Her eyes met the camera. She was there. And yet she wasn't there.
That's how NPR photographer David Gilkey remembers the moment last Saturday when he took a picture of Baby Sesay, a 45-year-old traditional healer in the village of Royail in Sierra Leone.
Sesay had tried to cure a sick little boy. The boy died, likely of Ebola. Then Sesay herself fell ill. She had come to a community care center a few hours earlier, walking in under her own power, to be tested for the virus.
