Responders in DRC hunt Ebola door to door as cases surpass 4,000

With more than 4,000 cases reported in Democratic Republic of Congo, the Africa Centers for Disease Control and Prevention say responders need to shift focus to door-to-door disease tracking. The World's Host Marco Werman learned more from Dr. Mesfin Teklu Tessema, head of the health unit at the International Rescue Committee. He also spoke with Trish Newport, emergency program manager for Doctors Without Borders. She's based in the city of Bunia, on the frontlines of the fight to contain Ebola.
