This episode is brought to you by Wondery in partnership with National Geographic in anticipation of their new series, The Hot Zone. In 2014, Ebola is tearing through Guinea, Liberia and Sierra Leone, but the deadly disease hasn’t yet made landfall in the United States. Then Thomas Eric Duncan, a Liberian visiting his fiancee and son in Dallas, stumbles into a local hospital with a fever. His eventual diagnosis — Ebola — sets off a nationwide panic that a full-scale outbreak might be looming. As local healthcare workers and epidemiologists put their lives on the line confronting a crisis they were never trained for, government officials struggle to mount an effective response.
