Endemic - ANS Diseases that are always present in a population (e.g., colds
and pneumonia)
Epidemic - ANS Diseases that are not always present in a population but flare
up on occasion (e.g., diphtheria and measles)
Pandemic - ANS The existence of disease in a large proportion of the
population: a global epidemic (e.g., human immunodeficiency virus, acquired
immunodeficiency syndrome, and annual outbreaks of influenza type A)
Chronic vs Acute (prevalence) - ANS chronic always has a higher prevalence
than acute disease
Passive Immunity - ANS - natural contact with antibody
- hep a --) immunoglobin
- through blood or plasma
EXAMPLE: Infant born with temporary antibodies to measles. Temporary or
through colostrum and breast milk
Active Immunity - ANS - Natural contact and infection with the antigen
