In the Democratic Republic of the Congo, Claude is helping teams respond to a rare and deadly strain of Ebola.

Judge as of 21 Oct 2026. True if credible evidence shows that, at or shortly before that date, organisations responding to an Ebola outbreak in the DRC (health ministry, WHO, NGOs, or partners) were using Claude in that response, and that the outbreak involved a rare or uncommon strain (for example a species other than Zaire ebolavirus, such as Bundibugyo or Sudan) that was deadly. Mostly true if Claude was used in the DRC Ebola response but the strain detail is slightly off (for example a common strain described as rare), or the use was by a single partner organisation. Mixed if Claude was used only in Ebola-related work outside the active field response (for example general research), or if there was no active outbreak at the time. Mostly false if Claude's use was only planned or piloted and not deployed. False if there is no Ebola outbreak response in the DRC involving Claude, as shown by responder or partner accounts that describe the tools used and leave Claude out.

Set before the research began.

   “Since May, teams on the ground in the Democratic Republic of Congo (DRC) have been fighting the Bundibugyo strain of the Ebola virus.”

   “To evaluate the answers and reports, Anthropic's Claude model was used. Among those involved in the study were CEPI, the WHO Regional Office for Africa and the national biomedical research institute INRB.”

   “As of 31 October 2026, a total of 10,467 confirmed cases and 5,103 deaths had been reported across 67 health zones in eight provinces, with the outbreak surpassing the 10,000-case mark.”

   “Since May, teams on the ground in the Democratic Republic of the Congo (DRC) have been combating a rare strain of Ebolavirus called Bundibugyo (BDBV).”

The evidence shows an active Bundibugyo Ebola outbreak in the DRC (E1, E3, E4) and that Claude was used to evaluate answers and reports in a study involving CEPI, the WHO Regional Office for Africa and INRB (E2). It does not show whether that use was part of the active field response or separate research, and the criteria treat those cases differently.
