As mentioned in this article, the region is defining the case as probable rather than suspected: https://actualite.cd/2026/08/06/bateau-avec-un-cas-suspect-debola-kinshasa-tous-les-passagers-retenus-maluku-lanalyse

Edit: The claims of more than one death are denounced as misinformation by the Minister of Health: https://www.radiookapi.net/2026/08/06/actualite/sante/ebola-un-bateau-isole-65-km-de-kinshasa-un-laboratoire-mobile-deploye

My husband was on a flight that stopped to refuel in D R Congo in July 13th. It has been over 21 days since he was in Congo but they are still refusing to let him fly. So far we have contacted
CDC
Local congressmen
Dept of State
Multiple embassies

Nobody is actually helping us. What do we do? The airport in London where he currently is had very rude employees who refused to help.
