"We don't have any antibiotics," Besser said. "What I would like to do is change his dressing, clean his wound, put on new medicine and pack it. But that's something we don't have."
A 3-month-old infant in the camp was not injured in the earthquake, but also faced potential death. The mother was feeding the baby sugar water because formula wasn't available, but babies fed sugar water can die of malnutrition.
Despite the shortages at the camp, at least 180 tons of relief has landed in Haiti, U.S. officials said this morning. The government of Haiti has established 14 distribution points for aid, and five medical centers were up and running.
ABC News was able to ride along as aid workers from the World Food Program hoped to deliver 40,000 rations of high-energy biscuits, water tablets and pre-packaged meals. In the end, though aid got delivered, obstacles prevented the workers from even approaching their goal for the day.
For one thing, the scope of the disaster was so large that the aid group had to step up the delivery and include secretaries and other workers who did not normally load relief vehicles. Everyone from the office pitched in.
Soon, the strong aftershock caused volunteers to flee an already earthquake-damaged warehouse. Many refused to go back in for fear it would collapse.
After several hours the truck was loaded and finally on the way. A convoy was formed. U.N. security forces, including armored personnel carriers, accompanied the convoy through the streets to stave off the possibility of violence or a rush on the supplies.
The trucks rattled through Port-au-Prince, passing masses of people without shelter and food.
Four hours into the mission, they hit a roadblock of bodies. People began massing around the vehicles, desperate for supplies, saying, "We are hungry, we have nothing."
The truck found another way and at last, five and half hours after the trip began, the food was finally delivered at a local church, where mothers and children had been waiting all day, streaming in from a massive tent city nearby.
When the boxes were finally handed out, there seemed to be nothing but gratitude.
But even as aid started to move early today, the shock and grief in the aftermath of the earthquake already was turning to panic for many. In one shantytown, a water truck pulled up and people flocked to the back of the truck to get water for themselves and those in need.
"They are dying because nobody comes to help us," one man said.
"All of my family is dead," said another. "My mother is dead, my father is dead, my house is crushed; I have nothing."
The smell of decay has grown so strong from bodies littered through the streets and baking in the sun that people are putting toothpaste under their nostrils to help block the stench of death.
"We see the helicopters, and they do nothing," one Haitian complained.
"They're hungry," another man said of his fellow Haitians. "They don't have food. They don't have water. They don't have nothing."
Officials insist more help is coming.
Callaghan said U.S. rescue teams will be working "nonstop." He declined to say when that effort will transition to a recovery operation.
Callaghan defined water as a top priority. The United States brought in water purification units Friday night and is donating one to the medical center being run by Argentina.
