EPIDEMIC LENS / STARTER WEB GUIDE

Read the evidence.
Understand the decision.

A structured way to explore public-health information through signal, evidence, decision, action, and learning.

One subject.
Three learning layers.

Understand

Begin with the population, health issue, place, and period being discussed. Ask what question the material is trying to answer.

Apply

Examine the method, measures, assumptions, and the decision they are intended to inform.

Extend

Follow the original references, note limitations, and identify questions for further learning or professional supervision.

01 / Signal

What first drew attention to the issue? Identify the source, date, setting, and population. Avoid treating an isolated story as a complete picture.

02 / Evidence

Where did the information come from? Separate reported observations, counts, rates, estimates, models, and interpretations. Look for the denominator, comparator, and stated uncertainty.

03 / Decision

Which decision is being considered, by whom, and with what constraints? Distinguish the evidence from the judgement used to act on it.

04 / Action

What action is described, and which authority or institution is responsible? Educational examples do not replace local protocols or official instructions.

05 / Learning

What changed, what remains uncertain, and what would need updating? Keep publication dates and corrections with your notes.

An inspectable
evidence trail.

Prioritise the relevant health authority, official surveillance reports, primary documents, and research suited to the question. Record the publisher, link, publication date, and date accessed. Check consequential claims across credible sources where feasible.

For active health emergencies or personal medical questions, use the relevant official health authority and appropriate professional care. This starter web guide is educational; it is not a clinical tool, an operational protocol, or the completed downloadable Field Guide.
