Principles of epidemiology-2 | Nursing homework help

I need these questions answered in 120 words each with individual references

UNIT 1

DQ1

Define endemic, epidemic, and pandemic, and provide an example of each. Describe a current epidemic. Describe one example of each of the prevention types (primary, secondary, and tertiary) that could be applied to control the epidemic.

DQ2

Discuss the role the CDC’s Morbidity and Mortality Weekly Report (MMWR) plays in conveying public health information and recommendations. Describe the type of data and information provided by the MMWR. Choose a report posted within the last 2 years from the “Publications – Weekly Report” tab. Provide a brief summary of the disease report, including the natural history and mode of transmission, and whether the report is an example of descriptive epidemiology or analytical epidemiology.

UNIT 2

DQ1

Disease surveillance is a necessary public health role. Passive surveillance relies on individuals and local authorities “pushing” information to national agencies who then compile, analyze, and disseminate the information. Unfortunately, significant gaps occur in reporting.

Review your textbook, and the CDC’s National Notifiable Disease Surveillance System (NNDSS). Discuss the strengths of the current surveillance systems, the gaps you identified, and why these gaps occur. Discuss the global challenges of coordinating surveillance between multiple countries and provide an example highlighting the challenges. What could other governments and agencies, such as the World Health Organization and the Centers for Disease Control and Prevention, do to strengthen global disease surveillance systems?

DQ2

Explain the importance of validity and reliability in diagnostic testing or research. Describe how validity relates to sensitivity and specificity in diagnostic testing. Identify a health screen specific to a diagnostic test that is currently being debated regarding its use, recommended ages, or frequency, and discuss how validity and reliability play into this debate. What other factors should you consider when you assess the recommendations for a diagnostic test or screen?

UNIT 7

DQ1

Epidemiological methods are used in a variety of public health areas (including infectious disease, chronic disease, and social health) and settings (including the community, schools, and the workplace). Epidemiological methods are used to assess, describe, analyze, and make comparisons of populations to inform evidence-based practices, policies, and interventions. Propose a study based on the methods you have learned thus far designed to investigate an association within one of the public health areas listed (infectious disease, chronic disease, or social health) and the methods you would apply. Discuss and define the risk factor or exposure that is being assessed, the method of comparison that is used, and the setting or situation (community, school, workplace, etc.) your study would look to address. Consider the concepts of causal inference, measures of association, and study design.

DQ2

Race is often used as a descriptor of disease burden and helps us to determine where health disparities exist in order to address them, which is important. It is helpful to differentiate between race as a descriptor and race as a risk factor. Think about institutional racism and its influence on health. Consider the factors related to race and ethnicity that might be influencing disease status more than the genetics of race when answering this discussion question.

Consider the following statement: “Race is not a risk factor and should not be used in public health data collection.” Discuss the ethical and public health implications of this statement. When might collecting data on race perpetuate institutional racism leading to health disparities and when is it necessary to improve public health? Provide support and examples for your answer. Consider ethical issues related to respect for persons, beneficence, and justice as described in “The Belmont Report.”
