With a quick glance at Dr. Craig Spencer's work history, it is apparent he has an affinity for helping those in need. His work has taken him from hospital emergency rooms in New York to the rural clinics in Africa, where he has worked with limited resources to improve medical care. And now that work in Guinea, where he reportedly was helping treat Ebola patients, has put him at risk. Spencer, 33, tested positive for Ebola on Thursday, a law enforcement official briefed on the matter told CNN. The official spoke on condition of anonymity. While authorities have not publicly identified Spencer, they confirmed earlier Thursday that a Doctors Without Borders physician who recently returned to New York from West Africa exhibited symptoms of Ebola and was undergoing testing.Dr. Craig Spencer showed first symptoms on Thursday, an official saysSpencer, 33, was working in Guinea, helping treat Ebola patientsOn Facebook, Spencer asked people to support organizations fighting EbolaHe was taken to the hospital after developing a fever, the official says
