Nancy Cox, who for many years was a worldwide chief in influenza analysis, has died. Cox headed the influenza group on the Facilities for Illness Management and Prevention for 22 years, shepherding it from a department of 14 individuals to a division of over 100. She was additionally director of the World Well being Group’s Collaborating Heart for the Surveillance, Epidemiology, and Management of Influenza on the CDC.
Cox died Thursday from glioblastoma, a most cancers of the mind. She was 77.
A virologist, Cox led the CDC’s efforts to reply to seasonal flu and put together for pandemic influenza. However she was at the least as well-known for her work fostering world efforts to reinforce monitoring for the evolution of seasonal flu viruses and spot rising viruses with pandemic potential.
“She was a crucial part of connecting international locations throughout the globe,” mentioned Daniel Jernigan, who served as deputy director of the flu division below Cox, taking up when she retired in 2014. “Due to her imaginative and prescient, we’re higher ready for pandemics and offering higher prevention of influenza sickness and dying.”
Cox and the group she led contributed considerably to the present surveillance system that underpins the annual updating of flu vaccines.
“She was central to the mixing of recent applied sciences into vaccine pressure choice and pandemic preparedness actions and was all the time the primary to remind everybody what was at stake, the well being of hundreds of thousands,” mentioned Richard Webby, head of the WHO Collaborating Centre for Research on the Ecology of Influenza in Animals and Birds at St. Jude Youngsters’s Analysis Hospital, in Memphis.
Scientists who labored for and collaborated with Cox had been fast to reward her dedication, her diplomacy, and her efforts to increase world flu surveillance.
“There are a number of actually nice scientists concerned in influenza. … However no one had the form of respect and breadth and reverence that Nancy had. And it was actually clear why,” mentioned Keiji Fukuda, who was chief of influenza epidemiology below Cox earlier than shifting to the WHO’s influenza program in 2005.
“A part of it’s that she simply knew a lot about influenza — the science, the historical past, the up to date milieu. A part of it was as a result of she was form of on the nexus of science and public well being. However I feel a number of it was simply due to how she was.”
Individuals who knew Cox describe a scientist who was deeply educated about influenza but additionally a robust and supportive chief. Arnold Monto, a veteran flu researcher and professor emeritus on the College of Michigan, mentioned it was essential to Cox to assist junior colleagues increase their abilities, “in order that they actually developed and flourished.”
She was a terrific boss, mentioned Fukuda, who’s now retired.
“She could possibly be goofy. She could possibly be humorous. She could possibly be girlish. And he or she could possibly be very stern when she was upset,” he mentioned. “However what you knew is that she was all the time attentive, and she or he was truthful, she didn’t micromanage, and she or he anticipated you to work laborious. And while you checked out her for instance, you simply had been working for anyone that you just wished to work laborious for.”
Born and raised in rural Iowa, Cox acquired a bachelor’s diploma in bacteriology from Iowa State College. She then attended the College of Cambridge, in the UK, on a Marshall fellowship, the place she acquired a doctorate in virology.
She joined the CDC in 1975, and was named head of the influenza department in 1992.
Curiosity in her discipline exploded within the late Nineteen Nineties and once more within the mid-aughts when the H5N1 chicken flu virus started infecting and killing mass numbers of poultry in China and different components of Southeast Asia — and infecting and killing some individuals as nicely. There was monumental concern the world was on the verge of what would have been the primary flu pandemic in additional than three a long time, with all indicators on the time pointing to the likelihood it is perhaps terribly extreme. Within the early days of detection of human H5N1 infections, roughly half of confirmed instances died.
Cox and others aggressively promoted the necessity for pandemic preparedness.
“She was the point of interest of influenza response, surveillance, and analysis on this nation,” mentioned Anthony Fauci, former head of the Nationwide Institute for Allergy and Infectious Illnesses on the Nationwide Institutes of Well being.
“She was very, very, very nicely revered by colleagues at NIH, together with me.”
In 2006, Cox was named Federal Worker of the 12 months by the Partnership for Public Service, a nongovernmental group that promotes excellence in authorities staff. The identical 12 months she made the Time Prime 100 listing in a category that included Oprah, Invoice and Melinda Gates, Hillary Clinton, after which President George W. Bush.
Even though H5N1 continues to this present day to wreak havoc on poultry operations and infect an astonishing array of mammals — together with the occasional particular person — it has not triggered a pandemic. In an article STAT printed in 2019, Cox warned towards complacency in direction of this virus.
“We don’t understand how the story’s going to finish,” she mentioned.
After the startling 2024 discovery that H5N1 was infecting dairy cows in the US, Cox marveled at the way it continues to rewrite influenza dogma. “It appears that evidently these viruses should have some form of ‘particular sauce’ that has allowed them to seek out methods to persistently unfold, evolve, and trigger what seem like more and more critical issues in each wildlife and domesticated animals,” she instructed STAT in an e-mail.
Influenza is a famously mercurial virus. Cox typically mentioned: “For those who’ve seen one flu season, you’ve seen one flu season.” Nonetheless, influenza scientists had been taken unexpectedly in 2009 when as an alternative of the scary chicken flu pandemic, the world was hit with a pandemic attributable to an H1N1 virus that had advanced in pigs. Although the virus was thought to have emerged in Mexico, the primary two confirmed instances had been youngsters in California who had no connections to pigs or to one another. The CDC was on the middle of determining what was occurring.
Richard Besser, CEO of the Robert Wooden Johnson Basis, was performing CDC director on the time. He recalled his many interactions with Cox that tense spring. “In briefings to the general public, she gave the nation confidence that we had been doing all that we may to guard the well being of individuals right here and around the globe. She modeled what it was to be a real public servant,” he mentioned.
As she and her group had been racing to hint the origins of the virus and the way far it had unfold, Cox suffered a private tragedy. Her home was struck by lightning and burned to the bottom. Happily nobody was harm.
She was reported to have been again at work the subsequent day in garments that smelled of smoke. “It was devastating,” she mentioned. “However I flipped a swap in my thoughts to focus on what we thought would possibly flip right into a pandemic.”
Throughout her time on the helm of the CDC’s flu operations, world sharing of influenza viruses was an ongoing problem — one which Cox tackled relentlessly. Kanta Subbarao, who labored below Cox as part head for molecular genetics for a time — and later headed to Australia to run a WHO flu collaborating middle there — mentioned Cox labored laborious to construct relationships with influenza scientists in numerous international locations, together with China, and to assist them improve their scientific capability.
“We had Chinese language scientists [training at CDC] and we had collaborations and co-authorships and so forth. So I feel she labored very laborious to attempt to convey them into the worldwide umbrella of influenza surveillance,” mentioned Subbarao, who’s now within the division of microbiology and immunology at Laval College in Quebec Metropolis.
Jernigan mentioned Cox’s diplomatic abilities served the world nicely. “She acknowledged that you just don’t compel sharing, you actually invite it,” he mentioned. “And also you try this by opening up and offering one thing and bringing one thing to the desk.”
Cox is survived by her husband, Evan, a daughter, a stepson, and 4 grandchildren.
