This application uses a compartmental epidemiological model, based on a classic SEIR model to describe the spread and clinical progression of COVID-19 in a population of individuals who have never been exposed to the disease previously.. The speed and extent to which the disease spreads - and how much it may ultimately overwhelm healthcare capacity - will depend on a number of rates related to disease transmission and progression. The application permits to set different clinical parameters, transmission rates, intervention parameters, healthcare capacity, and simulation values.
