Jong-wook Lee, head of the World Health Organization has arrived in northwestern Pakistan to inspect the damage caused by the massive earthquake two months ago.
Lee is here to check on preparations being made for the onset of the harsh Himalayan winter.
His agency says its main immediate task is to immunize as many people as it can to try to ward off epidemics. Some 400,000 children have already been immunized against measles. It's also distributed 20-thousand tents, 60-thousand plastic sheets and 322-thousand blankets.
'WHO will continue to help Pakistan and assist aid agencies to provide medical treatment to the survivors,' Lee told reporters. 'Luckily there has not been any outbreak of diseases, mainly because the plans were implemented swiftly.'
Pakistani officials say the earthquake destroyed 50 percent of the health system in northwest Pakistan and Azad Jammu and Kashmir. WHO has helped immunize 400,000 children in the area against measles. During his tour, Lee was set to visit a field hospital and meet with senior government officials.
The quake killed some 87-thousand people and left millions homeless.
