This week U.S. health officials said they would begin screening travelers from West Africa for Ebola at five major U.S. airports. The first person diagnosed with Ebola in the U.S., Thomas Eric Duncan, died at a Dallas hospital. He had been infected in his home country of Liberia. A vigil was held in his honor at Wilshire Baptist Church in Dallas, where his fiancée is a member. In recent weeks, faith-based humanitarian groups such as Samaritan’s Purse and Catholic Relief Services have been ramping up aid to the African countries hit hardest by Ebola.
