The international Red Cross warned that the toll could eventually surpass 100,000. The race was on to try to prevent an outbreak of diseases and to curb food shortages among millions of homeless — which the U.N. health agency said could kill as many as the waves and quake.
Sri Lanka said it was getting its first reports of measles and diarrhea. Paramedics in southern India began vaccinating 65,000 survivors against cholera, typhoid, hepatitis A and dysentery, and authorities sprayed bleaching powder on beaches where bodies have been recovered.
``Even those people who (didn't lose homes) can't get food. Nothing is available,'' said Father Raja Perera, of St. Mary's Roman Catholic church in Sri Lanka's second largest city, the hard-hit southern resort of Galle, where refugees from ravaged homes crowded into churches, Buddhist temples and mosques.
Town after town along Indonesia's Sumatran coast was covered with mud and sea water, with homes flattened or torn apart, an Associated Press reporter saw on a helicopter overflight with the military commander of the island's Aceh province. The only signs of life were a handful of villagers scavenging for food on the beach.
Western Sumatra suffered a double blow in Sunday's disaster, shattered both by the most powerful earthquake in 40 years and perhaps the deadliest tsunami in recorded history, which wreaked destruction across a dozen nations.
``The damage is truly devastating,'' Maj. Gen. Endang Suwarya said.
``Seventy-five percent of the west coast is destroyed and some places it's 100 percent. These people are isolated and we will try and get them help.''
The first military teams reached the devastated fishing town of Meulaboh on Sumatra's coast and across the coast they found thousands of bodies, bringing Indonesia's toll to 45,268, according to the Health Ministry's official count. That toll was likely to rise — one official on Tuesday estimated that as many as 10,000 people were dead in Meulaboh alone.
Sri Lanka on Wednesday listed more than 22,400 people dead, India close to 7,000 — with 8,000 missing and feared dead. Thailand put its toll at more than 1,800. Another 340 were killed in Malaysia, Myanmar, Bangladesh, the Maldives, Somalia, Tanzania and Kenya.
From East Africa to southern Asia, chances faded of finding more survivors of Sunday's massive, quake-driven walls of water. Tens of thousands of people were still missing. German Chancellor Gerhardt Schroeder said 1,000 Germans were unaccounted for.
``We have to fear that a number of Germans clearly in the three-digit numbers will be among the dead,'' Schroeder told reporters. Currently, 26 Germans have been confirmed dead.
``We have little hope, except for individual miracles,'' Chairman Jean-Marc Espalioux of the Accor hotel group said of the search for thousands of tourists and locals missing from beach resorts of southern Thailand — including more than 2,000 Scandinavians.
In Sri Lanka, reports of measles and diarrhea were beginning to reach health authorities, causing concern of an epidemic, said Thilak Ranaviraj, the government's top official handling relief efforts.
In a field in Banda Aceh, the capital of Sumatra's Aceh province, bulldozers shoved more than 1,000 unidentified bodies into mass graves. The corpses had been picked off the city's streets as authorities rushed to get decaying bodies into the ground.
``What worries us is the lack drinking water,'' said Dr. Georg Petersen, the World Health Organization representative in Indonesia. ``That means that people might drink contaminated water and they can get sick from waterborne diseases like diarrhea.''
Four relief planes arrived in Sri Lanka's capital, Colombo, bringing a surgical hospital from Finland, a water purification plant from Germany, doctors and medicine from Japan and aid workers from Britain, the Red Cross said.
Meanwhile, trucks fanned out across the island nation to deliver bandages, antibiotics, tents, blankets and other supplies to the hardest hit areas, the southern and eastern coast. A dozen trucks left the U.N. World Food Program depot in Colombo on Tuesday. The military said a fleet of 64 trucks packed with rice, sugar, tents and other essentials entered Tamil areas Wednesday.
But officials in the east said at least four WFP trucks bound for Tamil areas in the north were forcefully diverted by Sinhalese mobs and low-ranking government officials to predominantly Sinhalese areas. Selvi Sachchithanandam, a WFP spokeswoman, declined to comment on the report.
Sri Lanka has been torn for years by a conflict with separatist Tamil rebels who control parts of the north, demanding independence from the mostly-Sinhalese nation.
Indonesia's military said a navy flotilla was headed to Sumatra's western coast to being him. Supplies — including 175 tons of rice and 100 doctors — reached Banda Aceh, but with aid not arriving quickly enough, desperate people in towns across Sumatra stole whatever food they could find, officials said.
Widespread looting also was reported in Thailand's devastated resort islands of Phuket and Phi Phi, where European and Australian tourists left valuables behind in wrecked hotels when they fled — or were swept away by — the torrents.
An international airlift was under way to ferry critical aid and medicine to Phuket and to take home shellshocked travelers. Jets from France and Australia were among the first to touch down at the island's airport. Greece, Italy, Germany and Sweden planned similar 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.
Donations for recovery efforts came in from all parts of the globe.
The governments of the United States, Australia and Japan pledged a combined $100 million while taxi drivers in Singapore put donation tins in their cars and volunteers in Thailand text-messaged aquaintances to give blood to the Red Cross
