T/F More then 25 million people died during the influenza pandemic of 1918-1919
True
T/F Sometimes notifiable diseases are not reported to the local health department because patients recover- with or without treatment- without a diagnosis being confirmed
True
T/F The average number of years a person from a specific cohort is projected to live from s given point in time is their life expectancy
True
T/F The period of time between exposure to an infectious agent and the onset of symptoms is called the incubation period
True
t/f a primary care physician is concerned with the health of an individual patient, while an epidemiologist is concerned with the health of a population
True
Incidence rates are important in the study of ___ diseases, diseases in which the peak severity of symptoms occurs and subsides within days or weeks
acute
The common cold, influenza, chickenpox, measles, and mumps are examples of
acute diseases
Studies that test hypotheses about relationships between health problems and possible health factors are:
analytic studies
Prevalence rates are useful for the study of ___ disease, diseases that usually last 3 months or longer these cases, it is more important to know how many people are currently suffering such a disease than know when they become afflicetd
chronic
Arthritis, heart disease, cancer and diabetes are examples of
chronic diseases
A type of epidemic where cases are exposed to a common source over time is an:
common source epidemic
When using criteria of causation, the criterion that addresses the issue of whether the association has been reported in a variety of people, has been exposed in a variety of settings, and can have repeatable results by other researchers is
consistency
Studies that seek to describe the extent of disease in regard to person, time, and place are
descriptive studies
Epidemiologists conduct two general types of investigations/studies to better understand how disease is distributed in the population and what determines who gets sick and who does not. What are they?
descriptive studies and analytic studies
A disease that occurs regularly in a population or in a certain location is referred to as a
endemic disease
Studies that are carried out to identify risk factors of a disease or to determine the effectiveness of an intervention are:
experimental studies
What mortality statistics in particular, continues to be used to be the single most reliable indicator of a population's health status
infant mortality
Notifiable diseases, such as ____ diseases that can be epidemic and for which health officials maintain weekly records
infectious
In 1990, the number of YPLL- 75 per 100,000 population was lowest for which two causes of death?
influenza and pneumonia and nephritis (kidney disease)
In 2016, the number of YPLL-75 per 100,000 population was highest for which two causes of death?
malignant neoplasms (cancer) and unintentional injuries.
In 1990, the number of YPLL (years of potential life lost) 75 per 100,000 population was highest for which two causes of death
malignant neoplasms and diseases of the heart
Analytic studies can be either
observational or experimental
Studies that simply observe the natural course of events, taking note of who is exposed or unexposed and who has or has not developed the disease of interest are:
observational studies
An outbreak of disease over a wide geographical area such as a continent or multiple continents is a
pandemic
A type of epidemic where all cases were exposed at a single point in time is a :
point source epidemic
an epidemic curve depicting a distribution of cases traceable to multiple sources of exposure is a
propagated epidemic curve
The number of events of interest that occur in a given population over a given period or at a given point in time is a
rate
According to the chapter, what is the leading cause of death for all age groups between 1-44 years
unintentional injuries
