At least 61 people have died after contracting a mystery illness in Guinea.
Six out of 12 samples analysed have tested positive for Ebola.
The disease is most commonly found in the Democratic Republic of Congo, Uganda and South Sudan.
This is the first time Ebola has been recorded in Guinea.
Meanwhile, a man is in hospital in Canada with Ebola-like symptoms. He had recently returned from Liberia. He’s in isolation and said to be in critical condition.
Doctors Without Borders (MSF) said researchers are trying to pinpoint the source of the highly contagious virus.
The charity is flying medicine and equipment to Guinea in response to the outbreak.
