A haemorrhagic fever of unknown origin has killed 13 people in the northwestern Democratic Republic of Congo since August 11, a health ministry official said.
"All 13 people who have died suffered from a fever, diarrhoea, vomiting and, in a terminal stage, of vomiting a black matter," said Dr Felix Kabange Numbi. So far, about 80 people who came into contact with the deceased have been admitted to hospital.
