Mayor-designate Firhad Hakim on Friday flagged dengue as his primary challenge and said he would focus on running a year-round campaign to raise public awareness about the disease. “We have to make people aware and conscious about dengue because the disease keeps changing in nature. Dengue now stings even in Winter. To combat it, we need to have an awareness and cleanliness drive throughout the year” he said. In Bengal, a period of around four months from the fag end of the monsoon is typically the season when mosquitoes breed rapidly. As the temperature drops below 16-17 degrees Celsius, mosquitoes breed less and dengue becoming less virulent. Apart from combating dengue, Hakim listed prevention of waterlogging in Behala and supply of drinking water to part of Tollygunge and Jadavpur among his priorities.
