One of the success stories, according to ABC News senior health and medical editor Dr. Richard Besser, has been the Israeli aid effort. On "World News with Diane Sawyer," he pointed out that after arriving in Haiti on Friday night, they had a field hospital up and running on Saturday morning.
The field hospital, which Besser said was impressively orderly, has tents that specialize in different areas, including intensive care units and surgeries.
"It has military precision," Besser said. "You see a pediatric ward, you see a maternity ward, a newborn intensive care unit."
Besides security, Conti is worried about the spread of disease.
"We must rapidly address these water and sanitation issues if we want to minimize the risk of an outbreak of disease," said Conti. "This is really paramount."
Fingerpointing has erupted among the countries rushing to Haiti's aid.
Benoit Leduc, operations manager for Doctors Without Borders in Haiti, said they are 48 hours behind on operations because five of their planes have not been able to land at the airport, which has become a choke point for supplies.
"I don't really know who is in charge. We are doing our best just to treat the people that are just in front of our gates," Leduc said.
A French official sniped at the United States today after a French plane carrying a field hospital was turned away from the overcrowded airfield which is now being run by air traffic controllers from the U.S. Air Force. The plane was later allowed to land.
French Cooperation Minister Alain Joyandet said he wants the United Nations to clarify the U.S. role in Haiti's emergency.
"This is about helping Haiti, not about occupying Haiti," Joyandet said.
Despite the confusion and chaos, 40 international search-and-rescue teams including nearly 1,800 rescue workers and more than 160 dogs are frantically combing through the rubble looking for the hardy or lucky one who have survived seven days entombed in cement.
American search and rescue teams from Florida, New York, Virginia and California have pulled 35 people from the wreckage of Haiti's earthquake, including 10 on Sunday which the Haiti Joint Information Center said is "the largest number of rescues in a single day in decades of earthquake search."
"Everybody gets pretty amped up when they have a live person in there," USAID rescuer Joe Kaleda told "Good Morning America" today. "We want to get them out of there as quick as we can."
