The whereabouts of nearly 300 people who tested positive for Ebola in the Democratic Republic of the Congo are unknown, Africa's top public health official warned on Thursday. Dr. Jean Kaseya, director general of the Africa Centers for Disease Control and Prevention (CDC), said the humanitarian crisis in conflict-affected areas has created a dire situation.

Health workers cannot reach more than 1 million people living in camps across the region, raising fears of undetected spread. Kaseya described the potential for "huge, huge community transmission" as the conflict blocks access to vulnerable populations. The warning signals a critical gap in outbreak response capabilities.

Modelling cited by the Africa CDC predicts thousands of Ebola cases and deaths by September if transmission is not contained. The 300 missing patients represent confirmed positive cases whose locations remain unknown, making contact tracing and isolation effectively impossible in those instances.

The convergence of armed conflict and epidemic response poses unique challenges. Displaced populations in inaccessible camps create conditions for rapid, silent spread. International health agencies face limited options without ceasefires or secure humanitarian corridors to reach affected communities.

Experts note that past Ebola outbreaks in the DRC have been contained through community engagement and rapid response, but the current security environment is unprecedented in its scale of disruption to health operations.
