Do a lot of people in your neighborhood all seem to have the same sickness? Are people concerned about high rates of cancer? Your community may want to explore the possibility of a disease cluster, which happens when there is a higher number of cases of disease than expected. When communities hear about cases of disease in their neighborhood, they are rightfully concerned. However, the results of investigations by the health department often find no evidence of a cluster. This course will help you understand what a disease cluster is and how it is studied. The goal is to empower community (or citizen) scientists, and to help build better relationships between communities and health officials.
