which the Surveillance, Epidemiology, and End Results Program was developed.
SEER collects
cancer data throughout the US.
Q: Uses of Surveillance Information
Answer:
Immediate: epidemics, emerging health problems,
changes in health practices, changes in antibiotic resistance
Annual: estimating magnitude of health problem, assessing control activities, setting
research
priorities, testing hypotheses, etc
Archival: describing natural history of diseases, facilitating epidemiologic and lab
research,
setting research priorities, documenting distribution and spread
