Smart guys at Oxford predict an additional 15 Countries are at risk:
Until this year's epidemic, Ebola did not exist in West Africa. Now with more than 1,800 people dead from the virus, mostly in Liberia, Guinea and Sierra Leone, scientists still don't fully understand how Ebola arrived from Central Africa, where outbreaks of this strain of the virus had occurred in the past.
A new model by Oxford University, that is published in the journal eLife, takes a look at the most likely explanation -- that Ebola's animal reservoir, fruit bats, could spread the disease in the animal kingdom and to humans through the dense forest that spans 22 countries.

According to the Oxford model, in addition to the seven countries who have reported Ebola outbreaks in this epidemic and in past outbreaks since the disease was identified 1976, 15 other countries are at risk. There are five known strains of Ebola, and the one currently causing the West African outbreak, Zaire, is the most virulent. The other strains, Sudan, Taï Forest and Bundibugyo, have caused contained outbreaks in Ivory Coast, Sudan, and Uganda in the past. And the Reston species has not caused any known outbreaks, according to the World Health Organization.
According to the Oxford prediction, these countries are at risk of animal-to-human transmission of Ebola by virtue of their geography: Nigeria, Cameroon, Central African Republic, Ghana, Liberia, Sierra Leone, Angola, Togo, United Republic of Tanzania, Ethiopia, Mozambique, Burundi, Equatorial Guinea, Madagascar and Malawi.
"Our map shows the likely ‘reservoir’ of Ebola virus in animal populations, and this is larger than has been previously appreciated," said the study's author Nick Golding, a researcher at Oxford University’s Department of Zoology. "This does not mean that transmission to humans is inevitable in these areas; only that all the environmental and epidemiological conditions suitable for an outbreak occur there.’"
In related news, Ebola is spreading "exponentially" across Liberia:
The Ebola virus is spreading exponentially across Liberia as patients fill taxis in a fruitless search for medical care, the World Health Organization said Monday.
In Sierra Leone, a doctor working for WHO tested positive and was preparing to be evacuated from the country. Meanwhile, the newest U.S. patient, a doctor infected in Liberia, was feeling a little better and could even eat a little, doctors treating him in Nebraska said.
The various reports illustrated in the clearest possible way the disparities driving the epidemic in West Africa, where there’s almost no medical system structure. The three patients evacuated to the United States have all begun to recover quickly once they get good supportive care, which includes around-the-clock nursing care and good nutrition.
“In Monrovia, taxis filled with entire families, of whom some members are thought to be infected with the Ebola virus, crisscross the city, searching for a treatment bed. There are none. As WHO staff in Liberia confirm, no free beds for Ebola treatment exist anywhere in the country.”
For example, in Montserrado county, 1,000 beds are urgently needed but only 240 beds are available. WHO has said more than 3,600 people have been infected with Ebola in this West African epidemic, and 2,000 have died, but the organization predicts as many as 20,000 will be sickened before it’s over. Half of those infected have been dying.
“According to a WHO staff member who has been in Liberia for the past several weeks, motorbike-taxis and regular taxis are a hot source of potential Ebola virus transmission, as these vehicles are not disinfected at all, much less before new passengers are taken on board,” WHO said.
“When patients are turned away at Ebola treatment centers, they have no choice but to return to their communities and homes, where they inevitably infect others, perpetuating constantly higher flare-ups in the number of cases.”
