A UN medical worker who contracted Ebola while working in Liberia died late Monday night in a hospital in Leipzig, Germany. The man, whose identity has not yet been released, died despite receiving “intensive medical procedures,” the St. George Hospital said. His case prompted the UN’s Liberian peacekeeping mission to place 41 workers under “medical observation.” The man was flown to Germany for treatment on Oct. 9, the third Ebola patient to be flown to the country for care. The announcement comes after the CDC identified the second U.S. case of Ebola as Dallas nurse Nina Pham. She contracted the virus when caring for Thomas Eric Duncan, who passed away last week. Pham is one of 70 people who cared for him. Since her diagnosis, many are questioning whether Ebola safety procedures adequately protect medical workers.
