(CNN) -- The death toll from flooding in the Philippines has climbed to 47, the country's national disaster agency said Sunday.
Parts of the Philippines have been dealing with the effects of heavy rainfall for weeks. A monsoon triggered rains, flooding and landslides affecting 25 provinces, the National Disaster Risk Reduction and Management Council said in a statement.
More than 1.5 million people have been affected, the disaster agency said. Among 10 impacted regions, Caraga -- on the eastern island of Mindanao -- has the greatest number of people affected at more than 600,000.
Many of the 47 fatalities -- ranging from ages 1 to 80 -- died from drowning, landslides or electrocution, according to the disaster agency. At least four people remained missing Sunday.
In addition, 503 homes have been destroyed, and 1,914 have been damaged, the agency said.
An aircraft carrying a medical team and emergency medical supplies was scheduled to land in Siruma, Camarines Sur, on Sunday "to address the life-threatening condition" of about 450 households affected by diarrhea, the disaster agency said. CNN
