Ebola virus: Guinea shuts Liberia and S Leone borders

                           

Guinea has closed its borders with Liberia and Sierra Leone to contain the spread of Ebola, which has killed 959 people in the three countries.

The latest outbreak is thought to have begun in Guinea, but Liberia and Sierra Leone are currently facing the highest frequency of new cases.

The World Health Organization (WHO) said on Friday the spread of the virus was a global health emergency due to rate at which the virus is spreading. Nigeria is said to have record few cases of Ebola transmission.
