WHO Says Ebola is Spreading "Exponentially" in Liberia WHO says Ebola is spreading exponentially in Liberia, with thousands of new cases expected in the next three weeks. Conventional methods to control the outbreak are not having an adequate impact. In the view of WHO organisations combating the outbreak need to scale-up efforts three-to-four fold. It highlighted Liberia's Montserrado county, where 1,000 beds are needed for infected Ebola patients but only 240 are available, leading to people being turned away from treatment centres. Transmission of the virus in Liberia is already intense, and taxis being used to transport infected patients appeared to be a hot source of potential virus transmission. As soon as a new Ebola treatment facility is opened, it immediately overflows with patients, pointing to a large but previously invisible caseload. The international response to the crisis has been stepped up, with the UK and US both promising to open new treatment centres in West Africa. BBC
