Patient Zero is an interactive simulation that aims to explain SIR modeling and R0 through a playable disease outbreak scenario. Epidemiologists use these models to predict how a virus spreads through a population of people. In the simulation, players can take actions such as implementing disease control measures like vaccinations and quarantine to flatten the curve and slow the spread of the disease. The goal of the simulation is to help players understand the importance of public health measures in controlling the spread of infectious diseases.
