The World Health Organization warns the outbreak of a rare Ebola strain in the Democratic Republic of the Congo and Uganda is likely larger than reported

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.

An Ebola outbreak in the Democratic Republic of the Congo and Uganda constitutes a "public health emergency of international concern," the World Health Organization said.
