Ebola in New York City

Dr. Craig Spencer, the physician now being treated for Ebola in New York City, is the kind of globe-trotting do-gooder who could walk into a small village in Africa and, even though he didn't know the language, win people over through hugs alone, according to people who worked with him.

Even before leaving for Guinea this summer to fight Ebola with Doctors Without Borders, the 33-year-old had amassed an ordinary man's lifetime worth of world travel, much of which was in the service of the poor
