The record-breaking floods that hit Pakistan three weeks ago have caused enormous damage to the country. More than 1,400 people have been killed and over 20 million affected. One fifth of the country's land has been submerged. But as waters begin to recede, Pakistanis could be faced with yet another problem.
Roads and bridges have been swept away, farms and fields inundated, and crops destroyed.
But as waters gradually recede, the scale of the disaster is slowly being revealed as survivors remain at risk of diseases.
Aid agencies are predicting possible epidemics in affected areas, since many victims are still living in makeshift camps and do not have access to clean water.
Mohammad Salman, Punjab Province, said, "The mosquitoes are all over the place. They don't let us sleep and they will spread diseases. Children are suffering from diarrhea and fever. "
Salman's wife, said, "Our children are sick. The water from the hand pump is dirty, but we all drink this water, which may cause many diseases. "
So far there have been 36,000 suspected cases of acute diarrhea reported.
The United Nations has warned that up to 3 and a half million children could be in danger of contracting deadly diseases carried through contaminated water and insects.
To combat this, the United Nations will provide clean water to six million people in flood-ravaged areas.
Last week, the United Nations appealed for 460 million US dollars for Pakistan's relief work. 40 percent of that is now in place.
The World Bank has also pledged to redirect 900 million US dollars to help Pakistan's rebuilding efforts.
