At the time of Wednesday’s announc

ement out of Guinea that seven of nine missing Ebola workers had been found dead, we knew little. Men with knives had abducted members of a group sent there to spread awareness about the disease. Two relief workers were missing; the rest, dead. Six suspects were in custody.

By Friday morning, we knew more. These details, the stuff of horror films. A local government group of relief workers—a mix of doctors, religious leaders, and journalists—had arrived Monday to educate the remote southeastern village of Womey about Ebola. Just 24 hours after their arrival, violence broke out, allegedly sparked by the false belief that a disinfectant being sprayed was actually the disease itself. An angry mob brandishing machetes, stones, and knives lashed out.

The World Health Organization has declared the Ebola outbreak in West Africa to be an international public health emergency that requires an extraordinary response to stop its spread.

It is the largest and longest outbreak ever recorded of Ebola, which has a death rate of about 50 per cent and has so far killed at least 932 people.

"Countries affected to date simply do not have the capacity to manage an outbreak of this size and complexity on their own," WHO chief, Dr. Margaret Chan, said at a news conference in Geneva. "I urge the international community to provide this support on the most urgent basis possible."

In the United States, the Centers for Disease Control and Prevention have already elevated their Ebola response to the highest level and have recommended against travelling to West Africa. On Thursday, CDC director Dr. Tom Frieden told a Congressional hearing that the current outbreak is set to sicken more people than all previous outbreaks of the disease combined.

The World Health Organization is launching a $100 million response plan to combat an "unprecedented" outbreak of Ebola in West Africa that has killed 729 people out of 1,323 infected since February.
