Investigate Epidemics
disease found among common people in certain area
what is an endemic?
a person in a population identified with a disease, disorder, injury or condition
what is a case?
general modes of transmission.
what is direct transmission and indirect transmission?
what does the pathogen exit from when it leaves the reservoir?
what is the portal of exit?
preventing a disease or disorder before it happens
what is primary prevention?
a widespread occurrence of an infectious disease in a community at a particular time.
what is an epidemic?
standard criteria that ensures cases are consistently diagnosed
what is a case definition?
uninterrupted and immediate transfer of an infectious agent
what is direct transmission?
where pathogen enters host what does it enter through?
what is the portal of entry?
primary prevention that requires behavior change in an individual
what is active primary prevention?
a disease covering the whole world
what is a pandemic?
first disease case in population
what is a primary case?
when an agent is transferred by an intermediate item, organism, means, host, disease
what is indirect transmission?
what aids in illness of the host?
what is the host having no immunity to pathogen?
does not require behavior change in individual
what is passive primary prevention?
an epidemic that arises from a specific source
what is a common source epidemic?
another word for primary case?
what is an index case?
when droplets or dust particles carry a pathogen to host to cause infection
what is airborne transmission?
occurs when body develops antibodies and antigens in response to invading pathogen
what is active immunity?
aimed at health screening and detection activities used to identify disease
what is secondary prevention?
an epidemic that arises from infections transmitted from person to person
what is a propagated epidemic?
individual who has all signs of disease but has not been diagnosed from suspected pathogen
what is a suspect case?
when an arthropod conveys an infectious agent
what is vector-borne transmission?
when antibodies enter body, such as through placenta into baby from immune globulin injections
what is passive immunity?
consists of limiting any disability by providing rehabilitations when disease, injury or idisorder has already occurred
what is tertiary prevention?
