The World Health Organization declared the Ebola disease outbreak caused by a rare virus in Congo and neighboring Uganda a public health emergency of international concern on Sunday, after more than 300 suspected cases and 88 deaths.
The WHO said the outbreak does not meet the criteria of a pandemic emergency like COVID-19, and advised against the closure of international borders.
The WHO said on X that a laboratory-confirmed case has also been reported in Congo’s capital, Kinshasa, which is about 1,000 kilometers (620 miles) from the outbreak’s epicenter in the eastern province of Ituri, suggesting a possible wider spread. It said the patient had visited Ituri and that other suspected cases have also been reported in North Kivu province, which is one of Congo’s most populous and borders Ituri.
Ebola is highly contagious and can be contracted via bodily fluids such as vomit, blood or semen. The disease it causes is rare, but severe and often fatal.
The WHO’s emergency declaration is meant to spur donor agencies and countries into action. By the WHO’s standards, it shows the event is serious, there is a risk of international spread and it requires a coordinated international response.
The global response to previous declarations has been mixed. In 2024, when the WHO declared mpox outbreaks in Congo and elsewhere in Africa a global emergency, experts at the time said it did little to get supplies like diagnostic tests, medicines and vaccines to affected countries quickly.
Health authorities say the current outbreak, first confirmed on Friday, is caused by the Bundibugyo virus, a rare variant of the Ebola disease that has no approved therapeutics or vaccines. Although more than 20 Ebola outbreaks have taken place in Congo and Uganda, this is only the third time the Bundibugyo virus has been detected.
