Tester -One-hundred thousand children vaccinated amidst one of the largest measles outbreaks in the world

On May 15, 2026, the Democratic Republic of Congo's Ministry of Health officially declared an Ebola disease outbreak in the northeast of the country, where Doctors Without Borders (MSF) teams are operating. Since then, authorities have reported nearly 500 suspected cases and more than 130 deaths across multiple health zones. On the same day, Uganda announced the virus had crossed its borders. The outbreak is caused by the Bundibugyo virus - rarer and one for which no vaccine or treatment has been approved yet. Here is what we know about the unfolding crisis in the DRC and Uganda.

Indiscriminate attacks on civilians and civilian structures – including bombing hospitals – forced recruitment, sexual violence, access constraints and shrinking humanitarian space are realities for people in South Sudan, as described by Doctors Without Borders (MSF) in their report on escalating violence in the country, “They Killed Them While We Were Running”. The report details that a total of 12 attacks on MSF staff and facilities left an estimated 762,000 people without access to healthcare between January 2025 and April 2026.

Following the official declaration of an Ebola Virus Disease outbreak by the Ministry of Health in the Democratic Republic of Congo on 15 May, Doctors Without Borders (MSF) is preparing to rapidly scale up its medical response in Ituri province, in the country’s northeast.
