Background: A boat town has risen along the banks of river Ichhamati near Tetulia town. Over two thousand boats carrying refugees had sailed away form Khulna during the early influx of Refugees from East Pakistan into India. Nearly a thousand of these are now berthed along the banks at Tetulia. Families, mostly fiser folk, live on boats here. Some of them come to the river bank for cooking, but mostly it is down on the boats. Refugees in the boat town are eagerly waiting to return to their homes. As a monsoon down pour hit the area, the refugees tucked under the cover on boats. Here doctors move by boats to keep a check on the health of the boat inhabitants. Mostly cases of cold, pneumonia and bronchial disease have been detected. The boat town has a so far escaped the horror of Cholera which hit several camos on the land.
