Chile Begins 3 Days of Mourning for Quake Victims VOA News 07 March 2010 A woman sleeps in front of a makeshift camp set by earthquake survivors in Concepcion, Chile, 05 Mar 2010 Photo: AP A woman sleeps in front of a makeshift camp set by earthquake survivors in Concepcion, Chile, 05 Mar 2010 Flags will be lowered across Chile Sunday, marking the beginning of a three-day period of national mourning for the hundreds of victims of the country's massive earthquake. Officials are still struggling to establish an accurate death toll more than a week after the 8.8-magnitude quake and tsunami shattered central Chile. The Chilean government has changed the official number of people killed by the earthquake from more than 800 to 452. Authorities now say they will add victims to the count only after their remains have been positively identified. The toll was revised after it was discovered that some people who were missing had been listed among the dead. Health officials in Chile have begun a vaccination program to help prevent the spread of disease, administering tetanus and hepatitis vaccine to those at risk in disaster zones. United Nations Secretary-General Ban Ki-moon visited survivors of the quake Saturday. At the site of a toppled apartment building, Mr. Ban said, "We are with you...our hearts are with you." As efforts continue to provide the basics to survivors of the quake, a charity telethon was broadcast to raise money for relief supplies. Some of Latin America's biggest stars performed on the broadcast, which had a goal of raising more than $29 million. Some information for this report was provided by AP, AFP and Reuters. .
