The Democratic Republic of Congo is braced for a gruesome battle, this time against the deadly virus Ebola. Congolese authorities declared the outbreak in the northwest region on 8 May; so far three have died from the disease. The number of reported cases is 42, according to a World Health Organisation tally. A health ministry spokeswoman said that 5,400 doses of vaccine had arrived from Geneva; they would be kept in Kinshasa until refrigerated transport could be guaranteed. The WHO said the risk of the disease spreading was high, and announced it was preparing for the ‘worst case scenario’. Its chief executive visited the affected area last weekend, saying he hoped for a ‘better way out’ of the latest outbreak. On 16 May Oxfam pledged an initial £50,000 to fight the spread of the disease. Ebola is one of the world's most notorious diseases, being both highly infectious and extremely lethal. See also:
