Ebola infections in West Africa reach almost 1000Listen /
An estimated 964 cases of Ebola have been reported in Guinea, Liberia and Sierra Leone, the World Health Organization (WHO) has reported.
So far, more than 600 people have died from the virus.
In Guinea alone, six new cases and three deaths have been reported in the last few days.
The disease causes severe haemorrhaging and can kill up to 90 per cent of those infected.
It's spread by direct contact with the blood and body fluids of infected animals or people.
UN Spokesperson, Farhan Haq, says WHO is following developments closely.
"The organization is monitoring the situation and increasing its efforts to reduce the number of cases. A new Sub-Regional Coordination Centre in Conakry is being set-up to help control and coordinate response efforts in the three countries." (11″)
There are no known cures or preventative vaccines for Ebola, although outbreaks don't generally lead to large scale infections.
