Vaccination
4 Targets for Prevention
Infected person, animal or environment

Behavior modification
health edu targeted at general public & high risk groups
ex. sex ed
Immunization
person made immune or resistant to ID (infectious disease)
using vaccine - stimulates body own immune system for protection
Personal protective equipment
equipment that acts as a physical barrier to infections

post exposure prophylactic
Social distancing
to increase distance bt infected and susceptible person
restrictions on social gatherings
ISOLATION
Physical separation of sick
QUARNETINE
Physical separation of EXPOSED
Herd immunity
The presence of a large proportion of immune people in the population that lessens the likelihood that an infected person will come into contact with someone who is susceptible

has a frequency in excess of normal expectancy
Pandemic
very virulent, happens when no herd immunity, all over in large parts of the world, crossing boundaries
