characteristics of infectious disease Correct answer--disease
-infection
-signs and symptoms
-syndrome
-signs and symptoms help direct towards diagnosis
-some patients are asymptomatic/subclinical = only signs can be observed thru correct testing
*ex: patient w/herpes and no symptoms
disease Correct answer--a condition where normal structure and/or function are
damaged or impaired
infection Correct answer--invasion of pathogen or parasite that lead to disease
-evidence for infection comes from signs and symptoms
signs Correct answer--things that can be directly measured by clinician

communicable disease Correct answer--capable of spreading person-to-person
(contagious - easily spead)

non-infectious disease Correct answer--disease not caused by pathogen
periods/stages of disease Correct answer--infectious disease follow 5 stages
1. incubation
2. prodromal
3. illness
4. decline
5. convalescence
incubation stage of disease Correct answer--initial entry of pathogen
-replication begins
prodromal stage of disease Correct answer--replication continues
-host shows signs and symptoms
illness stage of disease Correct answer--signs and symptoms are most severe in host
decline stage of disease Correct answer--pathogen number start to decrease
-host's immune system is weak and vulnerable to secondary infection

acute disease Correct answer--relatively short
-hours, days, week
chronic disease Correct answer--longer time

-pathogen replicates when disease is active
Koch's postulates Correct answer--set of standards that must be met to demonstrate that

-developed 1884 and still used today
