Ebola Bundibugyo: ECDC updates, 7,200 confirmed cases and 3,475 deaths in DR Congo
Compared with the ECDC report of September 11, the Congolese bulletin of the 13th adds 258 confirmed cases and 126 deaths. The affected health zones are 62 out of 167 across seven provinces.
During the day a new update arrived on the Bundibugyo virus disease outbreak in the Democratic Republic of Congo, following the report from the European Centre for Disease Prevention and Control of September 11. That is the reason we return to the story.
On September 13 the Congolese health authorities published a bulletin, taken up by the ECDC, with 7,200 confirmed cases and 3,475 related deaths, on data up to September 12. Compared with the ECDC report of September 11 the increase is 258 confirmed cases and 126 deaths. The numbers are rising, and we publish them explicitly indicating the direction of the movement and the reference date of each reading, because in an ongoing epidemic a figure without its date means nothing.
| Indicator | Data as of September 12 |
|---|---|
| Confirmed cases | 7,200 |
| Related deaths | 3,475 |
| New cases since the September 11 report | 258 |
| New deaths since the September 11 report | 126 |
| Patients hospitalized in isolation | 923 |
| Identified contacts under monitoring | 88% |
| Affected health zones | 62 out of 167, in seven provinces |
What the operational indicators say
Two figures describe response capacity more than the total case count does. The first is the number of hospitalizations in isolation, 923: it is the snapshot of the burden the facilities are bearing at a given moment. The second is the share of identified contacts under monitoring, 88%: in surveillance of a filovirus epidemic, the percentage of contacts followed is the indicator that signals whether the transmission chain is being tracked or is slipping away. The figure does not say how many contacts there are in total, nor how many remain outside tracking in absolute terms.
The geographic extent covers 62 of the country’s 167 health zones, spread across seven provinces: just over a third of the health zones are affected.
The Ugandan precedent
In the regional context, the ECDC recalls the situation in Uganda, where between May and June 2026, 20 cases were reported. On August 25 the World Health Organization declared that outbreak over, after 42 days without new confirmed cases: this is the observation period set for declaring the end of an outbreak of this type, equal to double the maximum incubation period.
Risk for Europe and available tools
According to ECDC models, the risk of importation into the European Union and the European Economic Area from the affected area remains very low. This is an assessment by a European agency, updated to the bulletin in question, not a definitive forecast.
On the matter of tools, the WHO states that for the Bundibugyo species of the Ebola virus there are no vaccines or specific treatments. We report this information as the position of the international health organization and in its own terms: it is data on the state of available tools, not a clinical indication, and this newspaper does not formulate one.
What we do not know
We do not know the day-by-day trend of new cases: the difference between two bulletins two days apart does not allow us to establish whether the curve is accelerating or slowing. We do not know how many people have recovered and been discharged, a figure absent from the available data. We do not know which the seven affected provinces are or how cases are distributed among them. The next verifiable element will be the next bulletin from the Congolese Ministry of Health and its inclusion in the ECDC’s epidemiological update.
