The Ebola outbreak in the Democratic Republic of the Congo (DRC) isn't contained yet, now infecting people across 61 health zones spread over six provinces. The World Health Organisation (WHO) confirmed this grim expansion this week, with cases reaching Kayna Health Zone in North Kivu. The provinces battling this outbreak are Bas-Uélé, Haut-Uélé, Ituri, North Kivu, South Kivu, and Tshopo.
Transmission patterns remain a puzzle, the WHO reports. Despite ongoing efforts to fight the virus, it keeps spreading geographically and even increasing in some areas. This is worrying because it means the virus is finding new places to take hold and continuing its deadly work in others.
A significant challenge for health workers is the delay in detecting new cases. When cases aren't caught early, the virus has more chances to spread within families, across communities, and even within health facilities. This makes stopping it much harder, and it also means people might not get the treatment they need fast enough.
Access to prompt medical care is also a hurdle. The challenges in cutting off transmission routes mean response teams are facing an uphill battle. To stand a chance, the WHO stresses the need for better surveillance – keeping a close eye on potential spread – and quick, decisive action when cases are found, along with early treatment.
As of September 7th, the DRC has sadly recorded 6,757 confirmed cases of Ebola caused by the rare Bundibugyo virus. Out of these, a staggering 3,267 people have died. That's a crude case fatality ratio of 48.3 per cent, meaning almost half of those who contract the virus don't survive.
This latest update comes less than a month after the WHO labelled this outbreak as the second-largest Ebola outbreak ever recorded. Back then, the numbers were lower: 4,449 confirmed cases across 53 health zones in five provinces. But even then, the signs were worrying.
The WHO had already warned that this outbreak was moving faster than previous ones at the same stage. It was on a trajectory that could potentially rival the 2014–2016 West African outbreak, which remains the biggest in history. The fact that it's the Bundibugyo species, which doesn't have a specific vaccine like the more common Zaire species, adds another layer of difficulty.
Cases are being found in concerning ways. In August, the WHO noted that many cases were being identified in communities rather than in treatment centres. Many were also outside of known contact lists. This suggests that some transmission chains are still hidden, slipping through the fingers of contact tracers.
Response measures are in full swing. These include trying to trace everyone who might have come into contact with infected individuals, setting up treatment centres, deploying safe burial teams, running laboratories, and engaging with communities. Yet, the continued spread shows just how critical it is to beef up surveillance and ensure people are detected and treated early, especially in communities and healthcare facilities where the risk is highest.
