# The flooding in Pakistan is still posing major challenges to millions of people across the nation. In the north, the high waters are receding at a very slow pace, isolating many and threatening the spread of disease. In the far south of the country, it could take even longer, with water levels still on the rise. Besides malnutrition, aid agencies are also concerned that if the reconstruction effort doesn't begin immediately, the disaster could become a long-term catastrophe.
