  "Description": "A flexible framework for Agent-Based Models (ABM), the\n'epiworldR' package provides methods for prototyping disease\noutbreaks and transmission models using a 'C++' backend, making\nit very fast. It supports multiple epidemiological models,\nincluding the Susceptible-Infected-Susceptible (SIS),\nSusceptible-Infected-Removed (SIR),\nSusceptible-Exposed-Infected-Removed (SEIR), and others,\ninvolving arbitrary mitigation policies and multiple-disease\nmodels. Users can specify infectiousness/susceptibility rates\nas a function of agents' features, providing great complexity\nfor the model dynamics. Furthermore, 'epiworldR' is ideal for\nsimulation studies featuring large populations.",
