Africa’s top public health officials are warning that the Ebola outbreak in the Democratic Republic of Congo could become the worst ever recorded if transmission does not slow. Reporting from multiple outlets cites Africa CDC director Jean Kaseya, who says the scale of untraced exposure is a major concern. The warnings highlight that tens of thousands of people who had contact with individuals who are ill with Ebola have not yet been traced and tested, limiting health teams’ ability to quickly identify new cases and stop further spread.

The coverage also references analysis by an infectious disease epidemiologist discussing the current containment efforts and the risk of the outbreak worsening. While the reports differ in wording and emphasis, they converge on the same central message: ongoing outbreak control depends on improving contact tracing and preventing continued transmission. All sources describe the warning as conditional, tied to whether response measures are able to flatten transmission rates in the coming period.
