The Ebola outbreak in the Democratic Republic of Congo made the long-feared jump across borders with three cases confirmed in Uganda, including the death of a five-year-old boy. Concern has been mounting that this would happen, underscored by an increase in the number of cases in recent weeks. The World Health Organisation and Ugandan health authorities said the Congolese boy had travelled to Uganda with his family. The other two confirmed cases are the boy's three-year-old brother and his grandmother, 50. They are in isolation at a Ugandan Ebola treatment unit. Eight people who had been in contact with the family are being traced. The Congo outbreak is the second largest and second deadliest in history. The Wellcome Trust said, ’This epidemic is in a truly frightening phase and shows no sign of stopping any time soon.’ WHO is expected to come under pressure to declare an international health emergency.
