Daniel B. Jernigan is an American physician, public health leader, and retired Captain with the United States Public Health Service. Jernigan is known for his work in infectious disease detection, outbreak readiness and response, and public health surveillance. He served thirty-one years at the U.S. Centers for Disease Control and Prevention (CDC) in leadership roles including director of the National Center for Emerging and Zoonotic Infectious Diseases (NCEZID), CDC deputy director for public health science and surveillance, and director of CDC's Influenza Division. He received the 2019 Samuel J. Heyman Service to America Medal (Science and Environment) for his public health service.

Education Jernigan earned a Bachelor of Science degree from Duke University, and later completed combined medical and public health training, receiving an MD from Baylor College of Medicine and an MPH from the University of Texas School of Public Health.

Career After completing EIS in CDC's Division of Bacterial and Mycotic Diseases, Jernigan worked as a CDC epidemiologist assigned to the Washington State Department of Health from 1996 to 1999 addressing emerging infections and antimicrobial-resistant infections.

Jernigan subsequently served as Epidemiology Section Chief for CDC's Division of Healthcare Quality Promotion. Media coverage and reports described investigations involving healthcare-associated, antimicrobial-resistant, and transplant-associated infections.

Beginning in 2006, Jernigan joined CDC's Influenza Division and from 2015 to 2021 served as director of the division, overseeing prevention and control of human, swine, and avian influenza infections in the U.S. and globally. Media reports from this period described his work during severe flu seasons and the 2009 influenza A(H1N1) pandemic. Jernigan led developments of surveillance and response innovations including the International Reagent Resource (IRR) for sharing test materials globally, and the Influenza Risk Assessment Tool which later was used for the WHO Tool for Influenza Pandemic Risk Assessment.

In 2021, Jernigan became CDC's deputy director for public health science and surveillance overseeing the agency's Data Modernization Initiative.

Publications Jernigan has authored over 160 peer-reviewed manuscripts and book chapters on bacterial, viral, and fungal diseases and on innovations for infectious diseases surveillance and public health informatics. This work led to changes in federal vessel sanitation requirements and inspections.

Bioterrorism-related anthrax Jernigan served as the lead for the CDC's Epidemiology Team in the Emergency Operations Center during the 2001 investigation into bioterrorism-related anthrax cases. Later reports describe how this effort informed and improved emergency responses subsequently facing CDC.

Severe acute respiratory syndrome (SARS) in Taiwan Jernigan led a team supporting the Taiwan Centers for Disease Control in 2003. Reports described the importance of adherence to infection control in stopping spread of SARS.

Infections from organ and tissue transplantation Jernigan supervised CDC teams investigating fatal transplant-associated infections due to rabies, West Nile virus (WNV), lymphocytic choriomeningitis virus (LCMV), and fatal Clostridium infections associated with cadaveric tissue allografts. Descriptions of investigations and subsequent changes to oversight and regulation have been reported.

During the response to the emerging influenza A(H1N1) pandemic virus, he led a task force responsible for outbreak response, epidemiology, surveillance, laboratory, international coordination, modelling, and other workstreams. Jernigan subsequently served as lead, Avian Influenza H7N9 Epidemiology and Laboratory Task Force, overseeing teams monitoring influenza A(H7N9) infections spreading in China in 2013.

Ebola, West Africa In 2014–2015, Jernigan served in leadership roles in CDC's Ebola response, including in Sierra Leone and as overall incident manager for CDC's global response.
