With this, the total number of dengue patients in the village rose to over 25, action team leader Gurnam Singh said. Four persons had been referred to Dehra Dun while massive efforts had been initiated for fumigation in the region. The people have been advised to keep their surroundings clean and not allow water to stagnate in or around their homes and agricultural fields. It may be mentioned that about 70 cases had been reported from different districts so far.
