While relief in the form of food, water and basic medical supplies continues to make its way into Haiti's devastated neighborhoods, many victims are still fighting their way out of the capital city into outlying towns or the Dominican Republic.
For some, the exodus is their only way to get help as tens of thousands of injured Haitians still await medical treatment. One hospital reported that 1,000 patients were waiting for surgery.
At the Albert Schweitzer Hospital in Deschapelles, three hours outside the earthquake zone, the scene was stunning.
Victims with untreated broken bones, gaping wounds and severe head injuries lined every bit of the hospital halls. There were more than 500 patients and 80 beds.
A nurse told ABC News the victims were bused in, broken bones and all.
Doctors aboard the USNS Comfort, a 900-foot floating hospital nearing Haiti, have also begun treating their first patients, according to The Associated Press.
Dr. Jon Crocker of Partners in Health posted on the organization's Web site that people who have been lucky enough to survive their injuires so far are now succumbing to ailments such as massive infection and blood clots.
Ian Rawson, head of the Albert Schweitzer Hospital, told ABC News' senior health and medical editor Dr. Richard Besser that many of the hospital's employees who had previously been laid off came back after the earthquake to help save their family members.
It's the "biggest demand on this hospital I have ever seen," he said, crying.
It's a demand they don't seem to be able to meet. The hospital is running out of supplies and signs of that shortage are everywhere. They're out of crutches and running dangerously low on antibiotics. The only pain medication left is a small amount of Motrin.
"I wish we could get some medicine, some pain medicine and antibiotics," Rawson said. "These people are enduring horrible pain."
Dr. Emmanuel Fransoise, an orthopedic surgeon, hasn't left the hospital since Sunday night. He has already performed more than 20 surgeries and had dozens yet to go. He said he's not willing to give up.
"We are Haitian, we have hope," he said, adding that hope comes "from the inside."
