Measures are being taken in West Africa to prevent the spread of the Ebola virus after an outbreak in Guinea.
It was reported that the authorities in Mauritania closed its border with Senegal and Mali due to fears of infection.
The Ministry of Health in Guinea banned the sale of bats because the animals carry the virus.
