Experts worry a health crisis could be looming nearly two weeks after massive flooding engulfed much of Kashmir, with countless bloated livestock carcasses now floating across the waterlogged region.

Doctors are already seeing cases of diarrhea, skin allergies and fungus among the population. Rescue workers are rushing in medical aid, water pumps and purification systems.

Dr. Swati Jha with the aid group Americares said Tuesday that "the most essential need right now is that of clean water."

The scale of the disaster is unprecedented for the Himalayan region, which is divided between India and Pakistan while being claimed by both.

In Indian Kashmir, more than 200 people have been killed and another 275,000 evacuated since the floods hit 13 days ago.
