The crisis shows how modern epidemics turn less on laboratories than on whether fractured, frightened communities trust the people sent to help them.
Ebola causes severe fever, vomiting, diarrhea, and in some cases internal and external bleeding.
Tedros toured Ituri province, the outbreak's epicenter, and warned reporters that the response still trails a disease moving through territory no government fully controls.
Health workers confirmed the country's 17th Ebola outbreak on May 15, and the WHO soon escalated it to a public health emergency of international concern, its highest level of alarm.
The Bundibugyo strain, one of the species of Ebola virus known to cause disease in humans, carries no licensed vaccine and no approved treatment, which throws responders back onto isolation, supportive care, and persuasion.
At least four health workers have died in conditions consistent with the virus, a warning of how fast it can race through clinics short on gloves, gowns, and isolation rooms.
Tedros suspects the pathogen circulated unnoticed since January, a long lead that let it spread before laboratories caught the first cases in mid-May.
Congo has now logged 344 confirmed cases and 60 deaths, figures Tedros cited on June 3 as the toll kept rising.
The virus has spread across the Kivu provinces and over the border into Uganda, every affected zone scarred by years of armed conflict.
Health officials still recall the last major Ebola epidemic in these eastern provinces, when attacks on response teams and deep public suspicion let the virus spread long after it should have ended.
The outbreak has already slipped beyond Africa, with an American aid worker who fell ill in Congo evacuated abroad for care.
Tedros also pressed wealthy governments to drop the blanket travel restrictions that several countries, including the United States, imposed on the region, arguing the bans choke supply lines without slowing the virus.
Those provinces anchor one of the world's largest displacement crises, where fighting between government forces and the M23 movement uprooted more than 5.35 million people in 2025.
Crowded camps, broken sanitation, and shuttered clinics let measles, cholera, and malaria flourish beside Ebola, turning every new wave of refugees into a fresh corridor for infection.
Even before this emergency, the WHO counted 7.5 million people across Congo who needed urgent care in 2026, inside a health system already drained by chronic underfunding.
Insecurity and flight have held contact tracing near 45 percent of known contacts, and mistrust deepens the danger, with some local leaders telling Tedros they doubt Ebola exists.
Public health scholars have argued for years that outbreaks like this turn on social trust as much as biology, an insight drawn from medical anthropology.
Research on West Africa's Ebola epidemic found that quarantines imposed without local trust drove families into hiding and fed the very rumors that carried the disease farther.
WHO strategy now rests on that lesson, holding that responders contain outbreaks only when communities help lead them, never when outsiders impose control from above.
For Congo, that means winning over villages worn down by war and broken promises, a slower job than raising treatment tents or shipping protective gear.
Even so, Tedros pointed to a handful of early survivors, six in Congo and two in Uganda, as evidence that prompt care can pull patients through without any vaccine.
Tedros flew back to Geneva, leaving a response built on the oldest instruments in epidemiology: fast testing, careful isolation, safe burials, and the patient work of earning a frightened population's trust.
