(Answered) NR503 Week 5 Assignment: Infectious Disease Paper


Infectious disease occurs worldwide and must be addressed just as chronic disease is approached. This assignment will offer the opportunity to explore the various communicable diseases, the epidemiological background data as well as the implications of these infections.

Course Outcomes

Through this assessment, the student will meet the following Course Outcomes.

CO 3:  Identify appropriate outcome measures and study designs applicable to epidemiological subfields such as infectious disease, chronic disease, environmental exposures, reproductive health, and genetics.

CO 6:  Identify important sources of epidemiological data.

Total Points Possible

This assessment is worth 125 points.

Due Date

Submit your file(s) by Sunday, 11:59 p.m. MT of Week 5.


Criteria for Content

Apply the concepts of population health and epidemiology to one of the following infectious diseases:  (Choose one from the following list for your paper.)

  • Zika
  • Salmonella
  • MRSA
  • Clostridioides difficile


Include the following in your assignment:

  • Course content from Weeks 1-5.
  • Analysis of the communicable disease (causes, symptoms, mode of transmission, complications, treatment) to include demographic break down (mortality, morbidity, incidence, and prevalence).
  • Identify and synthesize the determinants of health as related to the development of this disease.
  • Identify and describe all elements of the epidemiological triad: Host factors, agent factors (presence or absence), and environmental factors.
  • Succinctly define the role of the primary care nurse practitioner according to a national nurse practitioner organization (AANP, for example) and synthesize the role to the management of infectious diseases(surveillance, primary/secondary/tertiary interventions, reporting, data collecting, data analysis, and follow-up). This includes the integration of models of practice which support the implementation of an evidence-based practice.  Refer to your course textbook for models of practice examples.
  • A minimum of three scholarly references, research articles, is required. Web sites may be utilized but do not count towards the three scholarly references.  Your course text may be utilized but will not count towards the three scholarly references.


Analysis of MRSA

MRSA is an infection caused by a strain of staph bacteria that is resistant to ordinary antibiotics such as penicillin used in treating staph infection. The symptoms of MRSA depend on the area infected. However, the most common symptoms may include mild infection on the skin such as boil (Hassoun et al., 2017). The infected area may be swollen with red painful bumps similar to pimples. The areas may also contain pus and may be warm to touch. The mode of transmission of MRSA is through direct contact with discharge, wounds and soiled areas. Other risk factors include living in crowded areas especially among hospitalized patients. Given that MRSA infections are resistant to treatment, they may cause severe complication as well as the spread of the infection. These include Necrosis, which is the death of the tissue, nervous system infection, and failure of organs such as the kidney as well as blood poisoning commonly known as septicemia. In regard to treatment, intravenous antibiotics are used to treat MRSA. This is most preferred because they provide more concentration of the medication in the bloodstream. However, oral administration and surgery to drain as well as remove the tissues that are damaged may be used. MRSA is a global health concern. In this view, approximately 94,000 in the US develop MRSA infection while 19,000 dies annually (Health Communities.com, 2019). Given that a good number of patient contracts infection when hospitalized, CDC states that out of 290,000 patients that may be hospitalized, 126,000 infections are caused by MRSA.

The determinant of health as related to MRSA

Identifying social determinants of infectious diseases as increasingly become a concern for public health. In this view, the social determinants of MRSA include lower economic status. As such, Leibler et al., (2017) contend that lower economic status such as low income, overcrowding, homelessness is a risk factor for the development of community Associated-MRSA. MRSA tend to be common and spread faster in a population where there are overcrowding and absence of clean water. As previously stated, the mode of transmission of MRSA is contacted with the wound hence overcrowding is likely to increase development and transmission of MRSA in the community…Please click the icon below to purchase full solution at $10
