What a finished NRS-425 Topic 2 epidemiology paper looks like
The finished example looks unusually plain, because most of its work is definitional. A case definition arrives early and states what counts as a case, how a case is confirmed and over what period, so the numbers that follow mean one thing. Incidence and prevalence are then handled as separate quantities with separate uses: new cases arising in a period against a population at risk, and existing cases at a point against the whole population. Each rate carries its denominator, its multiplier and its time frame in the same sentence as the number. Data sources are named with their collection method, because surveillance data and survey data have different weaknesses. A model of disease causation is applied to the condition, and a short section states what the surveillance system misses.
How an NRS-425 Topic 2 example is structured
The example is built the way a rate is built, from the bottom up. It opens with the condition and why it was selected, then defines a case before quoting any figure at all, since an undefined case makes every later number ambiguous. The population at risk is established next, with its size and its source, because that denominator determines what the paper can claim. Incidence follows, then prevalence, kept in separate sections so their different meanings stay visible, and each is compared against a state or national figure to give it scale. A causation section applies a named model to the condition and identifies where an intervention could interrupt it. The paper closes on limitations: reporting delay, under-ascertainment, changed case definitions over time, and what those do to the figures presented above.
Case definition before any number
What counts as a case, how it is confirmed and over what period are settled first, because every rate in the paper inherits that definition.
Incidence and prevalence kept apart
New cases over a period and existing cases at a point are calculated and discussed separately, since conflating them misstates both risk and burden.
Every rate carries its denominator
The population at risk, the multiplier and the time frame travel with each figure, so a bare count is never presented as though it were a rate.
Data sources named with their method
Registry, surveillance and self reported survey data are labeled as such, because their weaknesses differ and the interpretation has to account for that.
A causation model actually applied
The agent, host and environment or the causal web is worked through for this specific condition rather than defined and then left behind.
Limitations of the count stated
Reporting lag, under-ascertainment and definition changes are named, so the figures are presented with the honesty a rubric line rewards.
Where marks go in NRS-425 Topic 2
The recurring loss on this topic is treating two measures as one word. Using incidence and prevalence interchangeably, or calculating one and labeling it the other, undermines every conclusion built on top and is the first thing a grader checks. Counts presented as rates are the second leak, because four hundred cases means nothing until the population it came from is attached. Missing time frames are a third, since a rate without a period cannot be compared with anything. Papers that describe an epidemiological model without applying it to their own condition lose the application line, and papers with no limitations section leave a criterion sitting empty. The best examples show the arithmetic openly so a reader can follow the figure back to its source.

NRS-425 Topic 2 questions, answered
Do I have to calculate the rates myself?
Check your instructions, because some sections want the calculation shown and others accept published rates with the source cited. Even where published figures are allowed, stating the numerator, the denominator and the period behind them shows you understand what the number is. Where you do calculate, show the arithmetic so a grader can follow it rather than presenting a total alone.
Which condition works well for this paper?
One with published surveillance data at the level you want to write about. Diabetes, hypertension, asthma, opioid overdose, influenza and sexually transmitted infections are all tracked at state and county level, which makes both the rate and a comparison figure obtainable. Rare conditions and very local outbreaks are appealing but often leave you without a denominator you can defend.
What counts as a good data source here?
Agencies that collect the data rather than sites that repeat it. National and state health department surveillance, federal survey programs and county level profiles publish their collection methods, which lets you discuss limitations honestly. News coverage and advocacy summaries can point you toward a figure, but cite the underlying agency for anything the paper actually relies on.
