morbidity
illness due to a specific disease or health condition
mortality
deaths from various causes
epidemic
disease occurs in excess of normal expectancy relative to 'usual' frequency of the disease
(within a state, city, or campus)
,infectious (communicable) disease
an illness cause by an infectious agent that can be transmitted from one person to another
(ex: flu)
non-infectious (noncommunicable) disease
an illness caused by a non-infectious agent and cannot be passed person to person (ex:
cancer)
outbreak
a localized disease epidemic (ex: in a town or healthcare facility
endemic
disease exists in a steady-state within a population, comes and goes (ex: common cold)
sporadic
disease that occurs infrequently and irregularly
pandemic
an epidemic on a worldwide scale
, epidemic threshold
the minimum number of cases (or deaths) that would support the conclusion that an
epidemic was underway (based on statistical projections)
3 steps of surveillance
1. systematic collection of data pertaining to the occurrence of specific diseases
2. analysis and interpretation of these data
3. dissemination of disease-related information
(ex: monitoring food or tracking influenza)
John Snow
mapped the occurrence of cholera in London during the mid-19th century and discovered it
was spreading through the water source
disappearing disorders
conditions that were once common but are no longer present in epidemic form.. brought
under control by immunizations, improvement in sanitary conditions, or use of
antibiotics/medication (ex: smallpox, polio, measles)
residual disorders
conditions for which the key contributing factors are largely known... methods of control not
implemented effectively (ex: STIs, tobacco use, infant mortality)
