Some 300 people are feared dead after days of heavy rain caused rivers to break their banks last week, flooding parts of the country's north east, as well as neighbouring Bhutan, Nepal and Bangladesh. Swollen rivers receded on Saturday, allowing teams of doctors to take food and medicine to thousands of victims and allowing people to revisit their homes. In the next couple of days more relief material will reach us and we will start massive operations from 16 August. But worse could be on the way, with more heavy rain and thunderstorms predicted over the next 24 hours. Skin diseases and dysentery are now commonplace and the first cases of malaria are being seen.
Doctors say with thousands of people in temporary shelters, there is a growing threat of cholera.
Our correspondent Jill McGivering says in the worst-affected areas there is little left of either houses or crops. People are salvaging what they can but returning to emergency shelters at night because their homes are not inhabitable. The surroundings will be polluted and the water source filled with filth and mud, and hence the worry. Crops destroyed There will be longer term problems as well. The whole infrastructure needs to be rebuilt - bridges, roads and flood defences have been swept away.
