The African nation of Chad has said it will follow in South Africa's footsteps and introduce travel restrictions to countries suffering from the Ebola outbreak.
Prime Minister Kalzeubet Payimi Deubet said the country would close its border with Nigeria as part of efforts to prevent Ebola from entering the country.
He said the decision would have an "economic impact" on the region, but it was necessary for "public health needs".
It comes after South Africa banned entry to the country to all non-citizens travelling from Sierra Leone, Liberia and Guinea, while Liberia has quarantined entire neighbourhoods to try to stop the spread of the deadly virus.
