Epidemiology And Human Behaviour Flashcards
-It is the study of the distribution and determinants of diseases and injuries in human populations
-studies the patterns of disease occurrence in human populations and the factors that influence this pattern.
Epidemiology
Unexpected INCREASE IN THE NUMBER of DISEASE CASES in a SPECIFIC geographical area.
Epidemic
Disease outbreak that SPREADS ACROSS COUNTRIES or continents
Pandemic
A disease outbreak when it is consistently present but LIMITED TO A PARTICULAR REGION
Endemic
What is the goal of epidemiology
The ultimate goal is to use this knowledge control and PREVENT THE SPREAD OF DISEASE
Used to test hypothesis, require more resources and specialized knowledge
Analytical studies
Examine patterns of occurrence. Focus on place, person and time. Use relatively accessible data
Descriptive studies
It is the number of events in a given population over a specific period or at a guven point in time
Rates
The average annual number of births during a yr per 1000persons in the population at the mid yr
Crude birth rate
The number of new cases of a disease in a population at risk in a given time period
Incidence rate
The total number of cases of disease existing in a population
Prevalence rate
The proportion of those who became ill after specified exposure
Attack rate
The proportion of persons with a particular condition who die from that condition. The denominator is the number of incident cases; the numerator is the number of cause specific deaths among those cases
Case fatality rate
A policy which means thata even if a community has no reported case of any of the notifiable diseases or events, the health workers still have to report it as “zero case*
Zero cause reporting
It measure of the burden of disease and it reflects to the total amount of healthy life lost
DISABILITY ADJUSTED LIFE YEARS (DALYs)
Refers to the number of years a person lives
Life span
Refers to the number of yrs a person is EXPECTED TO LIVE from a specified starting point
Life expectancy
Field health service information system or FHSIS is example of
