Congo’s Ebola deaths pass 5,000, with no vaccine for this strain and 80% of new cases untraced
It is already the second-deadliest Ebola outbreak on record and has reached Uganda, Kenya and Nigeria.
Congo’s Health Ministry reported 5,026 deaths among 10,351 people infected in the Ebola outbreak declared in mid-May, a fatality rate near 50%. The outbreak is caused by the Bundibugyo virus, for which there is no approved vaccine or treatment. Cases have also been confirmed in Uganda, Kenya and Nigeria, making it the most geographically widespread Ebola outbreak in Africa.
5,026 deaths among 10,351 infections; 2,788 people have recovered.
Reported · Congo Health Ministry data, via APAn effective vaccine and antibody treatments exist only for the Zaire type of Ebola, not for Bundibugyo; for other types, research continues and care is supportive.
Confirmed · WHO fact sheetAbout 80% of new cases come from outside the chain of monitored contacts.
Reported · Africa CDC, via APHealth workers at treatment centers in Ituri and North Kivu have struck over months of unpaid wages.

None. Responders note early treatment improves survival, so faster testing is the main lever available.
Communities in Ituri and North Kivu, where armed conflict limits health workers’ reach, and unpaid frontline staff.
The number is not the whole story.
The fatality rate here is reported deaths divided by reported infections. Because some deaths happen before testing, both numbers likely undercount the true toll.
5,026 deaths among 10,351 infections is a rate of about 49%. That is less than half the toll of the 2014–2016 West Africa epidemic, but this outbreak is only five and a half months old.
A near-50% fatality rate with no vaccine means every untraced case matters. The 80% untraced share is the number to watch, more than the death count itself.

What came before?
The outbreak was declared in mid-May and caught authorities by surprise. The only larger Ebola outbreak was in West Africa from 2014 to 2016, which killed about 11,000 people across several countries over two years.
What is reported?
The virus has spread to 67 of Congo’s 178 health zones in eight of 26 provinces; Ituri and North Kivu account for 4,792 of the deaths. Kenya has confirmed eight cases and two deaths, and Nigeria one case, evacuated to Switzerland.
What remains open?
Watch the share of new cases arising among known contacts, the main sign that tracing is catching up, and whether health-worker pay disputes are resolved.

Why it matters
Containment depends on tracing every contact of every patient. Africa CDC says about 80% of new cases come from outside monitored contacts, and the WHO says a third of deaths occur before patients are tested, which lets the virus spread unseen.
What remains unresolved
Can contact tracing recover when four in five new cases come from unknown chains of transmission?
