With more than 60 outbreak hotspots spread across the region, medical NGO Doctors Without Borders (MSF) has warned that the recent outbreak of the deadly Ebola virus in West Africa is 'out of control'.
"The scale of the current Ebola epidemic is unprecedented in terms of geographical distribution, people infected and deaths," MSF said in a statement.
The rapid spread of the disease, which is deadly in up to 90 percent of cases, has overwhelmed aid agencies and health workers and terrified local communities.
"The epidemic is now out of control," said Bart Janssens, MSF director of operations. "With the appearance of new sites in Guinea, Sierra Leone and Liberia, there is a real risk of it spreading to other areas."
After the first reported cases in Guinea at the start of the year, at least 337 people have died from Ebola in the three countries in 2014, according to data released last week by the World Health Organization.
The incurable disease is spread by contact with bodily fluids including sweat, meaning just touching an infected person is enough to spread the virus.
MSF called for a "massive deployment" of medical resources by governments in the region to curb the epidemic.
"We have reached our limits," Janssens said. "We are no longer able to send teams to the new outbreak sites."
Ebola can fell its victims within days, causing severe fever and muscle pain, weakness, vomiting and diarrhoea -- in some cases shutting down organs and causing unstoppable bleeding.
This is the first time the disease has spread through the region and MSF said it had identified more than 60 separate locations with confirmed cases of the virus.
"Ebola is no longer a public health issue limited to Guinea: it is affecting the whole of West Africa," Janssens said.
