Ebola virus behind massive outbreak in DRC could be mutating, officials say

The head of the World Health Organization, Tedros Adhanom Ghebreyesus, has arrived in Congo to support efforts to slow the world's fastest-growing Ebola outbreak, which has reached nearly 4,000 confirmed cases. This is his second visit since the outbreak was declared in mid-May. As of Monday, there have been 3,874 cases and 1,751 deaths. The outbreak is spreading faster than the response, with many new cases occurring outside of monitored contacts. Challenges include inaccessible areas due to rebel conflict, health worker strikes, and ineffective contact tracing, with 60-70% of new cases not linked to known contacts. The Bundibugyo virus has no approved treatment or vaccine, contributing to a 45% fatality rate.

The Democratic Republic of the Congo's Ebola outbreak, primarily concentrated in the Ituri province, has resulted in over 1,700 deaths out of 3,802 recorded cases since May 15. This epidemic, caused by the Bundibugyo strain, is the second-largest and fastest-growing on record, with no approved vaccines or treatments for this variant. The World Health Organization (WHO) is accelerating trials for experimental treatments, preventive medicines, and vaccines, benefiting from advance planning that allows for quicker testing compared to previous outbreaks. Over 17,000 contacts are being monitored daily. WHO Director-General Tedros Adhanom Ghebreyesus is visiting the region to assess the situation, while the peak of the outbreak remains uncertain.

Eastern Congo is experiencing its fastest-growing Ebola outbreak, which has resulted in over 1,700 deaths out of 3,802 recorded cases. The outbreak, declared on May 15 and linked to the Bundibugyo virus, is primarily concentrated in Ituri province but has spread to five other provinces. A significant challenge is that nearly 80% of new cases stem from community spread rather than contact tracing, exacerbated by delays, access difficulties, community mistrust, and violence. The World Health Organization Director-General is visiting the region this week. Efforts to control the outbreak are further hindered by a funding gap, attacks on health centers, ongoing conflict, and unpaid wages for healthcare workers, with over 100 health workers infected. Clinical trials for treatments and vaccines are underway.

The World Health Organization (WHO) has declared the current Ebola outbreak in the Democratic Republic of Congo (DRC) the largest in the country's history. As of July 30, 2026, the outbreak, caused by the Bundibugyo strain, has resulted in 3,605 confirmed cases and 1,587 deaths, with a fatality rate of 44%. This surpasses the previous largest outbreak in the DRC, which occurred between 2018 and 2020. The WHO stated the outbreak is intensifying with sustained transmission and increasing cases and deaths. Currently, there is no approved vaccine or treatment for this strain, though development is underway. Ebola, a disease spread through bodily fluids, has caused 15,000 deaths across Africa in the past 50 years.

The Ebola epidemic in the Democratic Republic of the Congo (DRC) has become the world's second largest outbreak on record, with over 3,500 confirmed cases. Officials have declared it the fastest spreading Ebola epidemic ever seen and are urging the world to pay more attention. The outbreak, caused by the rare Bundibugyo strain for which there is no approved vaccine or treatment, has resulted in 1,556 deaths, a case fatality rate of 44.1 percent. This outbreak began less than three months ago and has already killed five times as many people as previous outbreaks had by the same stage. Medical personnel are facing challenges including insecurity and attacks on health facilities in eastern DRC, alongside significant foreign aid cuts.

The Democratic Republic of the Congo is experiencing its fastest-growing Ebola outbreak in history, with over 3,360 confirmed cases and 1,487 deaths across five eastern provinces. This outbreak of the Bundibugyo strain, declared on May 15th, is complicated by ongoing conflict in affected areas, hindering health responses. Health officials estimate a 45% case fatality rate and note that new infections continue to rise weekly. While clinical trials for a vaccine began in early July, they could take up to four months. Experts emphasize the need for public cooperation and continued efforts to contain the spread, which was detected late.

The Ebola outbreak in the Democratic Republic of the Congo (DRC) has surpassed 1,500 deaths, with over 3,442 cases recorded. This represents a significant increase in fatalities over the past week, as authorities struggle to contain the virus's spread, particularly in the eastern regions. The outbreak is exacerbated by ongoing conflict, which hinders government control and infrastructure, and the lack of a proven vaccine for the Bundibugyo strain of Ebola. Delays in contact tracing, access challenges, and community mistrust have further complicated response efforts. While mostly concentrated in Ituri province, cases have been confirmed in five other provinces, including Kisangani. Neighboring Uganda has declared its Ebola outbreak over.

The fastest-growing Ebola outbreak in history has killed over 1,500 people in eastern Congo as of Thursday, with cases reaching 3,442. This represents a 50% increase in about a week, indicating response efforts are being outpaced. The outbreak, declared May 15, is caused by the Bundibugyo virus, for which there are no approved vaccines or treatments. Displacement due to conflict and illegal mining, coupled with attacks on health facilities and misinformation, are hindering contact tracing and response efforts, particularly in Ituri province. International partners temporarily withdrew from some areas following an attack, disrupting surveillance and supplies.

Uganda has declared an end to its Ebola outbreak after successfully completing a mandatory 42-day monitoring period following the discharge of the last national patient on June 16, 2026. Health Minister Chris Baryomunsi announced that nationwide surveillance detected no new cases. Despite this declaration, the minister urged the public to remain alert and continue observing public health measures. The outbreak in Uganda involved 20 confirmed cases, with 18 discharged and two deaths, both of whom were from the Democratic Republic of the Congo (DRC). Neighboring DRC is experiencing a much larger and faster-spreading outbreak of the Bundibugyo Ebola strain, which currently lacks approved vaccines or treatments.

Uganda has declared itself free of Ebola after its last patient was discharged in mid-June. The outbreak, linked to a larger one in neighboring Congo, began with Congolese individuals crossing the border seeking treatment. Ugandan authorities confirmed two cases, including one death, on May 15, the same day Congo declared its outbreak. The Ministry of Health stated that Uganda is free of Ebola because all identified contacts were quarantined and completed follow-up without further transmission, and enhanced surveillance detected no unexplained community spread. The Bundibugyo type of Ebola virus, responsible for this outbreak, has no approved vaccine or treatment. Meanwhile, the Ebola outbreak in Congo remains a global health emergency, with over 3,200 cases and 1,400 deaths reported.

The Democratic Republic of Congo's current Ebola outbreak has reached 3,262 confirmed cases, according to the ministry of health. This figure is nearing the total of the country's largest recorded outbreak from 2018-2020, which saw over 3,400 cases. Of the current cases, 1,437 have resulted in death. Officials have described this outbreak as the fastest on record and it is primarily concentrated in the eastern Ituri province. The previous major outbreak, which also affected neighboring Uganda, lasted approximately two years and resulted in over 2,200 deaths.

The Democratic Republic of the Congo is experiencing a significant surge in its 17th Ebola outbreak, with cases now totaling 3,200 and resulting in at least 1,405 deaths. In just ten days, infections have increased by approximately 1,000, and the virus has spread across five provinces, with nearly 90 percent of cases concentrated in the northeastern province of Ituri. This outbreak, caused by the Bundibugyo strain for which there is no approved vaccine or treatment, is proving difficult to contain. Humanitarian efforts, including the transport of aid workers and samples by the UN Humanitarian Air Service, are crucial but face logistical challenges. Strikes by healthcare workers over unpaid wages have also hampered response efforts. Scientists are actively developing vaccines and treatments, with an experimental vaccine recently administered to a volunteer group.

The Ebola outbreak in the Democratic Republic of Congo (DRC) has surpassed 1,309 deaths and 2,973 confirmed cases, marking the fastest-spreading Ebola epidemic on record. This surge, a 40% increase in deaths in five days, is attributed to the rare Bundibugyo variant, which currently lacks approved vaccines or treatments. The epidemic is exacerbated by active hostilities and a shortage of public health resources. Scientists are developing an experimental vaccine, with the first dose administered to a volunteer. The outbreak's rapid progression, reaching 1,000 deaths in under 10 weeks, threatens to become the worst in history if not contained. Health workers are striking over unpaid wages and unsafe conditions, further hindering response efforts.
