Countries across Africa and beyond are intensifying measures to prevent and control the latest Ebola outbreaks in Central and East Africa, which have killed more than 100 people, following the World Health Organization's declaration of a public health emergency of international concern.

DR Congo's Health Minister Samuel Roger Kamba said on Tuesday that the death toll had risen to 131, with 513 suspected Ebola cases. Uganda has so far reported two confirmed cases and one death.

The outbreaks, linked to the Bundibugyo strain of the Ebola virus, have triggered heightened surveillance, emergency preparedness and border screening measures across the region.

Africa CDC warned that insecurity in eastern DR Congo, mining-related mobility, weak infection prevention systems and intense cross-border movement near Uganda, Rwanda and South Sudan could accelerate the spread of the virus if response efforts are not strengthened quickly.
