Nursing research to a communicable disease
Seven content bullets, one shared word budget, and a disease chosen precisely because its numbers misbehave — HIV incidence is falling while its prevalence rises, and a paper that reports a single rate has missed the point of the assignment.
Editorial process

What the HIV epidemiology paper is actually testing
The first sentence sets two tasks and most papers deliver one. You are asked to apply the concepts of epidemiology and nursing research to HIV, and the nursing-research half is the one that quietly disappears: papers describe the virus competently, then never say what the community health nurse's data collection and analysis is actually used to decide. Treat the two as separate obligations and the paper stops reading like a disease encyclopaedia with a nursing paragraph bolted on.
HIV is also the selection that punishes loose measurement language hardest. The brief asks for mortality, morbidity, incidence and prevalence as four distinct things, and for HIV they move in opposite directions: US incidence has fallen (roughly 36,200 new infections in 2018 to 31,800 in 2022) while prevalence has climbed toward 1.2 million people living with HIV, because antiretroviral therapy converts a fatal infection into a survivable chronic one. A paper reporting one undifferentiated "HIV rate" has not merely been imprecise — it has skipped the single epidemiological fact that explains the modern picture, and every later section inherits the error.
The reportability question has a specific right answer that most papers get wrong. HIV is nationally notifiable, but the legal duty runs to your state or local health department, not to the CDC. State law creates the mandate; the health department's onward notification to CDC is voluntary. So the answer is not "report to the CDC within 24 hours" — it is your own jurisdiction's named recipient and timeframe, taken from your state's reporting rule, which is why this sub-question cannot be answered from a national source.
Two model traps sit in the middle of the brief. First, the Communicable Disease Chain and the epidemiologic triangle are different models — six links against three vertices — and the brief names the chain as a resource while explicitly asking you to discuss the triangle. Keep them apart. Second, HIV's environment vertex is not weather, sanitation or vectors. For a bloodborne and sexually transmitted retrovirus with no non-human reservoir, environment means structural conditions: syringe service access, housing instability, incarceration, distance to a prescriber who will start PrEP. Reaching for the vector-borne template collapses the section into content about a different class of disease.
Finally, the question about schools and community notification is a trap with a legal and ethical answer rather than an infection-control one. HIV is not transmitted by casual contact, so exclusion, isolation and community notification are not indicated; what applies instead is standard precautions, confidentiality protection, and education. Recommending containment here contradicts the transmission route you described three pages earlier, and that internal inconsistency is visible to a marker in a way a thin paragraph is not.
Likely learning objectives
- Distinguish incidence, prevalence, morbidity and mortality as four separate measures, and explain why HIV incidence and prevalence in the United States move in opposite directions.
- Apply the epidemiologic triangle to a bloodborne and sexually transmitted agent, treating the environment vertex as structural and social context rather than physical or vector conditions.
- Likely assessed on whether the nursing-research half of the opening sentence is actually delivered — whether the nurse's data collection and analysis is tied to a decision, rather than listed as a set of duties.
- Place the reporting obligation at the correct level of government, naming a jurisdiction's own recipient and timeframe instead of assuming a federal duty.
- Tends to be rewarded when social determinants are argued as mechanisms of exposure and of access to prevention and treatment, rather than presented as a list of domains.
- Ground global claims in a named region or country with cited figures, since a blanket statement that HIV is endemic to Africa is both imprecise and, as written, wrong.
Assignment instructions
Read the full question
Review every instruction before using the planning guidance that follows.
Write a paper (2,000-2,500 words) in which you apply the concepts of epidemiology and nursing research to a communicable disease. Refer to “Communicable Disease Chain,” “Chain of Infection,” and the CDC website for assistance when completing this assignment. Communicable Disease Selection: HIV Describe the chosen communicable disease, including causes, symptoms, mode of transmission, complications, treatment, and the demographic of interest (mortality, morbidity, incidence, and prevalence). Is this a reportable disease? If so, provide details about reporting time, whom to report to, etc. Describe the social determinants of health and explain how those factors contribute to the development of this disease. Discuss the epidemiologic triangle as it relates to the communicable disease you have selected. Include the host factors, agent factors (presence or absence), and environmental factors. Are there any special considerations or notifications for the community, schools, or general population? Explain the role of the community health nurse (case finding, reporting, data collection, data analysis, and follow-up) and why demographic data are necessary to the health of the community. Identify at least one national agency or organization that addresses the communicable disease chosen and describe how the organizations contribute to resolving or reducing the impact of disease. Discuss a global implication of the disease. How is this addressed in other countries or cultures? Is this disease endemic to a particular area? Provide an example. A minimum of three peer-reviewed or professional references is required. Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required. You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes. Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages. Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor. The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.

Structuring seven content areas across 2,500 words
HIV described: agent, transmission, clinical course, current treatment
Cover causes, symptoms, mode of transmission, complications and treatment in one pass, and fix the terminology before anything else: HIV is the retrovirus, AIDS is a stage defined by a CD4 count below 200 cells per cubic millimetre or by an AIDS-defining opportunistic illness. Keep the treatment paragraph current — antiretroviral therapy, viral suppression, PrEP and PEP.
What the assessor is likely looking for
That HIV and AIDS are used as distinct terms throughout, and that treatment is described in terms of viral suppression and undetectable-equals-untransmittable rather than in the terms of the pre-therapy era.
The demographic of interest: four measures that point different ways
Report mortality, morbidity, incidence and prevalence as four separate cited figures with their reporting years, then explain the divergence rather than leaving the reader to notice it. Add the distribution the brief calls the demographic of interest: age, race and ethnicity, transmission category, and region.
What the assessor is likely looking for
That incidence and prevalence are defined and sourced separately, and that the rise in prevalence is explained as a consequence of effective treatment rather than presented as a worsening epidemic.
Reportability: what is notifiable, to whom, and within what window
Answer the brief's three sub-questions in order — yes it is reportable, name the state or local health department as the recipient, and give your own jurisdiction's timeframe from its own reporting rule. Note the two-tier structure that makes this a state question rather than a federal one.
What the assessor is likely looking for
That the duty is placed at state or local level with a jurisdictional rule cited, rather than asserting that clinicians report directly to the CDC.
Social determinants as mechanisms of exposure and access
Take a named framework — the five Healthy People 2030 domains — and for each determinant you use, state the pathway: how it changes exposure risk, or how it changes access to testing, PrEP initiation, and sustained ART. The brief says these factors contribute to the development of the disease, so each paragraph has to end in a causal mechanism.
What the assessor is likely looking for
That every determinant is tied to a specific pathway — exposure, testing, treatment initiation, or retention in care — instead of being listed as a category of disadvantage.
The epidemiologic triangle for a bloodborne, sexually transmitted agent
Set out agent (HIV-1 and HIV-2, and what the brief's phrase 'presence or absence' means for a virus requiring direct fluid exchange), host (immune status, CD4 count, co-infection, adherence, age, behavioural factors), and environment. Argue the environment vertex from structural conditions, since there is no vector and no non-human reservoir available to describe.
What the assessor is likely looking for
That the environment vertex is populated with structural and social conditions specific to HIV transmission, rather than the sanitation, climate and vector content that belongs to a waterborne or vector-borne disease.
Special considerations for the community, schools and general population
Answer this sub-question with what actually applies — standard precautions, confidentiality protections, and education — and state plainly that casual contact does not transmit HIV, which is why exclusion, isolation and community notification are not indicated. Say what the protections are for, not just that they exist.
What the assessor is likely looking for
That the recommendation is consistent with the transmission route established earlier in the paper, since proposing containment for an agent already described as not casually transmitted is an internal contradiction.
The community health nurse, and why demographic data are necessary
Work through case finding, reporting, data collection, data analysis and follow-up as the brief names them, then close the loop the title asks for: say what the collected data is used to decide, and which community-level decision the demographic breakdown makes possible. This is where the nursing-research obligation from the first sentence is discharged.
What the assessor is likely looking for
That data analysis and follow-up are connected to an action — targeting outreach, locating a break in the care continuum — rather than enumerated as tasks the nurse performs.
A national agency, chosen for what it actually does
Name one national organisation and describe its mechanism of impact: funding stream, surveillance function, guideline authority, or service delivery. A federal initiative with named agencies and numeric targets gives you something to evaluate; an organisation that 'provides information' gives you a paragraph of paraphrase.
What the assessor is likely looking for
That the contribution is described as a specific programme, funding mechanism or measurable target that can be assessed, rather than restated from the organisation's About page.
Global implications and the endemicity question
Answer whether HIV is endemic to a particular area using a region and a cited proportion rather than a continent, then give one worked example of how another country addresses it. Handle the brief's word 'cultures' through documented policy, testing coverage and measured stigma, which is what keeps the section evidential.
What the assessor is likely looking for
That the endemicity claim is precise about region and carries a cited proportion, and that the cross-cultural comparison rests on documented practice rather than generalisation about a population.
Finding surveillance data and your state's reporting rule
Recommended databases
- PubMed
- CINAHL Complete
- CDC WONDER
- UNAIDS AIDSinfo
Search sequence
- 1.Start with your own state health department's reportable conditions list and find HIV on it. The recipient and the timeframe are jurisdiction-specific, so no national source can answer that sub-question for you.
- 2.Pull mortality, morbidity, incidence and prevalence from one surveillance source and one reporting year, so the four figures are comparable instead of assembled from different vintages.
- 3.Take global figures from UNAIDS rather than a news write-up, and record the estimate ranges alongside the point estimates — the uncertainty intervals are part of what you are reporting.
- 4.Search CINAHL using the brief's own function words ('case finding', 'contact tracing', 'partner services') rather than 'nursing role in HIV', which returns bedside clinical care and not the population-health function the brief is asking about.
- 5.Check publication dates on anything covering transmission risk or treatment: guidance on PrEP, long-acting injectables and viral suppression has moved enough that a source more than about five years old can be actively wrong rather than merely dated.
- 6.Note that the CDC website the brief directs you to is a professional source, not a peer-reviewed one, and count your three-reference minimum accordingly.
Reference shortlist
These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.
Principles of Epidemiology in Public Health Practice, Lesson 1, Section 10: Chain of Infection
Centers for Disease Control and Prevention (CDC Archive) · 2012
The primary definition of both models the brief conflates — the epidemiologic triad (agent, host, environment) and the six-link chain of infection. Cite it when you set up the triangle section so the two are visibly distinguished. It is a general framework and gives you nothing HIV-specific; the vertices have to be populated from the HIV sources below.
Social Determinants of Health - Healthy People 2030
Office of Disease Prevention and Health Promotion, U.S. Department of Health and Human Services · 2026
The five-domain SDOH framework (economic stability; education access and quality; health care access and quality; neighborhood and built environment; social and community context) to structure that section around a named framework rather than an ad hoc list. It supplies the categories only — the mechanism linking each domain to HIV exposure or treatment access is yours to argue.
U.S. Statistics
HIV.gov, U.S. Department of Health and Human Services · 2026
The domestic figures for the demographic-of-interest section: estimated new infections, people living with HIV, deaths, and the breakdown by transmission category, race and ethnicity, age and region. This is the source that lets you show incidence falling while prevalence rises. It is a professional source, not peer-reviewed.
Legal Authority for Infectious Disease Reporting in the United States: Case Study of the 2009 H1N1 Influenza Pandemic
American Journal of Public Health, 105(1) · 2015
A peer-reviewed source for the point most papers get wrong: states mandate reporting under their police power, while notification onward to CDC is voluntary, and requirements vary between states. Use it to justify why you cite your own jurisdiction's rule. Its case study is influenza, so it supports the legal structure, not any HIV-specific timeframe.
Ending the HIV Epidemic in the U.S. (EHE) Overview
Office of Infectious Disease and HIV/AIDS Policy, U.S. Department of Health and Human Services · 2026
A national response with named agencies (CDC, HRSA, IHS, NIH, OASH, SAMHSA), four defined pillars, 57 priority jurisdictions and numeric reduction targets — which gives the national-agency section something measurable to evaluate instead of a mission statement to paraphrase.
Global HIV & AIDS statistics — Fact sheet
UNAIDS · 2026
The global counts with their uncertainty ranges — people living with HIV, new acquisitions, AIDS-related deaths — for the global-implications section, and the regional tables that let you replace 'endemic to Africa' with a specific region and proportion. Use it for magnitude; it will not tell you how any one country's programme works.
HIV and AIDS
World Health Organization · 2026
The transmission routes, the current treatment position including that people with a suppressed viral load do not transmit HIV sexually, and the share of the global burden in the WHO African Region. Cite it where you need the endemicity claim stated precisely rather than assumed.
Checking the paper before you submit it
Common mistakes
- Reporting one undifferentiated 'HIV rate' instead of four separate measures, and so missing the fact the whole paper turns on — incidence falling while prevalence rises because treatment keeps people alive.
- Answering the reportability question with 'report to the CDC'. The legal duty runs to the state or local health department under state law, and the department's notification to CDC is voluntary.
- Filling the environment vertex of the epidemiologic triangle with climate, sanitation and vectors, which belong to a different class of disease and say nothing about a virus that requires direct fluid exchange.
- Recommending isolation, school exclusion or community notification, having already written that HIV is not transmitted by casual contact.
- Using HIV and AIDS interchangeably, which makes the prevalence and mortality figures incoherent because the two terms count different populations.
- Delivering the epidemiology and dropping the nursing research — describing what the community health nurse does without ever saying what the data she collects is used to decide.
- Listing the five social determinant domains with no mechanism attached, so the section describes disadvantage instead of explaining how it produces exposure or blocks treatment.
- Calling HIV 'endemic to Africa' as a blanket claim, when the burden is concentrated in eastern and southern Africa and the regional share is a figure you can cite exactly.
- Spending 1,200 words on the disease description and 150 on global implications, when seven required content areas have to share 2,000-2,500 words.
- Adding an abstract out of APA habit when the brief states that one is not required.
Submission checklist
- Word count lands between 2,000 and 2,500, with no single content area consuming much more than a fifth of it.
- Mortality, morbidity, incidence and prevalence each appear as a separate cited figure with its reporting year stated.
- The reporting answer names your own state or local health department, its timeframe, and the rule you took both from.
- Every social determinant discussed ends in a stated mechanism: exposure, testing, treatment initiation, or retention in care.
- All three vertices of the triangle are populated, and the environment vertex is structural rather than physical.
- The schools and community answer states that no exclusion or notification is indicated, and says why that follows from the transmission route.
- The community health nurse section covers all five named functions and states what the collected data decides.
- One national agency is named with a specific programme, funding mechanism or target attached.
- The global section names a region and an example country with figures, not a continent.
- At least three peer-reviewed or professional references; APA format, double-spaced, 10 to 12 point type, one-inch margins, and no abstract.
