MODELING EPIDEMIOLOGICAL DYNAMICS UNDER ADVERSARIAL DATA AND USER DECEPTION
Epidemiological models increasingly rely on self-reported behavioral data for forecasting disease transmission and assessing non-pharmaceutical interventions (NPIs). However, this data is often subject to strategic misreporting due to individual incentives (e.g., avoiding penalties, accessing benefits, expressing distrust in public health authorities). This paper introduces a game-theoretic framework, specifically a signaling game, to model the interaction between the population (senders) and a public health authority (PHA, receiver). Individuals report their behaviors (e.g., vaccination, masking), potentially deceptively, and the PHA updates its epidemiological model and adjusts recommendations based on these signals. The framework couples a stochastic compartmental model with the signaling game, allowing the PHA to infer credibility and design effective policies even with adversarial behavioral observations. The research characterizes game equilibrium outcomes (separating, partial pooling, and pooling) and evaluates the degree of deception tolerable while maintaining epidemic control through policy interventions. Findings indicate that separating equilibria, with minimal deception, can drive infections to near zero. Remarkably, even under pervasive dishonesty in pooling equilibria, well-designed strategies can still maintain effective epidemic control. This work provides tools for designing robust public health models in the presence of strategic user behavior.

PHA Issues Recommendations (Adaptive Policy)
The proposed game-theoretic framework models a dynamic interaction. The Public Health Authority (PHA) queries individuals, who may strategically misreport their vaccination or masking status. The PHA then uses these (potentially distorted) signals, alongside observed hospitalization data, to update its epidemiological model and formulate policy recommendations.
| Equilibrium Type | Characteristics | Impact on Epidemic Control |
|---|---|---|
| Separating |
|
Achieves effective epidemic control (Rc < 1) and disease-free equilibrium. |
| Partial Pooling |
|
Can still enforce policies satisfying Rc < 1, but with slower control than separating equilibrium. |
| Pooling |
|
Often fails to reach epidemic threshold within simulation horizon, indicating sustained transmission due to severely degraded information quality. |
The study identifies three main equilibrium types, each with distinct implications for the honesty of reported data and the effectiveness of public health interventions. These equilibria highlight the trade-off between individual incentives and societal health outcomes, demonstrating how the level of deception impacts the PHA's ability to control an epidemic.
Adaptive Policy
Outperforms Random Policy in Epidemic Control
A key finding is that the adaptive, signal-informed policy consistently outperforms a random policy that ignores reported behavioral information. Under adaptive control, the controlled reproduction number (Rc) falls below one more quickly, leading to lower peak hospitalization and rapid gains in vaccination/masking coverage, even with higher early deception rates.
Robustness to Stress Factors
Problem: Epidemiological models face various real-world perturbations. The paper investigates the robustness of the SVEAIR-signaling-game pipeline against stress factors such as infection-hospitalization ratios (IHRs), incentives for vaccination/masking, non-responsive survey shares (NRS), and vaccine efficacy.
Solution: The framework was stress-tested across all equilibrium types. For example, doubling IHR doubles peak hospitalization, but disease control can still improve under pooling. Increases in vaccine efficacy significantly lower peak hospitalization and improve disease control, especially under partial pooling. However, increasing incentives or NRS had smaller effects on control, primarily perturbing how honestly people report.
Outcome: The simulation results indicate that while some factors (like IHR and vaccine efficacy) have direct impacts on disease severity and control, the system's ability to maintain epidemic control, particularly through signal-informed adaptive policies, shows considerable robustness against behavioral reporting perturbations. This suggests that the proposed game-theoretic approach yields models that are resilient to typical real-world data challenges.
To validate the framework's practical utility, comprehensive stress tests were performed. These tests revealed the model's resilience to various perturbations, confirming that adaptive policies can maintain effective control even under significant external pressures and internal behavioral challenges, such as varying levels of deception or changes in infection dynamics.

Implementing AI-Driven Public Health Strategies
A phased approach to integrating game-theoretic AI models into public health decision-making for more robust epidemic control.
Phase 1: Data Integration & Model Calibration
Establish secure data pipelines for self-reported behavioral data (vaccination, masking) and ground truth (hospitalizations). Calibrate the SVEAIR and signaling game models with historical data to establish baseline parameters and simulate various equilibrium scenarios.
Phase 2: Game-Theoretic Policy Design & Simulation
Design adaptive feedback policies that incorporate inferred deception levels. Run extensive Monte Carlo simulations to evaluate policy effectiveness under different behavioral rates and stress factors, identifying optimal intervention strategies that maintain Rc ≤ 1.
Phase 3: Pilot Deployment & Iterative Refinement
Deploy the AI-driven system in a controlled pilot environment. Continuously monitor real-world reported data, adjust model parameters and policy recommendations based on observed epidemiological outcomes and actual behavioral responses. Refine the equilibrium characterization based on empirical feedback.
Phase 4: Scalable Implementation & Continuous Learning
Scale the system across broader populations or jurisdictions. Implement mechanisms for continuous learning, allowing the AI to adapt to evolving disease dynamics, new NPIs, and changing societal behaviors, ensuring long-term effective epidemic control despite strategic user deception.
