Ebola outbreak becomes third largest, spreading rapidly
▼ Summary
– The Ebola outbreak in Ituri province, DRC, has nearly 750 cases, 177 deaths, and around 1,400 contacts being traced, making it the third largest on record.
– WHO raised the national risk level from “high” to “very high,” while regional risk remains “high” and global risk “low.”
– A delayed detection and response allowed the outbreak to balloon, with the earliest suspected case on April 24 but WHO not alerted until May 5.
– The outbreak involves the rare Bundibugyo virus, which has no established vaccines or therapeutics, leaving case finding, isolation, and contact tracing as main tools.
– Response efforts face challenges including armed conflict, population mobility, weak health systems, and acute hunger in affected areas.
The Ebola outbreak in the Democratic Republic of the Congo’s Ituri province is accelerating at an alarming rate. According to a World Health Organization press briefing on Friday, confirmed and suspected cases are approaching 750, with 177 deaths reported and roughly 1,400 contacts under active surveillance. These figures already mark this as the third largest Ebola outbreak on record, despite being officially recognized only a week ago, on May 15. WHO Director-General Tedros Adhanom Ghebreyesus described the virus as “spreading rapidly.”
In response, the WHO has raised its internal risk assessment from “high” to “very high” at the national level. Regional risk remains “high,” while the global threat is still considered “low,” Tedros noted.
Officials have acknowledged that a delayed detection and response allowed the outbreak to grow significantly before containment efforts could begin. Dr. Anne Ancia, a WHO representative speaking from the DRC during the briefing, explained that when teams arrived, they found the virus had “already rampant and silently disseminating for a few weeks already.” The earliest suspected case, identified during the investigation, was a health worker who developed symptoms on April 24 in Bunia, Ituri’s capital. The WHO was not alerted to a potential outbreak until May 5, when reports emerged of a cluster of unexplained, fatal infections that had killed four health workers. By the time a WHO team reached the area, 80 cases had already been recorded.
“Now we are sprinting behind [the virus] so that we can really try to control this outbreak, and because it is still transmitting for the time being, yes, the number [of cases] will keep rising for some time until we are really able to put all the response operation in place,” Ancia said.
Compounding the challenge, this outbreak involves the Bundibugyo virus, a rarer strain for which no approved vaccines or treatments exist. Without those tools, containment relies on active case finding, isolation, and contact tracing. The response is further complicated by the region’s volatile conditions: armed conflict, high population mobility, fragile health systems, and millions of people facing acute hunger and in need of humanitarian aid.
