On 22 May WHO assesses the risk posed by the outbreak as very high at the national level in the DRC, high at the regional level and low globally. The same day the IHR Emergency Committee, first convened by the Director-General on 19 May, issues its temporary recommendations to States Parties.

After consulting the States Parties where the event is occurring, the WHO Director-General determines on 17 May that Ebola disease caused by Bundibugyo virus in the DRC and Uganda constitutes a Public Health Emergency of International Concern (PHEIC) under the International Health Regulations (2005). Response measures include rapid response teams, medical supplies, strengthened surveillance, laboratory confirmation and infection prevention and control.

Uganda confirms two cases imported from the DRC: an elderly man who died in Kampala on 14 May and was confirmed on 15 May, and a second, unrelated case confirmed on 16 May.

The DRC Ministry of Public Health declares its 17th Ebola outbreak, in the Rwampara, Mongbwalu and Bunia health zones. As of 15 May a total of 246 suspected cases and 80 deaths (four among confirmed cases) are reported from those three Ituri health zones — Rwampara (six health areas affected), Mongbwalu (three) and Bunia. Uganda confirms an outbreak the same day after identifying an imported case. Case fatality in the two earlier Bundibugyo outbreaks, in Uganda in 2007 and the DRC in 2012, ranged from about 30% to 50%, and unlike Zaire ebolavirus there is no licensed vaccine or specific therapeutic for Bundibugyo virus.

At the Institut National de Recherche Biomédicale (INRB) in Kinshasa, eight of the 13 samples sent from Ituri test positive for Ebola disease on 14 May, and the strain is identified as Bundibugyo — the DRC's 17th Ebola outbreak. Preliminary tests in Bunia had been negative for Zaire ebolavirus, dengue, rotavirus, cholera, malaria, plague, mpox and COVID-19.

Ituri, to 14 May: the outbreak's first 8 confirmed cases, 4 of them fatal, in the Mongbwalu, Rwampara and Bunia health zones (INSP report N°1).

WHO receives an alert on 5 May about an unknown illness with high mortality in Mongbwalu Health Zone, Ituri Province, including four health workers who died within four days. The first currently known suspected case, a health worker, had symptom onset on 24 April and died at a medical centre in Bunia. Twenty samples tested at the provincial public health laboratory in Bunia are negative for Ebola (Zaire) virus, so samples are sent to INRB in Kinshasa. By 15 May, 24 suspected cases are in isolation across the Rwampara, Mongbwalu and Bunia health zones.
