Worst Ebola Outbreak in Seven Years Kills 83 in Guinea

The death toll from the worst Ebola outbreak in seven years climbed to 83 in Guinea as the aid organization Doctors Without Borders said the disease’s geographical spread marks the flare-up as unprecedented.

In neighboring Liberia, one of two confirmed cases has died, while a second person who died with a suspected Ebola infection tested negative for the virus, the World Health Organization said in a statement. Both confirmed cases in Liberia were exposed to Ebola in Guinea, Gregory Hartl, a WHO spokesman, said on Twitter.
