DR Congo Ebola outbreak could become worst in history as thousands not being traced

Healthcare workers and officials warn that the surging Ebola outbreak in the Democratic Republic of Congo could become the worst in history due to tens of thousands of untraced contacts with ill patients. The head of Africa's Centre for Disease Control and Prevention highlighted this risk, comparing it to the 2014-2016 outbreak in Guinea, Liberia, and Sierra Leone that killed over 11,000 people.
