Sanitary condition of fishing hamlets

Tens of hundreds of crores flowed in through governments and NGOs around the world, after tsunami,but nothing notable has been done to improve the sanitary condition of the fishing villages. Fisheries still stick on to age old way of doing things, irrespective of their economic background. They may be preoccupied, still isn't it the responsibility of the government to build toilets for the commuinity and educate them to use it properly.
