"We're a little bit frustrated," Rawson said. "There are stacks of medical supplies in Port-au-Prince, but we haven't been able to work through the log jams to find out where they are."
Rawson added that he expects a second wave of patients at his hospital in the days to come as the decimated facilities in Port-au-Prince become overwhelmed.
"Now, we have people in the hospitals in Port-au-Prince who don't have any resources," he said. "They are e-mailing us and saying, 'Can we send patients?'"
For Kennedy and her team, supplies are a lesser concern; charter flights bearing medical supplies have resulted in a steady stream of medical and humanitarian necessities from the airport, and she expects another shipment Sunday.
But as the specters of exposure, malnutrition and disease loom, her organization's relief workers are using what they can -- from blankets to water purification efforts -- to keep the earthquake's victims as healthy as possible.
"We are heading into the rainy season, and always during the rainy season these diseases go up," Kennedy said. So without adequate shelter in place, these diseases could really go up."
