Geneva (dpa) - The World Health Organisation once again declared Liberia Ebola-free, after no new case of the deadly virus was detected in the past 42 days.
The West African nation had already been pronounced free of Ebola in early May. But six new cases were reported a few weeks later, and the 42-day observation period began anew.
The situation also looked up in neighbouring Guinea and Sierra Leone, where a total of only nine new Ebola cases were reported in the past three weeks, according to WHO on Thursday.
The world's worst Ebola outbreak has so far infected more than 28 000 people, of who more than 11 300 died, mainly in Liberia, Sierra Leone and Guinea.
