Researchers have developed EpiWorld, a novel framework that integrates large language models (LLMs) with epidemiological world models to improve epidemic intervention policies. This system grounds LLM policy agents in learned, action-conditioned epidemiological models and a library of public health tools. EpiWorld predicts epidemic evolution and allows for rapid counterfactual policy testing, refining decisions based on simulated outcomes and accumulated lessons. Evaluations on COVID-19 and influenza data demonstrated that EpiWorld significantly reduces cumulative hospitalizations, outperforming existing reinforcement-learning and optimal-control baselines.
