Epidemiology
evidence-based study of people or a population that evaluates occurrence,
determinants, distribution, control of health, and disease in a defined human population
Centers for Disease Control and Prevention (CDC)
national (U.S.) agency for developing and carrying out disease prevention and control,
environmental health, and health promotion and education activities
Atlanta, GA
World Health Organization (WHO)
International counterpart to CDC
Geneva, Switzerland
John Snow
first epidemiologist who studied cholera between 1849 and 1854
unwashed hands and shared food spread disease
Outbreak of 1849
supported the germ theory of disease (Pasteur and Koch's impact would not be realized
until the 1860s)
Broad Street Water Pump
source of the cholera outbreaks due to sewage contamination
Robert Koch
identified Vibrio cholerae as the causative agent of cholera
Sporadic
occurs occasionally or at irregular intervals in a population
Endemic
maintains a steady, low-level frequency at a moderately regular interval
Ex. Flu
Hyperendemic
, disease gradually increases in frequency beyond the endemic level, but not to an
epidemic level
Ex. common cold during winter months
Outbreak
sudden, unexpected occurrence of a disease, usually in a limited segment of a
population
town/building
Epidemic
outbreak affecting many people at once
country
Pandemic
increase in disease occurrence within a large population over at least two countries
around the world
multiple countries
Normal Prevalence of a Given Disease
determined through epidemiological studies and monitoring
Public Health Surveillance
Incidence
measures the occurrence of new cases of a disease during a defined time period as
compared to the total population
Prevalence
total number of individuals infected in a population at a specific point in time, no
matter when the disease began
Mortality Rate
ratio of the number of deaths from a given disease in the total healthy population
Case-Fatality Rate
ratio of the number of deaths from a given disease to the total number of cases of the
disease
Infectious Disease
results from an infection by microbial agents such as viruses, bacteria, fungi, protozoa,
and helminths (worms)
Communicable Disease
an infectious disease that can be transmitted from person to person
not all infectious diseases are this (rabies)
Herd Immunity
most of the population is immune thus protecting the others of the population who are
not immune
Efforts that Prevent/Control Epidemics
vaccination and immunization
Common risk factors - ANSWER ✅✅✅✅unhealthy diet, physical inactivity, tobacco
use
Childhood risk - ANSWER ✅✅✅✅conditions before birth and early in childhood
influence health in adult life.
