KINSHASA, Democratic Republic of the Congo — A new Ebola case has been confirmed in the Democratic Republic of Congo, health authorities said Saturday, declaring an outbreak nearly four months after the last one ended in the central African nation. The case was confirmed in a 31-year-old man who began experiencing symptoms on April 5 in the city of Mbandaka, the World Health Organization said. He reportedly sought treatment at a health facility after more than a week of being taken care of at home.
