Mali is the latest area to be affected by possible cases of Ebola, prompting fears that the outbreak of the deadly virus is spreading across West Africa, Reuters reported.
Since the virus broke out in Guinea and Liberia, more than 90 fatal cases have been reported.
Both the countries have been warned about the Ebola disease turning into an unprecedented epidemic in an impoverished region with poor health services, Medecins Sans Frontieres, medical charity, said.
According to Reuters, operations have been locked down by foreign mining companies and some international staff in mineral-rich Guinea have also been pulled out.
People traveling, including doctors, have been put on alert in case they pick up the disease while moving to and from former colonies in the region.
After being placed in quarantine, three people's samples in Mali have been sent off to Atlanta for testing, the government said on state television late on Thursday.
"A high-speed intervention team has been created to follow the evolution of the situation on the ground," the statement said. Signs of improvement were being recorded in the three suspected victims' health report, it added.
According to Reuters, "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."
The death count has been counted to 85 people, with two more suspected victims of the virus being declared dead, Guinea's health ministry said. Liberia's death count has been up to seven people.
"We need to fight to contain it. A medical team from MSF came today to help train some of our health workers," said Liberia's health minister, Walter Gwenegale.
"The disease, which has killed 1,500 people 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," Reuters reported.
