(CNN) -- The massive flooding that has covered about one-fifth of Pakistan has claimed the lives of more than 1,500 people, authorities said Saturday.
The death toll from the three-week flooding has reached 1,514, the nation's disaster management agency said.
Officials fear the number could continue to rise because of diseases from unsanitary conditions.
More than 200 health facilities have been damaged or destroyed, according to the World Health Organization, greatly reducing the available health care for millions of survivors in filthy conditions. At least 4 million people are homeless.
Dr. Guido Sabatinelli of the World Health Organization said reports of diarrhea have increased 30 percent. CNN
