In Spreading Infectious Diseases you will use two simulations to study how disease spreads. First, you will use a computer simulation and then a hands-on simulation. After the second simulation you will play the role of epidemiologists and try to figure out who started the spread of the disease. Epidemiologists call this person patient zero. In the Vaccines lesson you will observe and analyze a computer simulation of how the COVID-19 virus spreads under different conditions with different percentages of people vaccinated. You will also discuss a diagram that models how different public health measures can work together to protect our communities from infectious diseases like COVID-19.
