Ebola is spreading
exponentially in Liberia, with thousands of new
cases expected in the
next three weeks, the World Health Organization (WHO) says.Conventional methods to control the outbreak were "not having an adequate impact", the UN's health agency added.
At least 2,100 people infected with Ebola have died so far in the West African states of Guinea, Liberia, Sierra Leone and Nigeria this year.
The WHO says 79 health workers have been killed by the virus.
Organisations combating the outbreak needed to scale-up efforts "three-to-four fold", the WHO said.
It highlighted Liberia's Montserrado county, where 1,000 beds were needed for infected Ebola patients but only 240 were available, leading to people being turned away from treatment centres.
Transmission of the virus in Liberia was "already intense", and taxis being used to transport infected patients appeared to be "a hot source of potential virus transmission", the WHO said.
"As soon as a new Ebola treatment facility is
opened, it immediately fills to overflowing with patients, pointing to a
large but previously invisible caseload," it added.
Three countries - Guinea, Sierra Leone and Liberia - are at the heart of the Ebola outbreak, but Liberia is suffering the most by far. Why this is the case is not completely understood. Finding the answer will be a critical part of tackling the outbreak.
Variations in burial practice - which can include touching the body and eating a meal near it - are being investigated.
There are also questions about trust in the authorities and how the risk of Ebola is being communicated. Riots erupted in the West Point slum, with some reports suggesting protesters believed Ebola was a hoax.
Another aspect is the state of the healthcare system, which was left in ruin by the civil war. Liberia had one doctor per 100,000 people before Ebola killed several staff.
The response has also been lacking. In the capital Monrovia there are 240 beds, but experts say they need more than 1,000. Patients without a bed have no choice but to go back home, where they may spread the virus.
