>> A health worker is sprayed with chlorine outside the Bikoro Hospital Isolation Ward. A new Ebola case had just arrived, bringing the number of suspected cases in the Democratic Republic of Congo to more than 35, many of whom have died. Local health officials are worried. In 2014, when Ebola last emerged in Africa, it killed 11,300 people, in Guinea, Sierra Leone, and Liberia.
Back then, the World Health Organization was widely criticized for being too slow to respond, but this time they say they're ready. They've sent medical teams to the region and plan to deploy an experimental vaccine they hope will contain the virus. If left untended, Ebola can spread quickly, mainly through the transmission of bodily fluids.
Symptoms include headaches, muscle pain, diarrhea and eventually uncontrollable bleeding, which can lead to death. Ebola has no cure but with a rapid response, health officials say it can be controlled.
