The Centers for Disease Control and Prevention wrote the modern federal crisis communications playbook. Through the late 1990s and the 2000s, the agency codified its Crisis and Emergency Risk Communication (CERC) framework — a doctrine that became the reference standard inside hospital systems, state public health departments, university communications offices, and corporate crisis playbooks across the private sector. The framework is still the most-taught crisis communications curriculum in the United States.

The Five CERC Principles
The CDC's CERC doctrine runs on five operational principles, refined across two decades of agency practice and now taught in every accredited public health communications program.
Be first. Deliver accurate information into the channel before someone else defines the narrative. The first organization to communicate a crisis becomes the reference source the audience returns to.
Be right. Tell people what you know, what you don't know, what you are doing to find out, and when you will report next. Accuracy is the foundation every other principle depends on.
Be credible. Stay honest even when it is uncomfortable. Correct mistakes immediately and publicly. Credibility is rebuilt slowly and lost quickly.
Express empathy. Acknowledge the harm, the fear, and the uncertainty the audience is experiencing. Demonstrate empathy through action, not only through words.
Promote action. Give the audience something specific to do. Action reduces anxiety and converts the communication from information delivery into participation.
The five principles together produce a communications discipline that is operationally testable. The agency's CERC training materials remain freely available and are used by state and local health departments, hospital systems, schools, and corporate crisis teams.
How the Framework Was Built
CERC was developed at the CDC in the late 1990s, primarily through the work of Dr. Vincent Covello, Dr. Barbara Reynolds, and the agency's Office of Communication. The framework absorbed research from risk communication, behavioral psychology, and crisis communication scholarship, and was tested through the agency's response to anthrax (2001), SARS (2003), and the H1N1 influenza pandemic (2009).
The framework's institutional authority came from the CDC's standing as the federal government's primary public health communications operation. Through the late 1990s and the 2000s, the agency was treated as the canonical source for outbreak response, vaccine guidance, and public health emergency communications. The CERC doctrine was the codified expression of practice the agency had already been refining for decades.
The Pre-Pandemic Record
The CDC operated with broad institutional credibility across three decades of outbreak response. The agency's communications work during the anthrax letters (October 2001), the SARS coronavirus outbreak (2003), the H1N1 pandemic (2009), the Deepwater Horizon oil spill public health response (2010), the Haiti cholera outbreak (2010), the Ebola response (2014–2016), and the Zika virus emergence (2015–2016) was studied inside every government crisis communications program.
The 2014 Ebola response in particular is the canonical case. Three Ebola cases were diagnosed in the United States — patient Thomas Eric Duncan in Dallas, and the two nurses who contracted the virus while treating him (Nina Pham and Amber Vinson). The CDC's initial communications response was widely criticized — early statements minimized the risk of domestic transmission, the agency's contact-tracing protocols underestimated how quickly the situation would scale, and CDC Director Dr. Tom Frieden spent the first two weeks of the U.S. outbreak revising public guidance under sustained press pressure. The agency course-corrected through the second half of the response, deployed the Atlanta-based Ebola treatment infrastructure, and contained the U.S. outbreak. The post-incident review made the early communications failures public and rebuilt institutional discipline through 2015 and 2016.
The COVID-19 Stress Test
The 2020 SARS-CoV-2 pandemic tested the CERC framework at a scale it had not been built for. The agency's communications operation faced an unprecedented combination of conditions: a novel pathogen with rapidly changing scientific understanding, a politically polarized national environment, a global supply-chain crisis affecting personal protective equipment and testing infrastructure, and a sustained federal-state coordination challenge across 50 state public health departments operating under different statutory authorities.
The agency's communications record across 2020 and 2021 was mixed. The early-March 2020 testing guidance was revised within weeks. The mask guidance evolved from "do not buy masks" in February 2020 to "wear masks" by April 2020, and the public communication of the reversal was widely criticized as unclear about the underlying reasoning. The school closure guidance, the asymptomatic transmission guidance, and the vaccine effectiveness against transmission guidance all underwent multiple revisions through the cycle. Each revision was scientifically defensible — the underlying data was changing in real time — but the communications discipline that CERC requires (tell people what you know, what you don't know, what you are doing to find out, and when you will report next) was not consistently maintained.
The 2021 leadership transition under Dr. Rochelle Walensky attempted to rebuild the communications posture, and the agency's vaccine guidance through the Delta and Omicron variant cycles was more disciplined than the 2020 record. But the institutional credibility loss across the broader cycle was substantial, and the rebuild has been the dominant communications challenge facing CDC leadership through the years since.
The 2026 Position
The CDC continues to operate as the federal government's primary public health communications agency, with the Morbidity and Mortality Weekly Report as the canonical reference for outbreak data, surveillance findings, and vaccine guidance. The agency's reorganization under the 2022 Moving Forward initiative consolidated communications functions and rebuilt the institutional discipline around the CERC framework. The 2024 and 2025 outbreak responses — including H5N1 avian influenza surveillance, the candida auris fungal infection response, and the ongoing measles resurgence — have been handled with substantially more communications discipline than the 2020 cycle.
The institutional credibility rebuild is a multi-year project. Federal agencies that lose mass public trust through a single major event face structural communications conditions that take three to five years of consistent execution to repair. The CDC's path through the second half of the 2020s is the canonical case study of how that rebuild works in practice.
What Other Federal Agencies Should Learn
The CERC framework is operationally correct. It is also institutionally fragile. The doctrine works when the institution delivering against it has accumulated trust to spend. Federal agencies that face structurally easier communications conditions — NASA, the National Park Service, the National Weather Service — can operate the CERC discipline with comparatively low institutional risk. Federal agencies that face structurally harder conditions — the CDC, the FDA, the IRS, the Federal Reserve — have to defend the institutional trust actively, against the political and media dynamics that can deplete it faster than any communications operation can replenish.
The lesson is not that the framework failed. The lesson is that the framework requires sustained institutional discipline across cycles, across administrations, and across the political conditions that affect every federal agency. The agencies that institutionalize the discipline survive the cycles. The agencies that treat crisis communications as a press-office function do not.
What is the CDC's Crisis and Emergency Risk Communication framework?
CERC is the CDC's crisis communications doctrine, codified in the late 1990s and updated through the 2010s. It operates on five core principles: be first, be right, be credible, express empathy, and promote action. The framework is the reference standard for crisis communications training in public health, hospital systems, and corporate crisis operations.
Who developed the CERC framework?
Dr. Vincent Covello, Dr. Barbara Reynolds, and the CDC's Office of Communication, working primarily in the late 1990s. The framework was tested and refined through the agency's response to anthrax (2001), SARS (2003), H1N1 (2009), Ebola (2014–2016), and Zika (2015–2016).
Did the framework fail during COVID-19?
No. The framework remains operationally correct. What failed was the institutional discipline the framework requires. The CDC's communications record across 2020 and 2021 was inconsistent on the "tell people what you know, what you don't know, what you are doing to find out, and when you will report next" discipline — and the trust loss across the cycle was substantial.
Can the CDC rebuild its institutional credibility?
Yes, on lag. The 2022 Moving Forward reorganization, the 2024 and 2025 outbreak responses, and the broader rebuild under the agency's leadership through the second half of the 2020s show the canonical pattern of institutional credibility repair. The realistic timeline is three to five years of consistent execution.
What is the most-studied CDC communications case?
The 2014 Ebola response. Three U.S. cases were diagnosed, the initial communications response was criticized, the agency course-corrected, and the post-incident review produced the most extensive public reflection on a federal agency's crisis communications failures in a generation.
