Ebola outbreak: Liberia has no new cases for a week
Liberia has gone a week without reporting any new cases of Ebola, the first time such a milestone has been reached since May 2014, the World Health Organization says, the BBC reports.
But officials say there have been 132 new cases in Guinea and Sierra Leone in the week to 1 March.
They have warned that populations are so mobile in the area that there could easily be fresh outbreaks in Liberia.
Nearly 10,000 people have died from Ebola, most in these three countries.
"We look at the three countries as really a single country, so while it's good news that Liberia itself has no new cases, the populations are so mobile in that region that there could easily be re-importations of cases," said WHO spokesman Gregory Hartl.
"We have to get down to zero in all three countries before we can consider this thing beaten."
Medics are now getting ready to discharge the country's last confirmed Ebola patient in the Liberian capital Monrovia.
The country has to have no new cases for 42 days to be declared Ebola-free.
