Read the entire manual on public health emergency response. This manual describes a potential cohesive complete public health response to a public health disaster. Not all aspects will be used in all responses. Much like ICS it can be scaled as appropriate.
Also, you can read these ( Wisner chapter 4: Emergency response,
Landesman chapter 3: Structure and Organization of Health Management in Disaster Response)
Find one example of a public health emergency in the United States in the last 20 years and develop the PowerPoint slides about the incident: What happened, who responded, what public health measures were involved and how did the situation resolve itself? Use the topics presented in the manual to shape your presentation. We expect that you will be able to cite specific details and page numbers from this manual to support how the incident was mitigated.
