The Malian government has confirmed the first case of Ebola in the country.
It said a two-year-old girl had tested positive for the haemorrhagic virus. Reports say she recently returned from the neighbouring Guinea.
More than 4,800 people have died of Ebola – mainly in Liberia, Guinea and Sierra Leone – since March.
Meanwhile, an international team of scientists has been set up to determine the effectiveness of using the blood of Ebola survivors as a treatment. It is hoped the antibodies used by the immune system to fight Ebola can be transferred from a survivor to a patient.The study will start in Guinea and is led by the Institute of Tropical Medicine in Antwerp, Belgium. The European Union has given 2.9m euros (£2.3m) to fund the project.
