The death toll from the south Asian earthquake has now reached 53,000 in Pakistan, with 40,000 dead in Pakistani-administered Kashmir alone.
Another 3.3 million have been left homeless and officials and aid agencies are warning that many will not receive help before winter closes in on the rugged Himalayan region.
The earthquake also ravaged the Indian side of divided Kashmir, killing 1,329 people there, according to Indian police.
More than a week after the earthquake, much of the relief aid is still only trickling in to the worst-hit areas.
The World Health Organisation has said that as well as the risk of infectious disease among survivors, there is a grave risk of hypothermia as winter snows begin settling on mountain peaks.
The prime minister of Pakistani-administered Kashmir has called for the opening of the border with Indian Kashmir, to help relief operations on both sides of the line of control.
Sardar Sikandar Hayat Khan said the Pakistani government should set aside any reservations it had about such a move.
Earlier, a young girl suffering from polio was rescued from rubble in Pakistan, eight days after the earthquake struck south Asia.
Two older brothers managed to raise the alarm after walking from their village near the town of Balakot.
An army spokesman said their village had been destroyed in the earthquake.
Meanwhile, a Pakistan army helicopter has crashed in Kashmir during a relief operation for the earthquake-shattered region.
Six soldiers were killed in the crash.
Officials say the MI-17 helicopter crashed while returning to Islamabad after dropping relief supplies.
