Summary of the INSP bulletin, with each new release
The bulletin of 4 Sep 2026, published 5 Sep 2026, reports 86 new confirmed cases and 39 deaths. 86 cases is in line with the seven-day average of 82.4 a day. There is 1 new zone affected: Kayna (Nord-Kivu); the outbreak now affects 61 zones in 6 provinces.
01The toll
Since the outbreak began, 6,522 confirmed cases and 3,134 deaths: 48.1% of patients have died. 1,516 people have recovered. 21 more than the day before. 817 patients are hospitalised in Ebola treatment centres. Over the past seven days, an average of 82.4 cases and 38.9 deaths a day, against 69.6 cases and 36.6 deaths the week before.
02Where
Ituri accounts for 53 of the 86 new cases. Then Nord-Kivu with 31 and Haut-Uélé with 2. The other 3 provinces report none. 5 zones carry 51 of these 86 cases: Bunia 16, Katwa 13, Mangala 9, Musienene 7 and Komanda 6. 52 of the 61 affected health zones reported at least one new case in the past three weeks; 9 reported none.
03Deaths
Of the 39 deaths reported today, 30 occurred in the community, that is outside a treatment centre, and 9 in a treatment centre. Deaths outside a centre: 16 in Ituri and 14 in Nord-Kivu. Those in a treatment centre: 7 in Ituri, 1 in Nord-Kivu and 1 in Haut-Uélé. The 7 in Ituri have not yet been assigned to a specific health zone, like 354 deaths before them.
04The response
2,144 reports of possible patients ("alerts") were received; 1,955 were checked and 399 retained as suspected cases, to be tested. Of 575 samples tested in the laboratory, 86 were positive, that is 15.0 %. 86.0 % of the people who had been close to a patient (the "contacts") were seen by follow-up teams, above the 85% threshold the INSP has set itself. Fewer than three contacts in four were seen in the following provinces: Bas-Uélé, Haut-Uélé and Tshopo. Ebola treatment centres are 59.4 % full: 817 patients for 1,376 beds. Beyond capacity: Nord-Kivu, 237 patients for 220 beds. Safe burials, carried out by protected teams to avoid contagion: 124 deaths reported, 105 burials carried out, 96 bodies tested. Around new cases, 12 prevention rings were set up out of 41 expected, that is the disinfection of the home and the follow-up of relatives. Vaccination: 1,861 people have received the Ervebo vaccine since the campaign began on 26 Aug 2026: 1,375 in Tshopo (figure of 3 Sep 2026) and 486 in Bas-Uélé. At control points on roads and at borders, 267,016 travellers passed through and 98.1 % had a temperature check.
05The difficulties encountered
In Ituri, prevention rings are set up around only 29% of new cases (12 of 41), teams are lacking in Fataki, Mangala and Nizi; 21 patients refused to be hospitalised, 7 bodies could not be tested because families objected; the treatment centre of the CME hospital in Bunia is full for confirmed patients, those of Nizi, Lita, Mambasa and Logo for suspected patients, and the extension of Nizi and Bambu is delayed. In Nord-Kivu, patients are treated in facilities not meant for Ebola; a confirmed patient ran away in Katwa, another in Lubero refuses to go to the transit centre, and residents threaten to burn the centre under construction in Katwa. In Bas-Uélé, no prevention ring set up, neither a centre up to standard nor an ambulance, the waste-treatment area of the Buta hospital does not work, the Ganga and Viadana hospitals do not sort patients at the entrance, vaccination teams have no vehicle and six zones have no plan to vaccinate health workers; control points did not send their figures. In Tshopo, residents' opposition and untraceable addresses prevent prevention rings around the last three patients, blood for transfusions is still lacking, 12 of 30 control points are working and three zones have no psychological support worker. Contact follow-up lacks teams.
