when an infectious agent is transferred by direct contact
What is direct transmission
a person with inapparent infections who is capable of transmitting the pathogen to other hosts
what is a carrier
a set of standard criteria in identifying whether a person has a particular disease, health condition, or syndromes.
what is a case
aims to prevent injury or diseases before it ever occurs
what is primary prevention
an outbreak and infectious disease that's been spread around the world
when an infectious agent from a reservoir to an individual by suspended air particles, inanimate objects, or vectors
what is indirect transmission
a host that's been infected through a pathogen but does not show any symptoms of being infected
what is healthy carriers
only applies to infectious diseases that spread from person to person
what is a primary case
reduces the impact of a disease or injury that has already happened
what is secondary prevention
the ability to produce a an intended result
what is efficacy
describes any size particle capable of travel through the air
what is airborne transmission
those who have recovered from their illness caused by pathogens but remain capable of transmitting to others
what is a convalescent carrier
individuals who contracted the illness through exposure to a primary case
what is a secondary case
aims to focus on people who have already affected by a disease
what is tertiary prevention
the action of restoring someone to what was a healthy and normal life after an individual has gone through imprisonment, addiction, or illness
what is rehabilitation
the transfer of pathogens from an infected host or a contaminated substrate to a susceptible host
what is mechanical transmission
those who can transmit the agent during the incubation period before clinical illness begins.
what is incubatory carrier
the first identified case in a group of related cases of a disease
what is an index case
measures that come before an illness or injury and before the disease process can occur
what is active primary prevention
when there is a path by which a pathogen leaves its host
what is portal of entry
involves survival and reproduction within a parasitized vector
what is biological transmission
hosts who have been exposed to pathogens and spread the disease at different places or intervals.
what is intermittent carrier
might be classified as this when laboratory results are waiting to become available
what is a Suspect case
does not require behavioral change on the part of the individual to prevent a disease or disorder
what is passive primary prevention
when there is a path by which a pathogen enters its host
what is portal entry
