New Killer African Virus

A new killer virus has been discovered in Africa.

ATLANTA - Scientists have identified a lethal new virus in Africa that causes bleeding like the dreaded Ebola virus.

The so-called "Lujo" virus infected five people in Zambia and South Africa last fall. Four of them died, but a fifth survived, perhaps helped by a medicine recommended by the scientists.

It's not clear how the first person became infected, but the bug comes from a family of viruses found in rodents, said Dr. Ian Lipkin, a Columbia University epidemiologist involved in the discovery.
