Line list
Wed, Apr 21, 2027 · Week 14 · Biotechnology for Health (Biomedical Innovations)
Today's goal: Build an outbreak line list and calculate incidence and prevalence from case data.
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Line list (one row per case), gastrointestinal outbreak:
- Case 1: onset day 1, symptoms vomiting/diarrhea, outcome recovered
- Case 2: onset day 1, symptoms diarrhea, outcome recovered
- Case 3: onset day 2, symptoms vomiting, outcome still sick
- Case 4: onset day 3, symptoms diarrhea/fever, outcome still sick
- Case 5: onset day 4, symptoms vomiting, outcome still sick
Incidence (new cases) by day: day 1 = 2, day 2 = 1, day 3 = 1, day 4 = 1.
Prevalence on day 4 (all still sick on day 4): 3 cases (cases 3, 4, 5).
Trend observation: New cases appeared every day through day 4, so the outbreak was still ongoing and had not yet peaked.
| Case ID | Onset day | Symptoms | Outcome |
|---|---|---|---|
| 1 | 1 | Vomiting/diarrhea | Recovered |
| 2 | 1 | Diarrhea | Recovered |
| 3 | 2 | Vomiting | Still sick |
| 4 | 3 | Diarrhea/fever | Still sick |
| 5 | 4 | Vomiting | Still sick |
This model shows the level of evidence and organization needed to complete: Completes the Problem 5 line-list step: a case-by-case line list with key fields plus calculated incidence and prevalence and a trend observation.
- Name the variables and include units.
- Enter observations without changing the raw values.
- Check labels, calculations, and patterns before interpreting the data.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: Submit your line list and calculations on Schoology today.
Turn in: Outbreak line list with case ID, onset date, symptoms, and outcome for each case, plus calculated incidence, prevalence, and a written trend observation.

Claim ceiling: Original invented case reports support checked counts, proportions and an observed time-pattern description; they cannot establish any actual outbreak, exposure source, transmission speed, prognosis, intervention effect or official completion.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.

It builds this reusable test skill: Calculating prevalence from a line list.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
