Over the past few decades, we've suffered at the hands of more than a few viruses. It's perhaps the most frightening, and most frustrating killer of them all - a killer without a face, or body, or anything that we can place blame on. We just suffer slowly while the news outlets get bored, and hope that one day a cure can be found.
The recent Ebola outbreak - which is still on-going, in case you didn't know - was just the latest in a series of appearances by the deadly infectious disease. No moment of it, though, has been captured quite so eloquently as this photo, of nurse Mayinga N'Seka. She was at the battlefront when the very first outbreak of Ebola occurred 1976, and the haunted look in her eyes tells an all-too-clear story. Two days later, she died.
