A senior official for Doctors Without Borders says the Ebola outbreak ravaging West Africa is "totally out of control" and that the medical group is stretched to the limit in its capacity to respond.

Bart Janssens, the director of operations for the group in Brussels, said Friday that international organizations and the governments involved need to send in more health experts and increase public education messages about how to stop the spread of the disease.

Janssens said the outbreak is far from over and will probably end up as the most deadly on record.

According to the latest figures from the World Health Organization, Ebola has already been linked to more than 330 deaths in Guinea, Sierra Leone and Liberia.
