Dhaka South City Corporation (DSCC) Mayor Fazle Noor Taposh on Monday said the under-construction buildings are responsible for 40 percent of dengue infections in the city. “The under-construction buildings created obstruction to control mosquitoes though we are conducting drives regularly. Besides, the authorities also slapped fines in some cases. But no visible steps have been seen from the real estate businessperson,” he said. DSCC mayor revealed this information while speaking at a view-exchange meeting over controlling dengue and chikungunya, held at the Nagar Bhaban.
