The World Health Organization is beginning a two day emergency meeting to discuss new measures to tackle the Ebola virus.
The disease, for which there is no vaccine and no cure, has claimed more than 800 lives since the current outbreak began in February.
Meanwhile British Airways has suspended flights to Liberia and Sierra Leone because of the virus.
