Just when health officials think the Ebola outbreak is over in West Africa, the virus pops up again seemingly out of the blue. It's happened at least five times so far.

It's called a "persistent infection." It's rare. But it has played a big role in keeping Ebola around in Liberia, an international team of scientists report Friday in the journal Science Advances.
