According to BBC report two-year-old girl had tested positive for the haemorrhagic virus. 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.
