The World Health Organization is issuing advice this Friday on new drugs that could stop the worst outbreak of Ebola.
Experts have been examining eight experimental treatments and two possible vaccines against the disease.
The charity Doctors Without Borders has so far called the response «lethally inadequate».
For its part, the US Agency for International Development announced that it is sending an additional US$75 million to the West African countries that have been hardest hit by Ebola.
The head of that agency, Rajiv Shah, told the BBC that the effort should focus on containing the outbreak that has already killed almost 2,000 people, 400 of them last week.
