What is epidemiology?
study of distribution and determinants of disease in populations
What is the purpose of epidemiology?
identify patterns, causes, and guide prevention of disease
Who is the father of epidemiology?
John Snow
What is the historic focus of epidemiology?
Acute illness
Epidemics
What is the current focus of epidemiology?
Chronic disease
Pandemics
Other health-related events
Who was florence nightingale?
Founder of modern nursing; improved hygiene and sanitation.
-First nurse epidemiologist
Nightingales' Coxcomb diagram?
shows preventable deaths go down
What are the three types of epidemiology?
- Descriptive
- Analytic
- Experimental
What is descriptive epidemiology?
Person, Place, Time (Who, where, when?)
What is an epidemic?
a widespread occurrence of an infectious disease in a community at a particular time.
ex. HIV, ebola, measles
,What is an endemic?
diseases that are presented in the population all the time at low levels
ex. heart disease, malaria
What is a pandemic?
worldwide epidemic
ex. covid 19, influenza
5 major factors of epidemiology
• Describes the occurrence of a disease or health disorder
• Distribution—"Who" has the disease, where, when
• Frequency—"How often" were they affected
• Population
• Determinants
What is analytic epidemiology?
examines complex relationships among determinants of disease - investigates
associations between all factors associated with the development of disease
What is a host?
susceptible person or population
What is an agent?
the causative factor that contributes to a health problem
What are the three types of agents?
Infectious agents (bacteria, fungi, etc.)
Chemical agents (pesticides, chemicals, etc.)
Physical agents (exposure to physical elements like radiation, etc.)
What is the environment?
external factors that influence agent and host vulnerability
What is rate in epidemiology?
# of occurrences / total population of interest
What is incidence rate?
# of new case in population at specific time / total population of interest
What is attack rate?
cumulative incidence of infection in a group during an epidemic / number of people
exposed
What is the prevalence rate?
number of existing cases at specific time / population total
What are crude rates?
a rate in which the denominator include the total population
What are age-adjusted rates?
used to make comparison of relative risks across groups and over time when groups
differ in age structure
What is the most reliable measure of population health status?
mortality statistics
What is life expectancy?
average number of years a person from a specific cohort is projected to live
What is cause-specific mortality?
# of deaths for specific disease / total population
What is crude mortality rate?
, # of deaths / total population
What is infant mortality rate?
# infant deaths prior to age 1 / number of live births
What is years of potential life lost (YPLL)?
evaluates the impact of premature death related to specific causes (life expectancy -
age when person dies)
What are working conditions factors?
noise, level of stress, etc.
What is human population distribution?
urban crowding, urban heat island, etc.
What are the two classifications of disease?
1) Acute (<3 months) or Chronic (>3 months)
2) Communicable or Non-Communicable
What is the multi-causation model?
- your genetic endowment
- your personality, beliefs, and behavioral choices
- your environment
What are the links of the chain of infection?
- Agent
- Reservoir
- Portal of exit
- Transmission
- Portal of entry
- Establishment of infection in new host
What are the two types of modes of transmission?
Direct (touching) and indirect (transmission involving an intermediate step)
What is a vehicle-born transmission?
inanimate object (e.g. stuffed animal)
What is a vector-born transmission?
animals or insects
How can you control the agent?
kill the bacteria/disease
How can you eradicate the reservoir?
insecticide for mosquitoes
How can you control the human reservoir?
quarantine
How can you control the portal of exit and entry?
universal precautions or isolation
What is experimental epidemiology?
involves testing a hypothesis concerning the cause of a disease
What is an experimental study?
Treatments and exposures occur in a controlled setting
ex. will a certain drug influence lowering lab value?
What is a cross-sectional study?
examine or surveys exposures and outcomes at one point in time
What are prospective studies?
