
this can travel between an agent and a host, allowing the disease to spread
what is a vector?
once the illness has been introduced into the public, a person who becomes infected through contact with the first case
what is a secondary case?
a disease that occurs when an agent is transmitted to a vulnerable host by some intermediary object, organism, method, or process
what is indirect transmission?
not requiring a personal change to prevent diseases from happening
what is passive primary prevention?
it provides a means of collecting and evaluating such data in order to characterize changes in disease prevalence across people over time and across geographical locations
what is descriptive epidemiology?
a concept for explaining the pathogen and the settings under which it reproduces and spreads
what is the epidemiology triangle?
a person who has all of the signs and symptoms of sickness but has not been diagnosed with it or had the cause of the symptoms linked to a probable infection
what is a suspect case?
transfer of bacteria through the air
what is airborne transmission?
actions aiming at improving the chances of cure and reducing the risk of disability or death through health screening and early detection
what is secondary prevention?
when the number of illness cases rises over what is typically expected during a given period and location
what is an epidemic?
a process of six links
what is a chain of infection?
first case examined by a doctor
what is an index case?
a method of indirect transmission in which the pathogen is transmitted from one reservoir, source, or host to another inanimate intermediary vehicle items
what is vector-borne transmission?
if a sickness, accident, or illness has already happened and caused harm, tries to reduce impairment by offering rehabilitation
what is tertiary prevention?
the focus of the cause-and-effect investigation, or the why and how
what is analytic epidemiology?
