Cards

Term
acellular pertussis vaccine
Definition
A vaccine that uses proteins from the microorganism rather than the whole cell to stimulate the process of active immunity.
Term
active immunity
Definition
Stimulation of antibody production without causing clinical disease.
Term
antibodies
Definition
Proteins capable of responding to specific infectious agents; proteins capable of reacting to a specific antigen.
Term
antigen
Definition
A foreign substance that triggers an immune system response.
Term
communicable disease
Definition
An illness that is transmitted directly or indirectly from one person to another.
Term
conjugate vaccine
Definition
A vaccine in which an altered organism is joined with another substance to increase the immune response, such as the pneumococcal conjugate vaccine, meningococcal polysaccharide conjugate vaccine, and Haemophilus influenzae type b (Hib) vaccine.
Term
direct transmission
Definition
Illness passed from one person or animal to another by contact with body fluids.
Term
disease surveillance
Definition
Monitoring patterns of disease occurrence from the cases of infectious and communicable diseases reported by healthcare workers to state health officials.
Term
endogenous pyrogens
Definition
Pyrogens that are released in response to an invasive organism and travel through the circulatory system to the hypothalamus, where they trigger the production of prostaglandins.
Term
herd immunity
Definition
Immunization of healthy children so that pathogens do not have hosts to reproduce and survive, enabling infants not yet fully immunized and children with medical contraindications to immunizations to be indirectly protected.
Term
indirect transmission
Definition
The passage of an infectious disease involving survival of pathogens outside humans before they invade a new host.
Term
infectious disease
Definition
Illness caused by a microorganism that is commonly communicated from one host (human or otherwise) to another.
Term
killed virus vaccine
Definition
A vaccine that contains a killed microorganism that is still capable of inducing the human body to produce antibodies to the disease.
Term
live virus vaccine
Definition
A vaccine that contains the microorganism in a live but attenuated, or weakened, form.
Term
nosocomial infections
Definition
An infection acquired in a healthcare agency, not present at the time of entrance to the agency.
Term
opisthotonos
Definition
Rigid hyperextension of the entire body; hyperextension of the head and neck to relieve discomfort.
Term
pandemic
Definition
The emergency and worldwide spread of an influenza or other viral or bacterial pathogen that causes significantly increased morbidity and mortality.
Term
passive immunity
Definition
Immunity produced through introduction of specific antibodies to the disease, which are usually obtained from the blood or serum of immune persons and animals; does not confer lasting immunity.
Term
phagocytosis
Definition
The engulfment and destruction of microorganisms, dead cells, and foreign particles.
Term
prostration
Definition
Extreme exhaustion, unable to make any effort.
Term
recombinant vaccine
Definition
A vaccine in which an organism has been genetically altered.
Term
toxic appearance
Definition
Lethargy, poor perfusion, hypoventilation or hyperventilation, and cyanosis.
Term
toxoid
Definition
A toxin that has been treated (by heat or chemical) to weaken its toxic effects but retain its antigenicity.
Term
transplacental immunity
Definition
passive immunity that is transferred from mother to infant.
Term
vectors
Definition
Insects or animals that transmit infectious organisms by their biting humans.
Term
zoonosis
Definition
Infectious disease transmitted to humans from an insect or animal host.
