The World Health Organization (WHO) has intensified emergency operations in eastern Democratic Republic of Congo after an Ebola outbreak caused about 136 deaths and more than 500 suspected cases.

The outbreak, centred in Ituri Province, is driven by the rare Bundibugyo strain of Ebola, which has no approved vaccine or treatment. Health officials warn the situation is spreading across multiple areas, with transmission likely underestimated due to insecurity and limited access.

WHO has deployed 12 tonnes of emergency medical supplies to Bunia, including protective equipment, isolation tents, and infection control materials. More than 40 medical experts have also been sent to support frontline response efforts.

The agency says the outbreak has already been declared a public health emergency of international concern, with concerns that it could last several months if not contained.

Cases have also been reported in neighbouring regions and across borders into Uganda, raising regional alarm.

Authorities say response efforts are being slowed by conflict, weak health infrastructure, and shortages of critical medical supplies, particularly in remote areas of eastern Congo.

International partners, including the United States, are increasing support through funding and emergency health measures, while WHO continues to warn that the outbreak may expand further before it is brought under control.
