West Africa is facing the largest Ebola outbreak in history and more than 2,000 people have died. | |

Blood medicine | |
People produce antibodies in the blood in an attempt to fight off an Ebola infection. | |
In theory, those antibodies can be transferred from a survivor into a sick patient to give their immune system a boost. | |
However, large scale data on the effectiveness of the therapy is lacking. | |
Studies on the 1995 outbreak of Ebola in Democratic Republic of Congo showed seven out of eight people survived after being given the therapy. | |
Dr Marie Paule Kieny, an assistant director general at WHO said: "We agreed that whole blood therapies may be used to treat Ebola virus and all efforts must be invested to help infected countries to use them. | Dr Marie Paule Kieny, an assistant director general at WHO said: "We agreed that whole blood therapies may be used to treat Ebola virus and all efforts must be invested to help infected countries to use them. |
"There is a real opportunity that a blood-derived product can be used now and this can be very effective in terms of treating patients." | |
She said that it was the one positive aspect of so many people being infected. | |
"There are also many people now who have survived and are doing well. They can provide blood to treat the other people who are sick." | |
Vaccines | |
There is no clinically proven drug or vaccine to treat Ebola, but many are in the experimental stage. | |
Around 150 experts have spent the last two days investigating how to fast-track promising experimental drugs to make them available in West Africa as soon as possible. | |
Ebola vaccine trials started in the US this week and will be extended to centres in the UK, Mali and Gambia in the coming weeks. | |
The WHO said safety data would be ready by November 2014 and, if it proved safe, would be used in West Africa immediately. | |
Healthcare workers and other frontline staff would be prioritised for vaccination, the WHO said. | |
Experimental drugs - such as ZMapp, which has been used in seven patients including a British volunteer nurse - were also assessed. | |
However, the supplies of all the experimental drugs are very limited, if not exhausted. | |
The WHO said efforts were underway to increase production, but it would take several months. | |
Dr Jesse Goodman, from Georgetown University Medical Center in the US, took part in the meeting. | |
He said: "This is a unique opportunity to identify what new treatments and vaccines can really help people and then potentially accelerate their use. | |
"We don't want to end up after this outbreak not knowing how best to prevent or treat the next one." | |
Yet the WHO warned that all the talk of experimental therapies must not detract from the proven methods of infection control which have defeated all previous outbreaks. | |
Meanwhile, officials in Nigeria have decided to reopen schools in the country from 22 September. | |
They were closed as a precaution to prevent the spread of the virus. | |
