An Ebola outbreak in Guinea in west Africa has put six bordering nations on alert, while the World Health Organization has begun a mass vaccination programme.
So far, 18 people have contracted the virus and nine have died.
In neighbouring Liberia, they have begun preparing for the worst again. Only seven years ago the virus came across the Guinea border and nearly 5,000 people died.
The survivors still bear the mental and physical scars and this latest outbreak is bringing back difficult memories.
This is our second special report from Liberia.
