The Ebola outbreak in West Africa is "totally out of control,'' a senior official for Doctors without Borders has said.
Bart Janssens, the director of operations for the group in Brussels, told Associated Press on Friday that the medical group was stretched to the limit in its capacity to respond and that more help was needed if the outbreak was to be stopped.
"The reality is clear that the epidemic is now in a second wave,'' Janssens said. "And, for me, it is totally out of control.''
The outbreak, which began in Guinea either late last year or early this year, had appeared to slow before picking up pace again in recent weeks, including spreading to the Liberian capital for the first time.
Ebola has been linked to around 330 deaths in Guinea, Sierra Leone and Liberia, according to the latest numbers from the World Health Organization.
"I'm absolutely convinced that this epidemic is far from over and will continue to kill a considerable amount of people, so this will definitely end up the biggest ever,'' Janssens said.
