At least seven patients infected with Ebola in Guinea have recovered from the virus and been allowed to return home, an international medical charity says.
Although the virus has a high mortality rate, a number of patients have managed to fight it off, Medecins Sans Frontieres has said.
There is no cure or vaccine for Ebola - one of the world's deadliest viruses.
But people have a better chance of surviving if it is identified early and they get supportive medical care.
So far this outbreak has killed more than two-thirds of those who have been infected, including 101 people in Guinea and 10 in neighbouring Liberia.
Ebola can kill up to 90% of those infected.
It is passed on through contact with the fluids of infected people or animals, such as urine, sweat and blood.
