South Sudan continues to face significant challenges related to Ebola preparedness, particularly given the continuous and largely undocumented high-volume cross-border movements with Uganda and the Democratic Republic of Congo, both of which have experienced Ebola outbreaks. Meanwhile, Jonglei state has seen a drastic exacerbation of conflict dynamics since late 2025, leading to multiple displacement cycles.

The high volume of undocumented cross-border movement poses a significant risk for the spread of Ebola. Ongoing conflict in Jonglei state creates access constraints and leaves populations underserved and hard-to-reach for humanitarian assistance.

Conflict in Jonglei state has triggered multiple cycles of displacement, contributing to the over half a million internally displaced persons in the country. The continuous cross-border movement also creates potential health risks for communities.

The specific impact of the recent conflict exacerbation on humanitarian needs and access in Jonglei state is not yet detailed.
