The claim is true because multiple reports citing Congolese government and public-health data state that the Ebola outbreak in the Democratic Republic of the Congo had surpassed 5,000 cases, with one report giving a total of 5,021.
The Ebola outbreak in Congo has reached 5,000 reported cases.

Congo’s Ebola outbreak reaches 5,000 cases as it outpaces response efforts at unprecedented speed - The Washington Post

Key Evidence
The Washington Post reported on August 19 that government data showed the outbreak had reached 5,000 cases.
SANA and WKYU-FM provided the more precise figure of 5,021 confirmed cases, while Reuters reporting carried by WHBL said the total had exceeded 5,000.
These sources independently support the claim's central numerical assertion.
What the Evidence Shows
The claim accurately describes the situation reported on August 18-19, 2026. The Washington Post, NPR affiliate KVNF, Bay News 9, WKYU-FM, The Hindu, and other outlets reported that the outbreak had reached or exceeded 5,000 cases.
The most specific figure in the provided sources comes from SANA, which reported 5,021 cumulative confirmed cases. WKYU-FM similarly cited government data showing 5,021 cases, including 2,378 deaths. Reuters reporting reproduced by WHBL also stated that confirmed cases had exceeded 5,000.
The wording "reported cases" is broadly supported, although the available reports more specifically describe the figure as cumulative confirmed cases or cases recorded in government data. The evidence therefore supports the central claim without a material factual error.
The sources also describe the outbreak as spreading rapidly and creating major response challenges. Those broader characterizations are not necessary to establish the numerical claim, and the provided excerpts do not independently document all details about the outbreak's speed or global-health status.
