Unit 8 Childhood Communicalbe Diseases Flashcards
Infection
A condition caused my the entry of microorganisms in the hosts body
Pathogen
An organism that causes diseases
Direct Transmission
Contact with the person who is infected. Through saliva.
Indirect Transmission
Come into contact with an object the infected person has touched. This is the most common way communicable diseases are transmitted.
Etiology
Study of causes or origins of a disease. Where did it come from and how.
Epidemiology
The study of the factors that determine and influence the frequency and transmission of the disease.
Incidence
The number of people contracting the disease in given time period.
Prevalence
The number of total cases in a particular time period regardless of when they developed.
Endemic
A continuous incidence expected in an area.
Epidemic
A sudden increase of a disease in an area.
Pandemic
Is a world wide high incidence of a communicable disease.
Sporadic
Disease occurs randomly, there is no pattern to follow.
Vaccine
Commonly used.
Given as a suspended or weaken disease strain that is injected directly into the body.
Forms active immunity.
Toxoid
Modification of a toxin that simulates production of anti-toxins.
Creates active immunity.
Immune Globulin
Solution that contain antibodies from a human or animal that provides passive immunity.
Specific Immune Globulins or Antitoxins
Special preparations from obtained from blood donors selected for their high antibodies of the disease.
Creates passive immunity.
Virulence
Severity of the disease, needs to be harmful to the body
Resistance
Ability of host to fight the pathogen
Immunity
Natural or required to resist infection
Cycle of infection
Chain of infection: all the links in chair need to occur in order to be infected
Incubation Period
Time between the infection and onset of symptoms
Prodromal period
Initial stage of the disease symptoms not severe, host can be infectious.
Illness period
During which the clinical symptoms appear of the disease
Highly infectous
Convalescent Period
Period symptoms begin to fade until the time of recovery
Not infectious
Immunity
The quality of being unaffected by a disease or a pathogen
Natural immunity
Born with a resistance to the disease. It is in our DNA
Acquired immunity
Gained as a result of having the disease
Active Immunity - Longterm
Gained as a result of a vaccine for the diease
Passive Immunity-Short Term
Where we receive antibodies from a person to protect from a disease.
Newborn Immunity
Newborns have passive immunity from their mother so vaccines begin at 2 months of age.
Erythema Rash
Diffused reddened are on the skin
Macule
Circular reddened area on the skin
Papule
Circular reddened area on the skin that is elevated
Vesicle
Circular reddened area on the skin, elevated and contains fluid
Pustule
Circular reddened area on the skin, elevated and contains pus
Scab
Dried pustule that is covered with crust
Pathognomonic
Meaning particular symptom of disease
