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.

Officials suspect the disease has caused 80 deaths in the Democratic Republic of Congo so far.

Some 88 people have died from the highly contagious haemorrhagic fever in the DR Congo, with one death in Uganda, and at least 336 suspected cases.
