Lesson 5: Infectious Disease and Human Density


In this activity, you are playing the role of a Public Health Investigator (PHI) assigned to a case. In your city, there has been a recent outbreak of sickness that is affecting dozens of people. The doctors report that the illness is caused by a bacterial infection. All of these people have reported a similar illness over the past 24 hours. They have reported nausea, diarrhea, fever and chills. However, the infection is generally not transferable from person-to-person. Therefore, people who are sickened by the bacteria must be acquiring the infection from a source.
