The Ebola outbreak in the Democratic Republic of the Congo has passed 2,000 confirmed deaths, a threshold that makes it, by the World Health Organization's accounting, the second-largest Ebola outbreak ever recorded and the fastest-growing on record. Al Jazeera, citing the WHO on August 11, put the toll at 2,011 confirmed deaths among 4,381 confirmed cases across five provinces [1]. That is a case fatality rate of roughly 46 percent: 2,011 of 4,381 is 45.9 percent [1].

The figure that carries the story is not the milestone but the slope beneath it. The WHO says at least 1,000 of the 2,011 deaths occurred in the last three weeks [1]. Close to half of everyone this outbreak has killed died in the most recent three-week window, which is what "fastest-growing on record" means in human terms rather than in rankings.

By total cases, the outbreak now trails only the 2014-16 West Africa epidemic, which killed 11,310 people [1]. That comparison sets both the scale and the gap in tools. The West Africa emergency ended with a proven Ebola vaccine, but it targets a different species of the virus. This outbreak is the Bundibugyo strain, for which, per Al Jazeera, "there is currently no approved treatment or vaccine" [1]. The WHO says vaccine trials are underway but would likely take months before results come in [1].

The outbreak also ran undetected for months before anyone declared it. Per Al Jazeera, the virus first emerged in February; the DRC and neighboring Uganda declared the outbreak on May 15 [1]. Three months separate the first cases from the declaration, a head start for a pathogen that kills close to half the people it infects. The response since has been slowed by strikes among unpaid health workers, by misinformation, and by burial practices that bring families into close contact with the highly infectious dead [1].

This desk last reported these numbers on August 10, when the freshest verifiable national count was six days old. Read against that record, the trajectory is steep: the WHO's July 30 bulletin counted 1,589 deaths among 3,605 cases, Al Jazeera's August 4 reporting counted 1,707 deaths among 3,802 cases, and the WHO figure carried on August 11 is 2,011 deaths among 4,381 cases [1]. Those are dated snapshots printed in sequence, not blended into a single running number. Earlier coverage of this outbreak carried diverging tallies from the health ministry, the European CDC, and the WHO; the August 11 WHO count supersedes that spread rather than averaging into it, and it is the figure this desk carries, attributed to the WHO as reported by Al Jazeera on August 11.

A milestone like 2,000 is a lagging indicator. It records deaths that had already happened by the time the count caught up, in an outbreak that hid for three months, has no vaccine for its strain, and killed at least 1,000 people in the three weeks before the threshold was crossed. The trials that might change that arithmetic are months from results, and the transmission chains they would be tested against are the same ones adding to the toll now. When the next dated WHO count lands, this desk will print it.
