Mali said it had identified its first possible cases of Ebola since the start of an outbreak in neighboring Guinea, adding to fears that the deadly virus was spreading across West Africa.

 

More than 90 people have already died in Guinea and Liberia in what medical charity Medecins Sans Frontieres (MSF) has warned could turn into an unprecedented epidemic in an impoverished region with poor health services.

 

Foreign mining companies have locked down operations and pulled out some international staff in mineral-rich Guinea. French health authorities have also put doctors and hospitals on alert in case people travelling to and from former colonies in the region pick up the disease.

 

Three people in Mali had been placed in quarantine and samples sent off to Atlanta in the United States for tests, the government said on state television late on Thursday.

 

The latest outbreak originated in Guinea two months ago and has since spread to its neighbors Sierra Leone and Liberia. Gambia has placed two people in quarantine although the health ministry since said the cases were negative.

 

Many health systems in West Africa are poorly equipped to deal with an epidemic and aid workers have warned of the difficulty of fighting infections scattered across several locations and in densely populated areas such as Guinea's capital Conakry.

 

Guinea's health ministry said that two more suspected victims of the virus had died, bringing its death count to 86. Liberia also reported three new deaths among its suspected 14 cases, raising its death toll to seven.

 

The disease, which has killed 1,500 since it was first recorded in 1976 in what is now Democratic Republic of Congo, causes vomiting, diarrhea and external bleeding. It has a fatality rate of up to 90 percent.
