There has been an outbreak at Disney World causing a resort shut down. This new mysterious illness appears to be communicable and the mode of transmission appears to be through droplets (sneezing/coughing). In this activity you will analyze the transmission of an unknown infectious agent from person to person as well as use deductive reasoning to determine "patient zero," the initial patient in the population to develop the infection.
Contagion Activity
Epidemiologists have noticed that multiple Disney workers have come down with a mysterious infection that causes coughing, fever, and difficult breathing. They believe the illness is communicable and the mode of transmission appears to be through droplets (sneezing/coughing). They have collected the last couple week's work schedule to assess which workers came into contact with each other.

Devise a way to determine Patient Zero. Determine your Patient Zero options by showing your work below (include image if you drew your solution on paper)
Now that you have narrowed down your patient zero to one or a couple individuals, generate a list of 5 questions that you want to ask when you interview the workers. Your questions should be designed to help you identify who patient zero is, as well as learn more about how this new mysterious disease spreads.
Why do you think the CDC (Center of Disease Control) attempts to determine patient zero when there is a disease outbreak?
