The numbers are staggering: 1,552 people are dead, and more than 1 million quarantined with limited access to food and medical supplies. But even more shocking are the scenes from inside the hot zone, where hopes are low and fears are high.
ABC News' chief health and medical editor Dr. Richard Besser traveled to Monrovia, Liberia, a city at the centers of the outbreak. He visited a slum cut off by the quarantine barrier, where terrified residents are desperate to share their stories.
He met a survivor, who is determined to return to his job as an emergency medicine doctor despite the infection risk.
And he toured an Ebola ward, where patients wait on dirt floors to survive or die.
Before leaving Liberia, Dr. Besser had to go through special airport screening procedures aimed at limiting the virus's spread.
