Liberia, already hardest-hit by the Ebola epidemic sweeping West Africa, should be prepared for thousands of new cases in coming weeks, the World Health Organization has warned.
The country already accounts for a significant amount of Ebola-related deaths across West Africa.
WHO noted that motorbike-taxis and regular taxis are "a hot source of potential virus transmission" because they are not disinfected in Liberia, where conventional Ebola control measures "are not having an adequate impact".
The health agency said aid partners must significantly intensify efforts to combat Ebola in Liberia and elsewhere in West African countries battling the epidemic.
1,089 people have died from the virus out of 1,871 cases in Liberia, which has reported confirmed cases in 14 out of 15 counties.
A total of 2,097 people have died out of 3,944 Ebola cases, across Guinea, Liberia and Sierra Leone
Another 18 cases and seven deaths have been recorded in Nigeria and one non-fatal case in Senegal.
"The number of new cases is moving far faster than the capacity to manage them in Ebola-specific treatment centres," the UN health agency said in a statement.
In an attempt to curb the spread of the disease the Liberian government is to extend a nationwide curfew, imposed last month.
Today it was announced Britain is to set up a 62-bed medical centre to treat Ebola patients in Sierra Leone.
The centre will be based near the capital Freetown and will be opened in eight weeks' time, according to an international development secretary.
It will be built and operated by military engineers and medical staff.
Sierra Leone last week ordered a four-day countrywide ’lockdown’ starting 18 September as part of tougher efforts to halt the spread of Ebola.
