A woman and her child were the first two cases confirmed with Ebola in Congo’s South Kivu region this week, opening a new front in the fight against the outbreak.
Health officials said on Friday that the latest cases were more than 700 km (430 miles) south of where the outbreak was first detected.
Ebola has killed at least 1,900 people in Democratic Republic of Congo over the past year. This is the second biggest toll ever and militia violence combined with local resistance have made the outbreak harder to contain.
The 24-year-old woman had been identified as a high-risk contact of another Ebola case in Beni, more than 700 km north, last month, according to a government statement issued on Friday.
She travelled by bus, boat and road with her two children to Mwenga, in South Kivu, where she died on Tuesday night, according to a slide from a presentation by health officials.
