Ebola Outbreak

Nearly 40 years after first striking fear with a painful, grotesque set of symptoms, the Ebola virus has now killed at least 88 people in the West African countries of Guinea and Liberia. And the worry is: It could get a lot worse. It is a terrifying virus, highly infectious, quick to kill, with no vaccine and no cure.

Doctors in Guinea are dealing with the most aggressive strain. Only one out of ten victims survives. To stop Ebola everyone who has come into contact with the virus must be isolated

Michel Van Herp, an epidemiologist for the aid group, Doctors Without Borders, said that they were facing an epidemic on an unprecedented scale -- not in numbers of victims, but because the cases are so spread out in Guinea and across its borders. The only way to stop Ebola is to find and isolate everyone who has come into contact with it.
