Congo had recorded 6,250 confirmed cases and 3,039 deaths by Sept. 1, according to the latest government figures. The outbreak has affected 60 health zones in six provinces. Authorities have also recorded 1,439 recoveries, while the case fatality rate stands at 48.6%.

Health authorities in the Democratic Republic of the Congo launched a targeted Ebola vaccination campaign in Kisangani, the capital of Tshopo Province, in an effort to curb the country’s deadliest outbreak of the disease on record. Frontline healthcare workers, emergency response personnel, and individuals who have had direct contact with confirmed cases are being prioritized during the initial phase of the deployment.

The European Commission has expanded its Ebola response with a €2.1 million purchase of PCR tests for the Bundibugyo virus outbreak. The agreement covers open-platform tests that laboratories can use with existing systems. Shipments are due to start in August as health teams confront a large outbreak centered in the Democratic Republic of the Congo and affecting parts of the wider region. The World Health Organization will receive the tests through its Hub for Global Health Emergencies Logistics in Dubai. WHO will then coordinate distribution to locations supporting the Ebola response. PCR testing allows laboratories to confirm infections and support surveillance around known cases.

Australian researchers from Adelaide University and the Olivia Newton-John Cancer Research Institute have identified a novel molecular switch that drives the spread of aggressive tumors. Published in EMBO Molecular Medicine, the breakthrough study reveals that Australian researchers uncover a promising new way to tackle triple-negative breast cancer by restoring a critical regulatory molecule known as miR-342. The discovery opens new avenues to prevent life-threatening secondary cancers in organs such as the lungs and bones.
