Ebola virus disease (EVD) is a complex zoonosis that is highly virulent in humans. The largest recorded outbreak of EVD is ongoing in West Africa, outside of its previously reported and predicted niche. We assembled location data on all recorded zoonotic transmission to humans and Ebola virus infection in bats and primates (1976–2014). Using species distribution models, these occurrence data were paired with environmental covariates to predict a zoonotic transmission niche covering 22 countries across Central and West Africa. Vegetation, elevation, temperature, evapotranspiration, and suspected reservoir bat distributions define this relationship. At-risk areas are inhabited by 22 million people; however, the rarity of human outbreaks emphasises the very low probability of transmission to humans. Increasing population sizes and international connectivity by air since the first detection of EVD in 1976 suggest that the dynamics of human-to-human secondary transmission in contemporary outbreaks will be very different to those of the past.

The unpredictable Ebola outbreak in West Africa is thwarting health officials' best efforts both to contain the epidemic, as well as test new treatments and vaccines.

The number of new Ebola cases has risen sharply in the West African nation of Guinea, for example, even as researchers wonder if there will be enough patients in neighboring Liberia to test experimental vaccines.

Just a few weeks ago, the number of new Ebola cases was falling in all three West African countries....

 In October, scientists set out to do something unprecedented – conduct a drugs trial during an epidemic to find a treatment for a lethal disease. Could they make history and change the way we deal with outbreaks?

In depth description of efforts by a group of Oxford University scientists to run field trials of drugs for use against Ebola.

" ...The little band of scientists had flown to Guinea on 16 October to do something that had never been successfully done before – set up a trial of experimental drugs against an infectious disease in the middle of an epidemic. Because the Ebola virus does not exist at low levels in any population, unless you run a properly conducted trial while the storm is raging, you will never have drugs that are proven to be effective. The Oxford team’s trial would not only aim to find a drug that worked against Ebola but also to establish a blueprint for the way drug trials would be run during outbreaks in the future. This did not just apply to fighting Ebola: if the scientists were successful, their trial would develop protocols for testing drugs for any epidemic, be it Sars or flu...."

Conakry, Guinea --Statement issued by the heads of Guinea, Liberia and Sierra Leone upon approving an operational framework designed to reduce new Ebola infections to zero within 60 days.

The framework calls for infection prevention and control, social mobilization, community engagement, surveillance, cross border collaboration. 

The leaders also "advocated for a seamless and responsible exit by international partners dictated by the epidemiology and by the adequate transfer of capacity to national institutions."

The statement includes a list of developments and responses.
