Interactive tools for teaching public health, outbreak preparedness and response. Each one puts the learner in front of a decision, and then shows them what it cost.
Working under uncertainty, weighing containment against livelihoods and trust, judging when the evidence is strong enough to act: these are the hardest parts of outbreak response, and they are rarely learned well from being told about them. They are learned by deciding under pressure and then living with the result, even when the result is simulated.
If you teach or design training in this field, the tools here are free to use in non-commercial teaching, apart from two that are used by written permission, and most of them can be adapted to a different context, audience or pathogen.
The tools here are proof of concept as much as finished products. Each one started from a specific teaching problem, such as a concept that learners did not grasp from a lecture or a skill that can only be acquired through practice.
They have been used in postgraduate classrooms and professional training settings, and adapted for different regional contexts and audience levels. Many other teaching problems would suit the same approach.
Outbreak Crisis Manager is a decision simulation of the public health response to a novel respiratory virus in one of five fictional regions.
Outbreak Crisis Manager has a single-player edition and a facilitated multiplayer version; the author can be contacted for details or access.
Contact the authorThe simulation runs for six rounds, which follow the outbreak from the first unexplained cases to the end of the emergency. In each round the player selects non-pharmaceutical interventions within a budget, and each intervention has effects on five measures: health, economy, public trust, resources and equity. The five regions differ in population, economy, vulnerabilities and political constraints, and the same intervention therefore has a different effect in each region. Three stakeholder groups make requests with deadlines, and misinformation events occur in some rounds.
The interventions that reduce transmission most also carry the largest economic and social costs, and a response that is sound on the evidence can lose the region's political support.
Regional and pathogen parameters can be adapted to other outbreak scenarios. The engine has been re-themed once, into The Forest Edge.
The Forest Edge is a One Health field investigation simulation in which four sectors (Public Health, Animal Health, Food Safety and Environment) respond to a zoonotic outbreak over six rounds.
The Forest Edge has a single-player edition and a facilitated multiplayer version; the author can be contacted for details or access.
Contact the authorEach sector holds only part of the information, field teams, budget and authority needed to control the outbreak, and confirming the source requires evidence that no single sector can obtain alone: the virus in human samples, the virus in the animal source, and an analytic study. In each round a sector reviews the situation and its own signals, resolves a crisis, allocates field teams and budget to investigations and control measures, and commits its decisions. The round then closes, and the report shows what changed and what the other three sectors did.
In the single-player edition the player holds one sector and the other three are run by the computer. Their leads report what they see and what they intend, and their findings appear on a shared board once they have investigated. Each round one of them makes a request with a deadline, and a request that is met leads to coordination in the following round. Each round's crisis is put to the player by the person who raises it, with three possible answers where the facilitated version offers two, and an answer can also have a consequence a round later. In the facilitated version, run as the scenario Spillover at the Forest Edge, four teams hold the sectors and the facilitator resolves each round on a board visible to the whole room.
IPC in Outbreak Response is a self-paced, scenario-based ward simulation for infection prevention and control nurses and postgraduate students.
The public link is a preview in which scenes 1 to 3 are open; scenes 4 to 8 are available to enrolled students of the MSc programme.
The player takes the role of the IPC lead nurse on a hospital ward and follows an outbreak through eight scenes, from the first ward signal, through preparedness, the response pillars, genomics and global coordination, to recovery. Each decision connects events on the ward to the national and global systems that act on them and return guidance to the bedside. The simulation was developed for the MSc in Infection Prevention and Control at the Alice Lee Centre for Nursing Studies, National University of Singapore.
The Formula Interactive Exercises are seven self-paced decision exercises built on case studies from The Formula for Better Health by Dr Tom Frieden.
Each exercise places the learner in the position of a decision-maker in a documented case from the history of public health and requires a decision to be committed before the reasoning is revealed. The case studies and the teaching content are Dr Frieden's; the contribution here is the exercise design, which turns each case into a sequence of decisions. Each exercise runs in an undergraduate and a graduate mode on the same material and takes about 15 minutes; it can be used on its own or within a course.
Before the Curve is a single-player narrative simulation of the public health response to a drug-resistant respiratory outbreak in a fictional city, with the player as its Director of Public Health. The three acts follow the See, Believe and Create framework of The Formula for Better Health.
The city, Meridian, has 600,000 inhabitants, and the player is appointed as the first cases appear in a single working-class district. In the first act, See, the player decides which weak signals to investigate and when the evidence is sufficient to act; in the second, Believe, how to build public and political confidence that the outbreak can be stopped; in the third, Create, how to design a response that is fast and fair, with each part of it assigned to a named person. Each decision is made by playing one card from a hand of options, after which the epidemic curve and the player's standing with the main characters are updated on screen. Decisions cannot be reversed, and their consequences carry through to the end.
Trainee at Outbreaks Central is an investigation game in which the player, a trainee at a public health office, traces a foodborne outbreak using evidence held by four One Health offices.
Trainee at Outbreaks Central has a single-player edition and no multiplayer version; the author can be contacted for details or access.
Contact the authorOver one in-game week, three people are infected through food, each by a different route, and the player investigates each infection as a separate case. The player walks through the town, inspects kitchens, interviews residents, submits samples to a laboratory that processes four a day with a turnaround of about four hours, and assembles evidence held separately by four offices. An investigation closes when its case file is answered correctly, and the week ends with a debrief that reviews the three cases and lists every finding, including those the player missed.
Officer of Block 404 is an investigation game in which the player, the newly appointed officer of a public housing estate, establishes how a cluster of leptospirosis arose among the people who live and work there.
Officer of Block 404 has a single-player edition and no multiplayer version; the author can be contacted for details or access.
Contact the authorOver one in-game month, three people on the estate fall ill, and for each of them the player reconstructs the exposure that caused the infection, including where and when it occurred. The player walks the estate, inspects its shared spaces, interviews residents and workers and sends samples to a laboratory. Most of the repairs that would prevent further cases are the responsibility of four other offices, and each office has to be shown the evidence for its part. Time runs while the player moves about the estate, and it stops whenever a screen of text is open.
Movid-26 is a negotiation simulation for teaching global health diplomacy, in which five parties negotiate the allocation of a scarce medicine during a fictional outbreak.
Movid-26 has a single-player mode and a facilitated multiplayer version; the author can be contacted for details or access.
Contact the authorThree states, an international organisation and a manufacturer meet five times over the course of the outbreak, and an epidemic model runs on what they agree. The parties' combined requirements exceed the available supply, so a table that only divides what is available ends with every party below its requirement and the outbreak still in progress.
Each round is anchored to a provision of the International Health Regulations, and the dilemma of the round is the one that provision creates. Participants weigh their parties' interests against legal obligations under time pressure, and no party holds the full information.
The same approach applies wherever a learner needs judgement rather than recall, and the following problems in public health training would suit it.
Presenting accreditation standards to health workers as an interactive sequence of decisions, in place of a checklist or manual.
Orienting new staff to outbreak protocols and institutional systems through scenario-based exercises that develop judgement as well as familiarity.
Designing messages for audiences with varying levels of trust, at different stages of an outbreak, with feedback that shows the consequences of each choice.
Cross-sectoral teams managing other zoonotic spillover events, with mechanics that represent the human-animal-environment interface in operational terms.
Building a sentinel network under resource and time constraints, with competing priorities that require trade-offs.
Translating outbreak modelling outputs and epidemiological evidence into decision-relevant formats for non-technical audiences.
Teaching epidemic dynamics to younger or non-specialist audiences through simulations that are simplified but keep the structure of the underlying model.
Proposals in outbreak preparedness or in another field of public health education are welcome.
