Transcript of Epidemiology Basics
“The study of the
of health-related states or events in specified populations."
Measurements of Health
Incidence vs Prevalence
Years of Potential Life Lost
Number of NEW cases for a specified time (ACUTE)
Number of TOTAL cases (OLD + NEW) for a specified time (CHRONIC)
Mortality vs Morbidity
Allow us to compare disease and follow trends
2nd study - the 2nd "D"
Asks "Why" = tests hypothesis
Person - Place - Time
Review Week 2
Questions - Media Literacy
Questions - CEL Contract
Questions - other?
Module 3 LO
The 2 D's
So what is Endemic?
Localized (very confined)
2 or more cases
Extends beyond a local community rapidly
# of cases are greater than expected
2002-06 = 16 vs 2007 = 1600+
Person, place and time
Common terms to describe disease trends
Media Literacy Assignment
Levels of Prevention
Delays or prevents the onset of illness or injury - no symptoms
Steps taken to diagnose early before disease becomes severe
Aims at rehabilitation after severe disease
Types of epidemiological studies
# New Cases
Total at Risk
# New + Old Cases
The 1st "D"
Births in Utah
17.6 = Utah
12.5 = US
Rates are per 1,000 residents

Classification of Disease
Caused by a specific agent/toxin that CAN be transmitted
Chain of Infection
Disease that CANNOT be transmitted
These deplete resources FAST!
