Flash floods triggered by torrential monsoon rains have so far killed as many as 15 hundred people, and left 2 million others homeless in Pakistan.
Thirty-thousand houses have been destroyed. About 30 thousand troops have been deployed for the relief effort across the country. To add to the misery, people in the affected areas are facing the threat of waterborne disease.
Thousands more could die if health workers cannot deliver enough clean drinking water, and treat and isolate any patients in crowded relief camps.
A local official says there have been some cases of diarrhea and people experiencing asthma in relief camps.
