Flood waters have started to recede in Pakistan after the worst flooding in country's history.
The high waters have resulted in the death toll being estimated near 1,200. But that number could rise this week.
Residents have expressed anger with the Pakistani government, saying it failed to provide enough emergency help nearly a week after the heavy monsoon rains caused floodwaters to rise in the Khyber-Pakhtoonkhwa province.
"We need tents. Just look around," said flood victim Faisal Islam, sitting on the only dry ground he could find in Nowshera district - a highway median.
"This is the only shirt I have," Islam said. "Everything else is buried."
Soldiers and rescue workers are still trying to rescue people who are still trapped by high water. Pakistan deployed 30,000 troops, who have helped rescue more than 28,000 people.
But the threat of waterborne disease in the northwest part of the Islamic country could kill thousands of people if health workers cannot deliver enough clean drinking water and treat and isolate any patients in what are expected to be crowded relief camps.
"To avert the looming threat of spread of waterborne diseases, especially cholera, we have dispatched dozens of mobile medical teams in the affected districts," said Sohail Altaf, the top medical official in Khyber-Pakhtoonkhwa.
The U.S. has provided rescue boats, water filtration units, prefabricated steel bridges and thousands of packaged meals.
