The World Health Organization says the death toll from the Ebola outbreak in West Africa is now at least 1,350 people.
The latest figures Wednesday show that the deaths are mounting fastest in Liberia, which now accounts for at least 576 of the deaths.
The U.N. health agency also warned in its announcement that "countries are beginning to experience supply shortages, including fuel, food, and basic supplies."
This comes after a number of airlines and shipping services have halted transport to the worst affected capitals of Liberia, Sierra Leone and Guinea.
In a desperate bid to halt the disease's spread, authorities in Liberia have quarantined off a huge slum that is home to 50,000 people. Protests erupted in West Point on Wednesday, where residents threw rocks at police.
