Visit the Public Health department and look at the disease data.
Look at the Infectious Diseases, Preventable Diseases, and Sexually Transmitted Diseases. Pick one reportable disease.
Research the details of the disease using the CDC website and other sources.
In a short document designed to explain the PSA to your faculty: 
Clearly describe the disease
Explain the chain of transmission
Discuss strategies a nurse would use to decrease the spread of this disease
Include the CDC mandatory reporting requirements for the disease
Using a recording tool, develop a 15-second (45-60 words) radio PSA that could be used in Sentinel City® to alert the residents about the infectious disease. Make sure the PSA is in layperson terms and include how to find out more about the disease.
