Scientists hope to begin human studies soon.
It could be just a plane ride away. Ebola, the deadly virus that kills many of the people it infects and for which there is no known cure, has hit central African countries, but to date there have been no confirmed cases in North America. On Wednesday, public health officials announced that a woman hospitalized in Hamilton, Ontario, after becoming ill after flying from Congo to Canada was not suffering from Ebola virus, although there was concern Tuesday she might have been. Still, the mere suspicion that someone might be suffering from the Ebola virus is enough to put public health officials on red alert. We live in an age in which the travel time is shorter than the incubation for a disease.
