spurred the creation of the Epidemic Intelligence Service (EIS) as a two-year postgraduate training program in epidemiology. The success of the EIS program led to the launch of Field Epidemiology Training Programs (FETP) in 1980, training more than 18,000 disease detectives in over 80 countries. In 2020, FETP celebrated the 40th anniversary of the CDC's support for Thailand's Field Epidemiology Training Program. Thailand was the first FETP site created outside of North America and is found in numerous countries, reflecting CDC's influence in promoting this model internationally. The Training Programs in Epidemiology and Public Health Interventions Network ( TEPHINET) has graduated 950 students. The mission of the CDC expanded beyond its original focus on malaria to include

Shortly thereafter, Tuberculosis Control was transferred (in 1960) to the CDC from PHS, and then in 1963 the Immunization program was established. It became the National Communicable Disease Center effective July 1, 1967, and the Center for Disease Control on June 24, 1970. At the end of the Public Health Service reorganizations of 1966–1973, it was promoted to being a principal operating agency of PHS.


Recent history

It was renamed to the plural Centers for Disease Control effective October 14, 1980, as the modern organization of having multiple constituent centers was established. By 1990, it had four centers formed in the 1980s: the Center for Infectious Diseases, Center for Chronic Disease Prevention and Health Promotion, the Center for Environmental Health and Injury Control, and the Center for Prevention Services; as well as two centers that had been absorbed by CDC from outside: the

In her statement to all CDC employees, she said: "For 75 years, CDC and public health have been preparing for COVID-19, and in our big moment, our performance did not reliably meet expectations." Based on the findings of an internal report, Walensky concluded that "The CDC must refocus itself on public health needs, respond much faster to emergencies and outbreaks of disease, and provide information in a way that ordinary people and state and local health authorities can understand and put to use" (as summarized by the New York Times).

The cuts also terminated 16 of the 24 Laboratory Leadership Service program fellows, a program designed for early-career lab scientists to address laboratory testing shortcomings of the CDC. In the following month, the Trump administration quietly withdrew its CDC director nominee, Dave Weldon, just minutes before his scheduled Senate confirmation hearing on March 13. In April 2025, it was reported that among the reductions is the elimination of the Freedom of Information Act team, the Division of Violence Prevention, laboratories involved in testing for antibiotic resistance, and the team responsible for determining recalls of hazardous infant products. Additional cuts affect the technology branch of the Center for Forecasting and Outbreak Analytics, which includes software engineers and computer scientists supporting the centre established during the COVID-19 pandemic to improve disease outbreak prediction.


Organization

The CDC is organized into centers, institutes, and offices (CIOs), with each organizational unit implementing the agency's activities in a particular area of expertise while also providing intra-agency support and resource-sharing for cross-cutting issues and specific health threats. As of the most recent reorganization in February 2023, the CIOs are: *

The change to requiring Senate confirmation was due to a provision in the Consolidated Appropriations Act, 2023. Twenty directors have served the CDC or its predecessor agencies, including three who have served during the Trump administration (including Anne Schuchat who twice served as acting director) and three who have served during the Carter administration (including one acting director not shown here). Two served under Bill Clinton, but only one under the Nixon to Ford terms.

Areas of focus


Communicable diseases

The CDC's programs address more than 400 diseases, health threats, and conditions that are major causes of death, disease, and disability. The CDC's website has information on various infectious (and noninfectious) diseases, including

Division of Select Agents and Toxins

Within the division are two programs: the Federal Select Agent Program (FSAP) and the Import Permit Program. The FSAP is run jointly with an office within the U.S. Department of Agriculture, regulating agents that can cause disease in humans, animals, and plants. The Import Permit Program regulates the importation of "infectious biological materials." The CDC runs a program that protects the public from rare and dangerous substances such as
anthrax Anthrax is an infection caused by the bacterium '' Bacillus anthracis'' or ''Bacillus cereus'' biovar ''anthracis''. Infection typically occurs by contact with the skin, inhalation, or intestinal absorption. Symptom onset occurs between one ...

. The program, called the Federal Select Agent Program, calls for inspections of labs in the U.S. that work with dangerous pathogens. During the 2014 Ebola outbreak in West Africa, the CDC helped coordinate the return of two infected American aid workers for treatment at Emory University Hospital, the home of a special unit to handle highly infectious diseases. As a response to the 2014 Ebola outbreak, Congress passed a Continuing Appropriations Resolution allocating $30,000,000 towards CDC's efforts to fight the virus.


Non-communicable diseases

The CDC also works on non-communicable diseases, including chronic diseases caused by
obesity Obesity is a medical condition, considered by multiple organizations to be a disease, in which excess Adipose tissue, body fat has accumulated to such an extent that it can potentially have negative effects on health. People are classifi ...
, physical inactivity and tobacco-use. The work of the Division for Cancer Prevention and Control, led from 2010 by Lisa C. Richardson, is also within this remit.


Antibiotic resistance

The CDC implemented their ''National Action Plan for Combating Antibiotic Resistant Bacteria'' as a measure against the spread of
antibiotic resistance Antimicrobial resistance (AMR or AR) occurs when microbes evolve mechanisms that protect them from antimicrobials, which are drugs used to treat infections. This resistance affects all classes of microbes, including bacteria (antibiotic resis ...
in the United States. This initiative has a budget of $161million and includes the development of the Antibiotic Resistance Lab Network.


Global health

Globally, the CDC works with other organizations to address global health challenges and contain disease threats at their source. They work with many international organizations such as the
World Health Organization The World Health Organization (WHO) is a list of specialized agencies of the United Nations, specialized agency of the United Nations which coordinates responses to international public health issues and emergencies. It is headquartered in Gen ...
(WHO) as well as ministries of health and other groups on the front lines of outbreaks. The agency maintains staff in more than 60 countries, including some from the U.S. but more from the countries in which they operate. The agency's global divisions include the Division of Global HIV and TB (DGHT), the Division of Parasitic Diseases and Malaria (DPDM), the Division of Global Health Protection (DGHP), and the Global Immunization Division (GID). The CDC has been working with the WHO to implement the ''International Health Regulations'' (IHR), an agreement between 196 countries to prevent, control, and report on the international spread of disease, through initiatives including the Global Disease Detection Program (GDD). The CDC has also been involved in implementing the U.S. global health initiatives

Travelers' health

The CDC collects and publishes health information for travelers in a comprehensive book, ''CDC Health Information for International Travel'', which is commonly known as the "yellow book." The book is available online and in print as a new edition every other year and includes current travel health guidelines, vaccine recommendations, and information on specific travel destinations. The CDC also issues travel health notices on its website, consisting of three levels: * "Watch": Level 1 (practice usual precautions) * "Alert": Level 2 (practice enhanced precautions) * "Warning": Level 3 (avoid nonessential travel)


Vaccine safety

The CDC uses a number of tools to monitor the safety of vaccines. The Vaccine Adverse Event Reporting System (VAERS), a national vaccine safety surveillance program run by CDC and the FDA. "VAERS detects possible safety issues with U.S. vaccines by collecting information about adverse events (possible side effects or health problems) after vaccination." The CDC's Safety Information by Vaccine page provides a list of the latest safety information, side effects, and answers to common questions about CDC recommended vaccines. The

(VSD) works with a network of healthcare organizations to share data on vaccine safety and adverse events. The Clinical Immunization Safety Assessment (CISA) project is a network of vaccine experts and health centers that research and assist the CDC in the area of vaccine safety. CDC also runs a program called V-safe, a smartphone web application that allows COVID-19 vaccine recipients to be surveyed in detail about their health in response to getting the shot.

Controversy over the Morbidity and Mortality Weekly Report

During the pandemic, the CDC

(HHS) to modify its reporting so as not to conflict with what Trump was saying about the pandemic. Starting in June 2020, Michael Caputo, the HHS assistant secretary for public affairs, and his chief advisor Paul Alexander tried to delay, suppress, change, and retroactively edit MMR releases about the effectiveness of potential treatments for COVID-19, the transmissibility of the virus, and other issues where the president had taken a public stance. Alexander tried unsuccessfully to get personal approval of all issues of MMWR before they went out. Caputo claimed this oversight was necessary because MMWR reports were being tainted by "political content"; he demanded to know the political leanings of the scientists who reported that

had little benefit as a treatment while Trump was saying the opposite. In emails Alexander accused CDC scientists of attempting to "hurt the president" and writing "hit pieces on the administration". In October 2020, emails obtained by ''Politico'' showed that Alexander requested multiple alterations in a report. The published alterations included a title being changed from "Children, Adolescents, and Young Adults" to "Persons." One current and two former CDC officials who reviewed the email exchanges said they were troubled by the "intervention to alter scientific reports viewed as untouchable prior to the Trump administration" that "appeared to minimize the risks of the coronavirus to children by making the report's focus on children less clear."


Eroding trust in the CDC as a result of COVID-19 controversies

A poll conducted in September 2020 found that nearly 8 in 10 Americans trusted the CDC, a decrease from 87 percent in April 2020. Another poll showed an even larger drop in trust with the results dropping 16 percentage points. By January 2022, according to an

poll, only 44% of Americans trusted the CDC compared to 69% at the beginning of the pandemic. As the trustworthiness eroded, so too did the information it disseminates. The diminishing level of trust in the CDC and the information releases also incited "

" with the result that "just 53 percent of Americans said they would be somewhat or extremely likely to get a vaccine." In September 2020, amid the accusations and the faltering image of the CDC, the agency's leadership was called into question. Former acting director at the CDC, Richard Besser, said of Redfield that "I find it concerning that the CDC director has not been outspoken when there have been instances of clear political interference in the interpretation of science." In addition, Mark Rosenberg, the first director of CDC's National Center for Injury Prevention and Control, also questioned Redfield's leadership and his lack of defense of the science. Historically, the CDC has not been a political agency; however, the
COVID-19 pandemic The COVID-19 pandemic (also known as the coronavirus pandemic and COVID pandemic), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), began with an disease outbreak, outbreak of COVID-19 in Wuhan, China, in December ...
, and specifically the Trump administration's handling of the pandemic, resulted in a "dangerous shift" according to a previous CDC director and others. Four previous directors claim that the agency's voice was "muted for political reasons." Politicization of the agency has continued into the Biden administration as COVID-19 guidance is contradicted by State guidance and the agency is criticized as "CDC's credibility is eroding". In 2021, the CDC, then under the leadership of the Biden administration, received criticism for its mixed messaging surrounding COVID-19 vaccines, mask-wearing guidance, and the state of the pandemic.


Gender censorship

On February 1, 2025, the CDC ordered its scientists to retract any not yet published research they had produced which included any of the following banned terms: "Gender, transgender, pregnant person, pregnant people, LGBT, transsexual, non-binary, nonbinary, assigned male at birth, assigned female at birth, biologically male, biologically female”. Larry Gostin, director of the World Health Organization Center on Global Health Law, said that the directive amounted to censorship of not only government employees, but private citizens as well. For example, if the lead author of a submitted paper works for the CDC and withdraws their name from the submission, that kills the submission even if coauthors who are private scientists remain on it. Other censored topics include DEI,

On February 4, Doctors for America filed a federal lawsuit against the CDC, Food and Drug Administration, and Department of Health and Human Services, asking the removed websites to be put back online. On February 11, a judge ordered removed pages to be restored temporarily while the suit is being considered, citing doctors who said the removed materials were "vital for real-time clinical decision-making".
