Sierra Leone Declares Emergency Amid Ebola

The president of Sierra Leone declared a public health emergency as the Ebola crisis blamed for nearly 700 deaths deepened across West Africa, vowing to quarantine sick patients at home and conduct house-to-house searches for others who may have been exposed. The announcement from President Ernest Bai Koroma late Wednesday came as neighboring Liberia also ramped up its efforts to slow the virulent disease's spread, shutting down schools and ordering most public servants to stay home from work. The U.S. Peace Corps also was evacuating hundreds of its volunteers in the affected countries. Two Peace Corps workers are under isolation outside the U.S. after having contact with a person who later died of the Ebola virus, a State Department official said.
