Community Health Simulation

A neighbourhood of a hundred residents, modelled as a classic Susceptible–Infected–Recovered outbreak around a central clinic. Adjust how contagious the disease is, how many people the clinic can treat at once, and how much the community invests in prevention, then watch the population shift from green (susceptible) through orange and red (treated vs. critical, depending on whether the hospital is overloaded) to blue (recovered) — a compact model of the epidemiology, resource allocation and prevention themes covered in the accompanying article.
