The move came as Liberia said it was getting an experimental drug, Zmapp, after requests to the US government. But officials warned there were very limited supplies of potential treatments.
The WHO said where experimental treatments are used there must be informed consent and the results of the treatment collected and shared.The WHO said where experimental treatments are used there must be informed consent and the results of the treatment collected and shared.

But the WHO said there were only 12 doses.
Zmapp has been used on two US aid workers who have shown signs of improvement, although it is not certain what role the medication played in this.Zmapp has been used on two US aid workers who have shown signs of improvement, although it is not certain what role the medication played in this.

Only one drug has moved onto early safety testing in humans. Known as TKM-Ebola this interrupts the genetic code of the virus and prevents it from making disease causing proteins.Only one drug has moved onto early safety testing in humans.

The drug was trialled in healthy volunteers at the beginning of 2014 but the American medicines regulator asked for further safety information. The manufacturer says human studies may soon resume.The drug was trialled in healthy volunteers at the beginning of 2014 but the American medicines regulator asked for further safety information.

Vaccines to protect against acquiring the disease have also been shown to work in primates. American authorities are considering fast-tracking their development and say they could be in use in 2016. Another option would be to use serum from individuals who have survived the virus - this is a part of the blood that may contain particles able to neutralise the virus.

But experts warn ultimately the only way to be sure a drug or vaccine is effective is to see if it works in countries affected by Ebola.But experts warn ultimately the only way to be sure a drug or vaccine is effective is to see if it works in countries affected by Ebola.

Ebola's initial flu-like symptoms can lead to external haemorrhaging from areas like eyes and gums, and internal bleeding which can lead to organ failure. Patients have a better chance of survival if they receive early treatment.Ebola's initial flu-like symptoms can lead to external haemorrhaging from areas like eyes and gums, and internal bleeding which can lead to organ failure.
