Vectors
Animals that carry pathogens from one host to another.

Mechanical
Biological
Anthropod
Anthropod Vectors
insect vectors
Mechanical vectors
Insect carries pathogen on feet or other body part.
Biological vectors
Insect bites infected person -> pathogens reproduce in the vector -> transmitted to humans by bite or feces while biting.
Epidemiology
(among or upon the people)
The study of disease within a population.
Concerned with collecting data and analyzing data.

Descriptive epidemiology
Concerned with collecting data
Analytical epidemiology
analyzing data
Contract tracing
Causative agents, sources of infection, modes of transmission
Experimental Epidemiology
Test hypothesis such as the effectiveness of a drug.
Case Reporting
Notifiable disease
nationwide
CDC
