Freetown - The deadliest Ebola outbreak ever is finally slowing in Liberia, the worst-hit country, but still wreaking havoc in two neighbouring west African states amid warnings of thousands of unreported deaths.
As the initially lacklustre global response to the crisis centred in Liberia and adjoining Sierra Leone and Guinea gathered some pace following repeated and impassioned appeals from top UN officials and world leaders, the good news from Liberia was tempered by warnings that the global toll is likely vastly underestimated.

The outbreak is officially thought to have claimed 4 960 lives and infected 13 042 people, according to the latest data issued by the World Health Organisation. But that could be the tip of the iceberg, an official at the UN health agency said.
"There are lots of missing deaths in this epidemic," Christopher Dye, WHO's strategy chief, told AFP, estimating that around 5 000 fatalities could be missing from the count.
This assessment, he said, was based on the knowledge that the fatality rate in the epidemic stands at about 70%.
Dye said the likely explanation was that many people were burying the dead in secret, possibly to avoid having authorities interfere with burial customs like washing and touching the deceased widely blamed for much of the transmission.
Sierra Leone's President Ernest Bai Koroma pressed the point in a meeting this week with lawmakers well as tribal and religious chiefs.
"You must enforce the law and take out the sick," he said, referring to a ban on traditional mourning rites with involve contact with corpses.
"This is time for action and you must stop the hypocrisy in the fight against Ebola," added Koroma, whose country has recorded 1 070 deaths from the disease and 4 759 cases.
Even though the spread of the virus has slowed in Liberia, where 2 697 people had died out of a total of 6 525 cases, officials warned that this is no time for complacency.
"We cannot wait. This is a situation where we're seeing progress but progress can be sporadic with this disease if we are not vigilant," said Ertharin Cousin, the head of the UN's World Food Programme this week while on a tour of west Africa.
"And one message is that now is the time for everyone to come together to ensure that we are meeting the needs of people who are affected by this disease, because we are seeing progress," Cousin said.

Among these are more than 2 000 children left orphans by the disease in Liberia alone, West Africa's regional bloc Ecowas said, urging international help to go beyond immediate medical care.
Anthony Banbury, the UN's pointman on the fight against Ebola, told the BBC that the international body had neither received sufficient funds nor the means to fight the disease.
"It's not here yet. There are still people, villages, towns [and] areas that [are] not getting any type of help right now and we definitely don't have the response capability on the ground now from the international community," he said.
The United Nations said it has received just over half - $572m of the $988m the funds it is seeking to finance the fight against the worst outbreak of Ebola since the discovery of the viral disease in 1976.
US President Barack Obama is asking Congress for more than $6.0bn in emergency funding while Japan became the latest country this week to pledge extra aid, taking Tokyo's contribution to a total of $140m.
