Winnipeg, Manitoba, Canada The past year has marked the most devastating Ebola outbreak the world has ever witnessed, with over 28,000 cases and over 11,000 deaths. Ebola virus (EBOV) has now been around for almost 50 years. In this review, we discuss past and present outbreaks of EBOV and how those variants evolved over time. We explore and discuss selective pressures that drive the evolution of different Ebola variants, and how they may modify the efficacy of therapeutic treatments and vaccines currently being developed. Finally, given the unprecedented size and spread of the outbreak, as well as the extended period of replication in human hosts, specific attention is given to the 2014–2015 West African outbreak variant (Makona).

The final 68 people who had been in contact with an Ebola patient were released from quarantine on Saturday, said a senior health official, raising hopes of an end to the disease in the last West African country with confirmed cases.

The world's worst Ebola epidemic, which hopped borders to kill more than 11,300 people and devastate already fragile West African economies, has already been declared over in Liberia and Sierra Leone. But Guinea, where the outbreak began, has had a more difficult time eradicating the disease.

Dr. Abdourahmane Bathily, head of the Ebola center in Forecariah in western Guinea, said the 68 contacts had emerged from quarantine at midnight on Saturday morning.

"There are no longer any people who had contact with a person infected by the Ebola virus," said Bathily.

He added that the last confirmed Ebola case was a baby in isolation, who should be released from a treatment center next week, allowing for the West African nation to begin its own countdown clock.

. . . Before the outbreak, Sierra Leone was already heavily dependent on aid money. Around 50% of public expenditure programmes were financed by donors, according to UN figures. . . .

. . . Without growth and investment, the country will struggle to create jobs for its young population -- many of whom lack stable employment -- and rebuild public services.

The government's recovery strategy, which is supported by the international community, is about "building back better," says Sudipto Mukerjee, the United Nations Development Program's country director for Sierra Leone. This is particularly relevant to the health sector, which was seriously under-developed before the crisis began, and its weakness undoubtedly contributed to the speed with which the outbreak got out of control.

"When you're talking about the health sector, you're not talking about bringing it back to where you were at the beginning of the outbreak," he says. "That's not good enough. It's also about making sure that you not only build on the investments made so far, but you invest to make it much more resilient in the future."

A new map reveals the path that the Ebola virus took during the outbreak in Sierra Leone, giving a detailed picture of how and where the disease spread, a new study said.

The researchers made the map using a new statistical model, and they say it could be used in the future to improve the way help is delivered to outbreak regions.

"For a future outbreak, this is something that can be readily applied to help identify the regions that need intervention most critically," said study author Jeffrey Shaman, an associate professor of environmental health sciences at Columbia University's Mailman School of Public Health. The model could help authorities figure out where to best deploy people to respond to the outbreak, he said.
