This toolkit was developed by the Electronic Media Branch, Division of News and Electronic Media, Office of the Associate Director of Communication at the Centers for Disease Control and Prevention (CDC). It was designed to provide guidance and to the share lessons learned in more than three years of integrating social media into CDC health communication campaigns, activities and emergency response efforts. In this guide, you will find information to help you get started using social media—from developing governance to determining which channels best meet your communication objectives to creating a social media strategy. You will also learn about popular channels you can incorporate into your plan, such as blogs, video-sharing sites, mobile applications and RSS feeds. This toolkit is intended for a beginner audience, although some viewers with an intermediate level may find parts of the toolkit useful.
