Review of Communicable Disease Flashcards
It is a CONTAGIOUS DISEASE and readily transferred from one infected person to a susceptible and uninfected person and maybe caused by microorganism
Communicable Disease
Developing for a short period of time
Acute Disease
Acquired by a person for a long period of time
Chronic Disease
Remains inactive in the body but when the time comes that the person is immunocompromise, the inactive disease may develop
Latent disease
Infections that develop after a prior infection
Secondary Infections
presence of bacteria in the blood
Bacteremia
poisoning of the blood
Septicemia
WBC are the soldiers of the body (True or False)
True
toxins in the blood
Toxemia
virus in the blood
Viremia
Occasional cases
Sporadic Disease
Is always present in a certain area or 4egion
Endemic
sudden increase in the number of cases of disease
Epidemic
Worldwide outbreaks
Pandemic
Number of infected people during a particular time period (i.e. year)
Incidence
Number of disease people at any given time
Prevalence
Measurable changes (Signs or Symptoms)
Signs
Patient Complaint (Signs or Symptoms)
Symptoms
Study of disease
Pathology
Cause of disease
Etiology
Disease process
Pathogenesis
Colonization by microbe
Infection
Organism with potential to cause disease
Pathogen
Pathogen is growing in or on host
Infection
Degree or intensity of pathogenicity
Virulence
Ability of pathogen to spread to other tissues in body
Invasiveness
Ability of pathogen to establish infection
Infectivity
Ability of pathogen to secrete toxins
Toxigenicity
Infection in which pathogen grows massively in the body, being found in blood and throughout organs
Septicemia
Developed in late 1800’s, provide basic logical proof that disease is caused by a microbe
KOCH’S POSTULATES
Microbe must be present in every case of disease, but present also from healthy individuals ( True or False)
False (Microbe must be present in every case of disease, but ABSENT from healthy individuals)
Suspected microbe must be isolated from diseased host and grown in culture (True or False)
True
Different disease must result when isolated microbe is introduced into healthy host (True or False)
False (SAME disease must result when isolated
microbe is introduced into healthy host)
Same microbe must be isolated again from second diseased host (True or False)
True
