Communication During the Pandemic

Be First - Be Right - Be Credible

  • The agency’s mission to protect public health was supported by communications founded on emergency risk communications principles of quickly, proactively and transparently communicating accurate information about the situation
  • This included clearly stating CDC’s goals and actions in response to the evolving situation and acknowledging what was not known as well as what was known. The goal was to inform the public, but to avoid causing unnecessary fear
  • From the earliest days of the pandemic, CDC clearly and repeatedly stated its goals to “reduce transmission and illness severity, and to provide information to help health care providers, public health officials and the public address the challenges posed by the new virus.” Communications messages were tempered by the values – Be first, be right, and be credible

  • CDC quickly disseminated information to support those stated goals and dozens of communications tools were used to reach out to audiences across the spectrum, from the public to pharmacists to diagnostics experts to international partners and countries around the globe
  • During the early days of the outbreak especially, the release and exchange of information was conducted on a 24-hour cycle and included frequent updates to media and the public, as well as the consistent use of a body of core spokespersons, daily information outreach to partners, and rapid establishment and daily maintenance of extensive Web content related to the emergency response
