Epidemiology is the study of diseases in given populations. Epidemiologists examine how and where disease outbreaks start, how diseases are transmitted among individuals in a population and how to effectively treat those diseases.
Epidemiology, as defined in this lesson, would include which of the following activities?
Biologically plausible hypothesis Comparison of a health outcome among exposed and unexposed groups Multivariate statistical model Epidemiology questions for public health action Epidemiology questions health surveillance includes which of the following activities: Diagnosing whether a case of encephalitis is actually due to West Nile virus infection Soliciting case reports of persons with symptoms compatible with SARs from local hospitals Creating graphs of the number of dog bites by week and neighborhood Writing a report on trends in seat belt use to share with the state legislature Disseminating educational materials about ways people can reduce their risk of Lyme disease The hallmark feature of an analytic epidemiologic study is: Choose one best answer Use of an appropriate comparison group Laboratory confirmation of the diagnosis Publication in a peer-reviewed journal Statistical analysis using logistic regression A number of passengers on a cruise ship from Puerto Rico to the Panama Canal have recently developed a gastrointestinal illness compatible with norovirus formerly called Norwalk-like virus.
Testing for norovirus is not readily available in any nearby island, and the test takes several days even where available. Assuming you are the epidemiologist called on to board the ship and investigate this possible outbreak, your case definition should include, at a minimum: Choose one best answer Clinical criteria, plus specification of time, place, and person Clinical features, plus the exposure s you most suspect Suspect cases The nationally agreed standard case definition for disease reporting A specific case definition is one that: Is likely to include only or mostly true cases Is considered "loose" or "broad" Will include more cases than asensitive case definition May exclude mild cases Comparing numbers and rates of illness in a community, rates are preferred for: Choose one best answer Conducting surveillance for communicable diseases Deciding how many doses of immune globulin are needed Estimating subgroups at highest risk Telling physicians which strain of influenza is most prevalent For the cruise ship scenario described in Question 7, how would you display the time course of the outbreak?
Choose one best answer Endemic curve Seasonal trend Secular trend For the cruise ship scenario described in Question 7, if you suspected that the norovirus may have been transmitted by ice made or served aboard ship, how might you display "place"?
Age of passenger Detailed food history what person ate while aboard ship Status as passenger or crew Symptoms When analyzing surveillance data by age, which of the following age groups is preferred?
Choose one best answer 1-year age groups year age groups Depends on the disease A study in which children are randomly assigned to receive either a newly formulated vaccine or the currently available vaccine, and are followed to monitor for side effects and effectiveness of each vaccine, is an example of which type of study?Please take the quiz to rate it.
