WASHINGTON, DC—In an early Tuesday morning talk at the American Society for Microbiology’s Biothreats conference, Dr. Anthony Fauci revealed what he said in his first meeting with the Trump Administration. Of course, he couldn’t resist dropping decades of knowledge about disease outbreaks at the same time.

Like all incoming administrations, the Trump Administration called on Dr. Fauci for a briefing on what to expect and how it should prepare for inevitable outbreaks during its time in office. Fauci is uniquely qualified to fill this role.

Dr. Fauci is not only an infectious disease expert and researcher; he’s been the director of the National Institute of Health’s National Institute of Allergy and Infectious Diseases since 1984. He’s helped oversee US research on and responses to everything from the emergence of HIV/AIDS, to bird flu, SARS, chikungunya, drug-resistant microbes, and Zika. When American healthcare workers came down with Ebola in 2014 and 2015, he was personally involved in their treatment at the NIH—he suited up and attended their bedsides.
