Bodies were piled into mass graves in the belief that burial would ward off disease. And, as CBS News Correspondent Allen Pizzey reports, many of the bodies will never be identified.
"The bodies are in very, very bad shape," Jerome Folee, a Swiss man searching for his family told Pizzey. "Apart from very factual things like clothes or earrings … it's, I would say, impossible to identify."
Paramedics in southern India began vaccinating thousands of survivors against cholera, typhoid, hepatitis A and dysentery, and authorities sprayed bleaching powder on beaches where bodies have been recovered. In Sri Lanka,.

"We're facing a disaster of unprecedented proportion in nature," said Simon Missiri, a top Red Cross official. "We're talking about a staggering death toll."
On hundreds of Web sites, the messages were brief but poignant: "Missing: Christina Blomee in Khao Lak," or simply, "Where are you?" All conveyed the aching desperation of people the world over whose friends and family went off in search of holiday-season sun and sand and haven't been heard from for four days.
But even as hope for the missing dwindled, survivors continued to turn up Wednesday. In
Indian air force planes evacuated thousands of survivors from the remote island of Car Nicobar. Some of them had walked for days from their destroyed villages to reach a devastated but functioning airfield, where they were shuttled out 80 to 90 at a time.
India's death toll rose to nearly 7,000, while Indonesia's stood at 45,268, but authorities said this did not include a full count from Sumatra's west coast, where more than 10,000 deaths were suspected in one town alone.
In Sumatra, the Florida-sized Indonesian island close to the epicenter of the quake, the view from the air was of whole villages ripped apart, covered in mud and seawater. In one of the few signs of life, a handful of desperate people scavenged a beach for food. On the streets of Banda Aceh, the main town of Sumatra's Aceh province, the military managed to drop supplies from vehicles and fights broke out over packs of instant noodles.
Thailand said it had more than 1,800 dead and a total of more than 300 were killed in Malaysia, Myanmar, Bangladesh, the Maldives, Somalia, Tanzania and Kenya.
Outside of the resort town of Khao Lak, Thailand, CBS News Correspondent Barry Petersen witnessed both science and religion taking roles in the mourning. As scientists took DNA samples of the dead prior to burial, family of the dead mourned their relatives in a makeshift mortuary — the Yang Yaow Buddhist Temple.
Widespread looting was reported other devastated resort islands in Thailand, such as Phuket and Phi Phi, where European and Australian tourists left valuables behind in wrecked hotels when they fled — or were swept away.
Maj. Gen. Endang Suwarya, military commander of Aceh province, said after flying over the stricken region that 75 percent of the west coast of Sumatra was destroyed.
Footage shot by an Associated Press Television News cameraman on the military helicopter showed town after town covered in mud and sea water. Homes had their roofs ripped off or were flattened.
A solitary mosque and green treetops were all that broke the line of water in one town.
With tens of thousands of people still missing across the entire region, Peter Ress, Red Cross operations support chief, said the death toll could top 100,000. More than 500,000 were reported injured.
"We have little hope, except for individual miracles," Jean-Marc Espalioux, chairman of the Accor hotel group, said of the search for thousands of tourists and locals missing from beach resorts of southern Thailand — including 2,000 Scandinavians.
The— seven in Sri Lanka and five in Thailand. About 2,000 to 3,000 Americans were unaccounted for.
Bush, at his ranch in Crawford, Texas, talked by phone Wednesday with leaders of Indonesia, Sri Lanka, Thailand and India.
"We're still in the stage of immediate help. But slowly but surely, the size of the problem will become known, particularly when it comes to rebuilding infrastructure and community to help these affected parts of the world get back up on their feet," Bush said afterward.
The Pentagon says it will divert several U.S. warships and helicopters to the region, some of which can produce up to 90,000 gallons of drinking water a day. Mr. Bush has also said the United States' contribution to relief efforts will be multifaceted, and extend far beyond the.
Without clean water, respiratory and waterborne diseases could break out within days, putting millions at "grave risk," the U.N. children's agency said. "Standing water can be just as deadly as moving water," said UNICEF Executive Director Carol Bellamy. "The floods have contaminated the water systems, leaving people with little choice but to use unclean surface water."
Near Banda Aceh, trucks dumped more than 1,000 bloated, unidentified bodies into pits. Military Col. Achmad Yani Basuki said there was no choice, given the danger of disease and the difficulty of identifying any of the dead.
But Dana Van Alphan of the Pan American Health Organization issued a statement declaring there was no danger of corpses contaminating water or soil because bacteria and viruses cannot survive in dead bodies. The organization said it issued the statement, hoping to avert mass burials of tens of thousands of unidentified victims.
Van Alphan said it was important for survivors to be allowed to identify loved ones and urged authorities in tsunami-stricken countries to avoid burying unidentified corpses in mass graves.
"I think that psychologically, people have to be given the chance to identify their family members," she said. "Whatever disease the person has while still alive poses no threat to public health in a corpse."
Relief efforts were underway Wednesday, as individuals around the worldand nations sent supplies in. In Sri Lanka, four planes arrived in the capital bringing a mobile hospital from Finland, a water purification plant from Germany, doctors and medicine from Japan and aid workers from Britain, the Red Cross said.
Supplies that included 175 tons of rice and 100 doctors reached Banda Aceh but officials said they were having difficulty moving it out.
An international airlift was under way to ferry critical aid and medicine to Phuket and to take home travelers, some with nothing but the clothes they were wearing. France, Australia, Greece, Italy, Germany and Sweden were sending flights.
The world's biggest reinsurer, Germany's Munich Re, estimated the damage to buildings and foundations in the affected regions would be at least $13.6 billion.
