Communicating during emergencies can be difficult, and large-scale emergencies can pose more expansive challenges when it comes to communicating public information. This session teaches participants how to harness social media tools for a mass antibiotic dispensing campaign where the public will need to go to a point of dispensing site to receive life-saving medicine. In addition, participants will learn the advantages of social media tools and how to develop a message strategy for using these tools. Social media efforts on public health topics are used to illustrate best practices.
