H1N1, SARS, and West Nile virus are just a few of the disease outbreaks that the CDC has reported. You have been called upon to lead one of the investigations. Select a disease outbreak for which you will lead an investigation.In a report of 750-1000-words, present the following information:Identify and describe the necessary steps to be taken for an investigation of the disease outbreak.For each of the three prevention levels, provide at least two examples of prevention for this disease.Describe the criteria to be met before screening for this disease.Describe how the effectiveness of the screening program will be evaluated.You are required to use a minimum of three scholarly resources.Prepare this assignment according to the APA guidelines found in the APA Style Guide, located in the Student Success Center.

Asthma episodes or attacks can vary from mild to life-threatening. In 2007, about 7% percent of the U.S. population was diagnosed with asthma and there have been a growing number of new cases since that time. There are several known risk factors identified as triggers of asthma symptoms and episodes, including inhalation of allergens or pollutants, infection, cold air, vigorous exercise, and emotional upsets. There is also growing evidence relating body-mass index to asthma in both children and adults. Design a study to investigate whether there is such an association.Choose a study design and justify the reasons you chose the design over others.Select a statistical measure you would use to describe the association (if there is one) between body mass index and asthma.In addition, address:Subject selectionIssues relating to the measurement of both the exposure and the outcomePotential biases that the study might be prone to, and how they might be handledPossible confounding factors and effect modifiers and how to overcome their effectPresent the information in a 750-1000-word report, using section headings where each requirement is described and justified under each of the following headings: Study Design, Statistical Measures, Subject Selection, and Measurement Issues.Refer to the “Key Elements of a Research Proposal.”You are required to use a minimum of three scholarly resources.Prepare this assignment according to the APA guidelines found in the APA Style Guide, located in the Student Success Center.

For the health indicator selected, the paper should include a discussion on the following:Health ProblemDefinition of the problemDescriptive epidemiology (person, place, time)Etiology (causes, risk factors)Health DisparitiesWhat disparities do we know exist for this disease?Why do these disparities exist?What explanations have been offered or supported?What research questions have not been studied that may provide new, insightful information regarding this health problem?Public PolicyWhy is it an important public health problem?What are some social, political, or economic barriers in our current health care system that impede disease prevention and health promotion for this health problem?How would you educate/disseminate information about this health problem to the public? (target group, financial constraints)How could one of a health administrator/manager’s general policies or policies specific to this health condition impact the health status of the target population?You are required to use a minimum of three scholarly resources.Prepare this assignment according to the APA guidelines found in the APA Style Guide, located in the Student Success Center.
