The death toll caused by Super Typhoon Yolanda (Haiyan) has climbed to 1,774 as of 6 p.m. Monday, the National Disaster Risk Reduction and Management Council (NDRRMC) reported.
Military spokesman Lieutenant Jim Alagao said 275 others were confirmed missing from the storm.
The death toll is expected to rise considerably as two provincial officials predicted Sunday that it could reach 10,000 or more.
Disrupted transportation and communication links make it difficult to count the dead and distribute relief goods.
Yolanda raced across the eastern and central Philippines, inflicting serious damage to at least six of the archipelago's more than 7,000 islands, with Leyte, neighboring Samar Island, and the northern part of Cebu appearing to take the hardest hit. It weakened as it crossed the South China Sea before approaching northern Vietnam.
Corpses hung from tree branches and were scattered along sidewalks and among flattened buildings, while looters raided grocery stores and gas stations in search of food, fuel and water.
Department of Public Works and Highways (DPWH) teams from other regions were already sent to the Eastern Visayas to assist in the clearing operations of national roads and bridges.
President Benigno Aquino III declared Monday night state of national calamity, following the recommendation of the National Disaster Risk Reduction and Management Council.
"Idinedeklara po natin ang state of national calamity upang mapabilis ang mga pagkilos ng pamahalaan para sa pagsagip, paghahatid ng tulong, at rehabilitasyon ng mga probinsyang sinalanta ni Yolanda," Aquino said in a televised message from Malacanang.
The President said that the government has still available funds of P18.7 billion, which can be used for the rehabilitation of areas devastated by the typhoon.
Philippines is yet to recover from the devastation of Yolanda. However, another tropical depression, named as "Zoraida," entered the country early Monday. At least 21 areas are under Public Storm Warning Signal Number 1.
