CDC – The Health Communicator’s Social Media Toolkit: “In the last several years, the use of Facebook, YouTube, Twitter, and other social media tools to disseminate health messages has grown significantly, and continues to trend upward. Using social media tools has become an effective way to expand reach, foster engagement, and increase access to credible, science‐based health messages. Social media and other emerging communication technologies can connect millions of voices to:

• Increase the timely dissemination and potential impact of health and safety information.
• Leverage audience networks to facilitate information sharing.
• Expand reach to include broader, more diverse audiences.
• Personalize and reinforce health messages that can be more easily tailored or targeted to particular audiences.
• Facilitate interactive communication, connection, and public engagement.
• Empower people to make safer and healthier decisions.”
