is the measure of the disability and extent of illness caused by disease.
Prevalence
describes the number of cases of a disease at a given time in a specific population
Incidence
Number of new cases of a disease at a given time in a specified population.
Epidemiology
is the study of occurrence, transmission, distribution, and control of disease.
Etiology
The source or cause of a disease.
Lesion
Any type of damage to cell, organ, tissue
Palliative
Relief of pain, symptoms or stress or serious illness.
Symptomatic
Of relating or based on symptoms
Active immunity
making lymphocytes against the threat
Passive immunity
given antibodies, passive protection against threats

Also known as yuppie flu; immune deficiency low
SCID
develops in the womb, severe lack of lymphocytes
Digeorge syndrome
Hereditary, missing thymus
Hypersensitivity
Over response of immune system
Type I (Anaphylactic)
Antibodies over stimulate mast cells/over release of histamine.
Type II (cytotoxic)
Normal reaction, too many foreign cells in your body.
Type III Immune-complex)
Antibodies are attacking wrong place
Type IV (delayed)
Only reports to sleep & thymus/huge reaction, attacks and releases large amounts of histamine
Ischemia
Lack of oxygen, (reversible)
Infarction
tissue death
Chemotaxis
release chemicals to attract white blood cells
Hyperemia
Increase blood flow
Diapedesis
Movement WBC out of tissue

Spores
Protective shell to protect from a harsh environment
Core
Nucleic acid, protein coat, capsid
Naked virus
Core & protein coat
Enveloped virus

Lytic Cycle
Reproduce and kill host cell.
Biostatics
Slows down any weakened cell in your body.
