Dr. Craig Spencer “is a committed and responsible physician who always puts his patients first,” said a statement from New York Presbyterian/Columbia University Medical Center, where Spencer serves as an emergency room doctor. Before being diagnosed with Ebola, Spencer had been working with humanitarian aid group Doctor’s Without Borders fighting the virus’ outbreak in West Africa.

Spencer returned to the U.S. via New York’s John F. Kennedy International Airport on Oct. 17\. He began showing symptoms on Thursday, Oct. 23, when his temperature was [recorded](https://twitter.com/JohnJHarwood/status/525623361981140992) at a slightly elevated 100.3 degrees fahrenheit, New York Gov. Andrew Cuomo said Friday morning, clarifying widespread reports Thursday that Duncan’s temperature was above 103 degrees. Ebola can incubate undetected in the body for up to 21 days before an infected person shows symptoms. Ebola patients are not contagious until they show symptoms, and they become increasingly contagious as they get more sick. Spencer graduated from Baltimore’s Johns Hopkins University, studied Chinese language and literature at Henan University in China, earned a medical degree from Detroit’s Wayne State University School of Medicine and, in 2008, started his residency in New York, becoming a fellow at the Columbia University Medical Center’s International Medicine Program, according to information drawn from his LinkedIn profile by The Wall Street _Journal_. Spencer’s LinkedIn page has since been taken down. “He was an outstanding student, humanitarian, excellent physician,” one of Spencer’s professors told the _Journal_. “He’s done a lot of good international work. He had been to parts of the world—marginalized, disenfranchised—working to improve the human condition.” According to a friend who met Spencer through the website Couchsurfing, which connects travelers with free places to stay, he’s a runner who plays the banjo and speaks French, Chinese and Spanish.
